["[Dialogue between User and Assistant on 2024-01-01 00:00]\n<User>I want to tell you about some new discoveries:\nIn this paper, he described a new system for storing and working with large databases. Instead of records being stored in some sort of linked list of free-form records as in CODASYL, Codd's idea was to use a \"table\" of fixed-length records, with each table used for a different type of entity. A linked-list system would be very inefficient when storing \"sparse\" databases where some of the data for any one record could be left empty. The relational model solved this by splitting the data into a series of normalized tables (or relations), with optional elements being moved out of the main table to where they would take up room only if needed. Data may be freely inserted, deleted and edited in these tables, with the DBMS doing whatever maintenance needed to present a table view to the application/user.\n\nThe relational model also allowed the content of the database to evolve without constant rewriting of links and pointers. The relational part comes from entities referencing other entities in what is known as one-to-many relationship, like a traditional hierarchical model, and many-to-many relationship, like a navigational (network) model. Thus, a relational model can express both hierarchical and navigational models, as well as its native tabular model, allowing for pure or combined modeling in terms of these three models, as the application requires.\n\nFor instance, a common use of a database system is to track information about users, their name, login information, various addresses and phone numbers. In the navigational approach all of this data would be placed in a single record, and unused items would simply not be placed in the database. In the relational approach, the data would be normalized into a user table, an address table and a phone number table (for instance). Records would be created in these optional tables only if the address or phone numbers were actually provided.\n<Assistant>Great! I've added this to my knowledge base.", "[Dialogue between User and Assistant on 2024-01-02 00:00]\n<User>I've gathered some additional data to share:\nLinking the information back together is the key to this system. In the relational model, some bit of information was used as a \"key\", uniquely defining a particular record. When information was being collected about a user, information stored in the optional tables would be found by searching for this key. For instance, if the login name of a user is unique, addresses and phone numbers for that user would be recorded with the login name as its key. This simple \"re-linking\" of related data back into a single collection is something that traditional computer languages are not designed for.\n\nJust as the navigational approach would require programs to loop in order to collect records, the relational approach would require loops to collect information about any one record. Codd's solution to the necessary looping was a set-oriented language, a suggestion that would later spawn the ubiquitous SQL. Using a branch of mathematics known as tuple calculus, he demonstrated that such a system could support all the operations of normal databases (inserting, updating etc.) as well as providing a simple system for finding and returning sets of data in a single operation.\n\nCodd's paper was picked up by two people at Berkeley, Eugene Wong and Michael Stonebraker. They started a project known as INGRES using funding that had already been allocated for a geographical database project and student programmers to produce code. Beginning in 1973, INGRES delivered its first test products which were generally ready for widespread use in 1979. INGRES was similar to System R in a number of ways, including the use of a \"language\" for data access, known as QUEL. Over time, INGRES moved to the emerging SQL standard.\n\nAnother approach to hardware support for database management was ICL's CAFS accelerator, a hardware disk controller with programmable search capabilities. In the long term, these efforts were generally unsuccessful because specialized database machines could not keep pace with the rapid development and progress of general-purpose computers. Thus most database systems nowadays are software systems running on general-purpose hardware, using general-purpose computer data storage. However this idea is still pursued for certain applications by some companies like Netezza and Oracle (Exadata).\n\nIBM started working on a prototype system loosely based on Codd's concepts as System R in the early 1970s. The first version was ready in 1974/5, and work then started on multi-table systems in which the data could be split so that all of the data for a record (some of which is optional) did not have to be stored in a single large \"chunk\". Subsequent multi-user versions were tested by customers in 1978 and 1979, by which time a standardized query language \u2013 SQL[citation needed] \u2013 had been added. Codd's ideas were establishing themselves as both workable and superior to CODASYL, pushing IBM to develop a true production version of System R, known as SQL/DS, and, later, Database 2 (DB2).\n\nThe 1980s ushered in the age of desktop computing. The new computers empowered their users with spreadsheets like Lotus 1-2-3 and database software like dBASE. The dBASE product was lightweight and easy for any computer user to understand out of the box. C. Wayne Ratliff the creator of dBASE stated: \"dBASE was different from programs like BASIC, C, FORTRAN, and COBOL in that a lot of the dirty work had already been done. The data manipulation is done by dBASE instead of by the user, so the user can concentrate on what he is doing, rather than having to mess with the dirty details of opening, reading, and closing files, and managing space allocation.\" dBASE was one of the top selling software titles in the 1980s and early 1990s.\n\nThe 1990s, along with a rise in object-oriented programming, saw a growth in how data in various databases were handled. Programmers and designers began to treat the data in their databases as objects. That is to say that if a person's data were in a database, that person's attributes, such as their address, phone number, and age, were now considered to belong to that person instead of being extraneous data. This allows for relations between data to be relations to objects and their attributes and not to individual fields. The term \"object-relational impedance mismatch\" described the inconvenience of translating between programmed objects and database tables. Object databases and object-relational databases attempt to solve this problem by providing an object-oriented language (sometimes as extensions to SQL) that programmers can use as alternative to purely relational SQL. On the programming side, libraries known as object-relational mappings (ORMs) attempt to solve the same problem.\n\n\nXML databases are a type of structured document-oriented database that allows querying based on XML document attributes. XML databases are mostly used in enterprise database management, where XML is being used as the machine-to-machine data interoperability standard. XML database management systems include commercial software MarkLogic and Oracle Berkeley DB XML, and a free use software Clusterpoint Distributed XML/JSON Database. All are enterprise software database platforms and support industry standard ACID-compliant transaction processing with strong database consistency characteristics and high level of database security.\n\nIn recent years there was a high demand for massively distributed databases with high partition tolerance but according to the CAP theorem it is impossible for a distributed system to simultaneously provide consistency, availability and partition tolerance guarantees. A distributed system can satisfy any two of these guarantees at the same time, but not all three. For that reason many NoSQL databases are using what is called eventual consistency to provide both availability and partition tolerance guarantees with a reduced level of data consistency.\n\nThe first task of a database designer is to produce a conceptual data model that reflects the structure of the information to be held in the database. A common approach to this is to develop an entity-relationship model, often with the aid of drawing tools. Another popular approach is the Unified Modeling Language. A successful data model will accurately reflect the possible state of the external world being modeled: for example, if people can have more than one phone number, it will allow this information to be captured. Designing a good conceptual data model requires a good understanding of the application domain; it typically involves asking deep questions about the things of interest to an organisation, like \"can a customer also be a supplier?\", or \"if a product is sold with two different forms of packaging, are those the same product or different products?\", or \"if a plane flies from New York to Dubai via Frankfurt, is that one flight or two (or maybe even three)?\". The answers to these questions establish definitions of the terminology used for entities (customers, products, flights, flight segments) and their relationships and attributes.\n\nHaving produced a conceptual data model that users are happy with, the next stage is to translate this into a schema that implements the relevant data structures within the database. This process is often called logical database design, and the output is a logical data model expressed in the form of a schema. Whereas the conceptual data model is (in theory at least) independent of the choice of database technology, the logical data model will be expressed in terms of a particular database model supported by the chosen DBMS. (The terms data model and database model are often used interchangeably, but in this article we use data model for the design of a specific database, and database model for the modelling notation used to express that design.)\n<Assistant>I've successfully recorded all of this data.", "[Dialogue between User and Assistant on 2024-01-03 00:00]\n<User>I want to tell you about some new discoveries:\nThe final stage of database design is to make the decisions that affect performance, scalability, recovery, security, and the like. This is often called physical database design. A key goal during this stage is data independence, meaning that the decisions made for performance optimization purposes should be invisible to end-users and applications. Physical design is driven mainly by performance requirements, and requires a good knowledge of the expected workload and access patterns, and a deep understanding of the features offered by the chosen DBMS.\n<Assistant>Thank you for sharing. I've noted this information.", "[Dialogue between User and Assistant on 2024-01-04 00:00]\n<User>I'd like to tell you about some recent findings:\nWhile there is typically only one conceptual (or logical) and physical (or internal) view of the data, there can be any number of different external views. This allows users to see database information in a more business-related way rather than from a technical, processing viewpoint. For example, a financial department of a company needs the payment details of all employees as part of the company's expenses, but does not need details about employees that are the interest of the human resources department. Thus different departments need different views of the company's database.\n\nThe conceptual view provides a level of indirection between internal and external. On one hand it provides a common view of the database, independent of different external view structures, and on the other hand it abstracts away details of how the data are stored or managed (internal level). In principle every level, and even every external view, can be presented by a different data model. In practice usually a given DBMS uses the same data model for both the external and the conceptual levels (e.g., relational model). The internal level, which is hidden inside the DBMS and depends on its implementation, requires a different level of detail and uses its own types of data structure types.\n\nDatabase storage is the container of the physical materialization of a database. It comprises the internal (physical) level in the database architecture. It also contains all the information needed (e.g., metadata, \"data about the data\", and internal data structures) to reconstruct the conceptual level and external level from the internal level when needed. Putting data into permanent storage is generally the responsibility of the database engine a.k.a. \"storage engine\". Though typically accessed by a DBMS through the underlying operating system (and often utilizing the operating systems' file systems as intermediates for storage layout), storage properties and configuration setting are extremely important for the efficient operation of the DBMS, and thus are closely maintained by database administrators. A DBMS, while in operation, always has its database residing in several types of storage (e.g., memory and external storage). The database data and the additional needed information, possibly in very large amounts, are coded into bits. Data typically reside in the storage in structures that look completely different from the way the data look in the conceptual and external levels, but in ways that attempt to optimize (the best possible) these levels' reconstruction when needed by users and programs, as well as for computing additional types of needed information from the data (e.g., when querying the database).\n\nDatabase access control deals with controlling who (a person or a certain computer program) is allowed to access what information in the database. The information may comprise specific database objects (e.g., record types, specific records, data structures), certain computations over certain objects (e.g., query types, or specific queries), or utilizing specific access paths to the former (e.g., using specific indexes or other data structures to access information). Database access controls are set by special authorized (by the database owner) personnel that uses dedicated protected security DBMS interfaces.\n\nThis may be managed directly on an individual basis, or by the assignment of individuals and privileges to groups, or (in the most elaborate models) through the assignment of individuals and groups to roles which are then granted entitlements. Data security prevents unauthorized users from viewing or updating the database. Using passwords, users are allowed access to the entire database or subsets of it called \"subschemas\". For example, an employee database can contain all the data about an individual employee, but one group of users may be authorized to view only payroll data, while others are allowed access to only work history and medical data. If the DBMS provides a way to interactively enter and update the database, as well as interrogate it, this capability allows for managing personal databases.\n\nDatabase transactions can be used to introduce some level of fault tolerance and data integrity after recovery from a crash. A database transaction is a unit of work, typically encapsulating a number of operations over a database (e.g., reading a database object, writing, acquiring lock, etc.), an abstraction supported in database and also other systems. Each transaction has well defined boundaries in terms of which program/code executions are included in that transaction (determined by the transaction's programmer via special transaction commands).\n\nA database built with one DBMS is not portable to another DBMS (i.e., the other DBMS cannot run it). However, in some situations it is desirable to move, migrate a database from one DBMS to another. The reasons are primarily economical (different DBMSs may have different total costs of ownership or TCOs), functional, and operational (different DBMSs may have different capabilities). The migration involves the database's transformation from one DBMS type to another. The transformation should maintain (if possible) the database related application (i.e., all related application programs) intact. Thus, the database's conceptual and external architectural levels should be maintained in the transformation. It may be desired that also some aspects of the architecture internal level are maintained. A complex or large database migration may be a complicated and costly (one-time) project by itself, which should be factored into the decision to migrate. This in spite of the fact that tools may exist to help migration between specific DBMSs. Typically a DBMS vendor provides tools to help importing databases from other popular DBMSs.\n\nSometimes it is desired to bring a database back to a previous state (for many reasons, e.g., cases when the database is found corrupted due to a software error, or if it has been updated with erroneous data). To achieve this a backup operation is done occasionally or continuously, where each desired database state (i.e., the values of its data and their embedding in database's data structures) is kept within dedicated backup files (many techniques exist to do this effectively). When this state is needed, i.e., when it is decided by a database administrator to bring the database back to this state (e.g., by specifying this state by a desired point in time when the database was in this state), these files are utilized to restore that state.\n<Assistant>Sure I will remember them.", "[Dialogue between User and Assistant on 2024-01-05 00:00]\n<User>Here's some valuable information I collected:\nStatic analysis techniques for software verification can be applied also in the scenario of query languages. In particular, the *Abstract interpretation framework has been extended to the field of query languages for relational databases as a way to support sound approximation techniques. The semantics of query languages can be tuned according to suitable abstractions of the concrete domain of data. The abstraction of relational database system has many interesting applications, in particular, for security purposes, such as fine grained access control, watermarking, etc.\n\nTucson (/\u02c8tu\u02d0s\u0252n/ /tu\u02d0\u02c8s\u0252n/) is a city and the county seat of Pima County, Arizona, United States, and home to the University of Arizona. The 2010 United States Census put the population at 520,116, while the 2013 estimated population of the entire Tucson metropolitan statistical area (MSA) was 996,544. The Tucson MSA forms part of the larger Tucson-Nogales combined statistical area (CSA), with a total population of 980,263 as of the 2010 Census. Tucson is the second-largest populated city in Arizona behind Phoenix, both of which anchor the Arizona Sun Corridor. The city is  located 108 miles (174 km) southeast of Phoenix and 60 mi (97 km) north of the U.S.-Mexico border. Tucson is the 33rd largest city and the 59th largest metropolitan area in the United States. Roughly 150 Tucson companies are involved in the design and manufacture of optics and optoelectronics systems, earning Tucson the nickname Optics Valley.\n<Assistant>Appreciated. I'll retain these important details.", "[Dialogue between User and Assistant on 2024-01-06 00:00]\n<User>I want to tell you about some new discoveries:\nTucson was probably first visited by Paleo-Indians, known to have been in southern Arizona about 12,000 years ago. Recent archaeological excavations near the Santa Cruz River have located a village site dating from 2100 BC.[citation needed] The floodplain of the Santa Cruz River was extensively farmed during the Early Agricultural period, circa 1200 BC to AD 150. These people constructed irrigation canals and grew corn, beans, and other crops while gathering wild plants and hunting. The Early Ceramic period occupation of Tucson saw the first extensive use of pottery vessels for cooking and storage. The groups designated as the Hohokam lived in the area from AD 600 to 1450 and are known for their vast irrigation canal systems and their red-on-brown pottery.[citation needed]\n<Assistant>Received. I'll store this information.", "[Dialogue between User and Assistant on 2024-01-07 00:00]\n<User>I want to tell you about some new discoveries:\nJesuit missionary Eusebio Francisco Kino visited the Santa Cruz River valley in 1692, and founded the Mission San Xavier del Bac in 1700 about 7 mi (11 km) upstream from the site of the settlement of Tucson. A separate Convento settlement was founded downstream along the Santa Cruz River, near the base of what is now \"A\" mountain. Hugo O'Conor, the founding father of the city of Tucson, Arizona authorized the construction of a military fort in that location, Presidio San Agust\u00edn del Tucs\u00f3n, on August 20, 1775 (near the present downtown Pima County Courthouse). During the Spanish period of the presidio, attacks such as the Second Battle of Tucson were repeatedly mounted by Apaches. Eventually the town came to be called \"Tucson\" and became a part of Sonora after Mexico gained independence from Spain in 1821.\n\nArizona, south of the Gila River was legally bought from Mexico in the Gadsden Purchase on June 8, 1854. Tucson became a part of the United States of America, although the American military did not formally take over control until March 1856. In 1857 Tucson became a stage station on the San Antonio-San Diego Mail Line and in 1858 became 3rd division headquarters of the Butterfield Overland Mail until the line shut down in March 1861. The Overland Mail Corporation attempted to continue running, however following the Bascom Affair, devastating Apache attacks on the stations and coaches ended operations in August 1861.[citation needed]\n\nFrom 1877 to 1878, the area suffered a rash of stagecoach robberies. Most notable, however, were the two holdups committed by masked road-agent William Whitney Brazelton. Brazelton held up two stages in the summer of 1878 near Point of Mountain Station approximately 17 mi (27 km) northwest of Tucson. John Clum, of Tombstone, Arizona fame was one of the passengers. Brazelton was eventually tracked down and killed on Monday August 19, 1878, in a mesquite bosque along the Santa Cruz River 3 miles (5 km) south of Tucson by Pima County Sheriff Charles A. Shibell and his citizen's posse. Brazelton had been suspected of highway robbery not only in the Tucson area, but also in the Prescott region and Silver City, New Mexico area as well. Brazelton's crimes prompted John J. Valentine, Sr. of Wells, Fargo & Co. to send special agent and future Pima County sheriff Bob Paul to investigate. Fort Lowell, then east of Tucson, was established to help protect settlers from Apache attacks. In 1882, Frank Stilwell was implicated in the murder of Morgan Earp by Cowboy Pete Spence's wife, Marietta, at the coroner's inquest on Morgan Earp's shooting. The coroner's jury concluded that Spence, Stilwell, Frederick Bode, and Florentino \"Indian Charlie\" Cruz were the prime suspects in the assassination of Morgan Earp. :250 Deputy U.S. Marshal Wyatt Earp gathered a few trusted friends and accompanied Virgil Earp and his family as they traveled to Benson for a train ride to California. They found Stilwell lying in wait for Virgil in the Tucson station and killed him on the tracks. After killing Stilwell, Wyatt deputized others and rode on a vendetta, killing three more cowboys over the next few days before leaving the state.\n<Assistant>Great! I've added this to my knowledge base.", "[Dialogue between User and Assistant on 2024-01-08 00:00]\n<User>I want to share some knowledge I just acquired:\nBy 1900, 7,531 people lived in the city. The population increased gradually to 13,913 in 1910. At about this time, the U.S. Veterans Administration had begun construction on the present Veterans Hospital. Many veterans who had been gassed in World War I and were in need of respiratory therapy began coming to Tucson after the war, due to the clean dry air. Over the following years the city continued to grow, with the population increasing to 20,292 in 1920 and 36,818 in 1940. In 2006 the population of Pima County, in which Tucson is located, passed one million while the City of Tucson's population was 535,000.\n\nThe city's elevation is 2,643 ft (806 m) above sea level (as measured at the Tucson International Airport). Tucson is situated on an alluvial plain in the Sonoran desert, surrounded by five minor ranges of mountains: the Santa Catalina Mountains and the Tortolita Mountains to the north, the Santa Rita Mountains to the south, the Rincon Mountains to the east, and the Tucson Mountains to the west. The high point of the Santa Catalina Mountains is 9,157 ft (2,791 m) Mount Lemmon, the southernmost ski destination in the continental U.S., while the Tucson Mountains include 4,687 ft (1,429 m) Wasson Peak. The highest point in the area is Mount Wrightson, found in the Santa Rita Mountains at 9,453 ft (2,881 m) above sea level.\n\nTucson is located 118 mi (190 km) southeast of Phoenix and 60 mi (97 km) north of the United States - Mexico border. The 2010 United States Census puts the city's population at 520,116 with a metropolitan area population at 980,263. In 2009, Tucson ranked as the 32nd largest city and 52nd largest metropolitan area in the United States. A major city in the Arizona Sun Corridor, Tucson is the largest city in southern Arizona, the second largest in the state after Phoenix. It is also the largest city in the area of the Gadsden Purchase. As of 2015, The Greater Tucson Metro area has exceeded a population of 1 million.\n\nInterstate 10, which runs southeast to northwest through town, connects Tucson to Phoenix to the northwest on the way to its western terminus in Santa Monica, California, and to Las Cruces, New Mexico and El Paso, Texas toward its eastern terminus in Jacksonville, Florida. I-19 runs south from Tucson toward Nogales and the U.S.-Mexico border. I-19 is the only Interstate highway that uses \"kilometer posts\" instead of \"mileposts\", although the speed limits are marked in miles per hour instead of kilometers per hour.\n\nAt the end of the first decade of the 21st century, downtown Tucson underwent a revitalization effort by city planners and the business community. The primary project was Rio Nuevo, a large retail and community center that has been stalled in planning for more than ten years. Downtown is generally regarded as the area bordered by 17th Street to the south, I-10 to the west, and 6th Street to the north, and Toole Avenue and the Union Pacific (formerly Southern Pacific) railroad tracks, site of the historic train depot and \"Locomotive #1673\", built in 1900. Downtown is divided into the Presidio District, the Barrio Viejo, and the Congress Street Arts and Entertainment District. Some authorities include the 4th Avenue shopping district, which is set just northeast of the rest of downtown and connected by an underpass beneath the UPRR tracks.\n\nAs one of the oldest parts of town, Central Tucson is anchored by the Broadway Village shopping center designed by local architect Josias Joesler at the intersection of Broadway Boulevard and Country Club Road. The 4th Avenue Shopping District between downtown and the University and the Lost Barrio just East of downtown, also have many unique and popular stores. Local retail business in Central Tucson is densely concentrated along Fourth Avenue and the Main Gate Square on University Boulevard near the UA campus. The El Con Mall is also located in the eastern part of midtown.\n\nTucson's largest park, Reid Park, is located in midtown and includes Reid Park Zoo and Hi Corbett Field. Speedway Boulevard, a major east-west arterial road in central Tucson, was named the \"ugliest street in America\" by Life magazine in the early 1970s, quoting Tucson Mayor James Corbett. Despite this, Speedway Boulevard was awarded \"Street of the Year\" by Arizona Highways in the late 1990s. According to David Leighton, historical writer for the Arizona Daily Star newspaper, Speedway Boulevard derives its name from an old horse racetrack, known as \"The Harlem River Speedway,\" more commonly called \"The Speedway,\" in New York City. The street was called \"The Speedway,\" from 1904 to about 1906 before the word \"The\" was taken out.\n\nCentral Tucson is bicycle-friendly. To the east of the University of Arizona, Third Street is bike-only except for local traffic and passes by the historic homes of the Sam Hughes neighborhood. To the west, E. University Boulevard leads to the Fourth Avenue Shopping District. To the North, N. Mountain Avenue has a full bike-only lane for half of the 3.5 miles (5.6 km) to the Rillito River Park bike and walk multi-use path. To the south, N. Highland Avenue leads to the Barraza-Aviation Parkway bicycle path.\n<Assistant>I've processed this information and will remember it.", "[Dialogue between User and Assistant on 2024-01-09 00:00]\n<User>Let me update you with some new information:\nSouth Tucson is actually the name of an independent, incorporated town of 1 sq mi (2.6 km2), completely surrounded by the city of Tucson, sitting just south of downtown. South Tucson has a colorful, dynamic history. It was first incorporated in 1936, and later reincorporated in 1940. The population consists of about 83% Mexican-American and 10% Native American residents. South Tucson is widely known for its many Mexican restaurants and the architectural styles which include bright outdoor murals, many of which have been painted over due to city policy.\n\nA combination of urban and suburban development, the West Side is generally defined as the area west of I-10. Western Tucson encompasses the banks of the Santa Cruz River and the foothills of the Tucson Mountains, and includes the International Wildlife Museum, Sentinel Peak, and the Marriott Starr Pass Resort & Spa, located in the wealthy enclave known as Starr Pass. Moving past the Tucson Mountains, travelers find themselves in the area commonly referred to as \"west of\" Tucson or \"Old West Tucson\". A large undulating plain extending south into the Altar Valley, rural residential development predominates, but here you will also find major attractions including Saguaro National Park West, the Arizona-Sonora Desert Museum, and the Old Tucson Studios movie set/theme park.\n\nOn Sentinel Peak (also known as \"'A' Mountain\"), just west of downtown, there is a giant \"A\" in honor of the University of Arizona. Starting in about 1916, a yearly tradition developed for freshmen to whitewash the \"A\", which was visible for miles. However, at the beginning of the Iraq War, anti-war activists painted it black. This was followed by a paint scuffle where the \"A\" was painted various colors until the city council intervened. It is now red, white and blue except when it is white or another color decided by a biennial election. Because of the three-color paint scheme often used, the shape of the A can be vague and indistinguishable from the rest of the peak. The top of Sentinel Peak, which is accessible by road, offers an outstanding scenic view of the city looking eastward. A parking lot located near the summit of Sentinel Peak was formerly a popular place to watch sunsets or view the city lights at night.\n\nAlso on the north side is the suburban community of Catalina Foothills, located in the foothills of the Santa Catalina Mountains just north of the city limits. This community includes among the area's most expensive homes, sometimes multimillion-dollar estates. The Foothills area is generally defined as north of River Road, east of Oracle Road, and west of Sabino Creek. Some of the Tucson area's major resorts are located in the Catalina Foothills, including the Hacienda Del Sol, Westin La Paloma Resort, Loews Ventana Canyon Resort and Canyon Ranch Resort. La Encantada, an upscale outdoor shopping mall, is also in the Foothills.\n\nThe expansive area northwest of the city limits is diverse, ranging from the rural communities of Catalina and parts of the town of Marana, the small suburb of Picture Rocks, the affluent town of Oro Valley in the western foothills of the Santa Catalina Mountains, and residential areas in the northeastern foothills of the Tucson Mountains. Continental Ranch (Marana), Dove Mountain (Marana), and Rancho Vistoso (Oro Valley) are all masterplanned communities located in the Northwest, where thousands of residents live.\n\nThe community of Casas Adobes is also on the Northwest Side, with the distinction of being Tucson's first suburb, established in the late 1940s. Casas Adobes is centered on the historic Casas Adobes Plaza (built in 1948). Casas Adobes is also home to Tohono Chul Park (a nature preserve) near the intersection of North Oracle Road and West Ina Road. The attempted assassination of Representative Gabrielle Giffords, and the murders of chief judge for the U.S. District Court for Arizona, John Roll and five other people on January 8, 2011, occurred at the La Toscana Village in Casas Adobes. The Foothills Mall is also located on the northwest side in Casas Adobes.\n\nEast Tucson is relatively new compared to other parts of the city, developed between the 1950s and the 1970s,[citation needed] with developments such as Desert Palms Park. It is generally classified as the area of the city east of Swan Road, with above-average real estate values relative to the rest of the city. The area includes urban and suburban development near the Rincon Mountains. East Tucson includes Saguaro National Park East. Tucson's \"Restaurant Row\" is also located on the east side, along with a significant corporate and financial presence. Restaurant Row is sandwiched by three of Tucson's storied Neighborhoods: Harold Bell Wright Estates, named after the famous author's ranch which occupied some of that area prior to the depression; the Tucson Country Club (the third to bear the name Tucson Country Club), and the Dorado Country Club. Tucson's largest office building is 5151 East Broadway in east Tucson, completed in 1975. The first phases of Williams Centre, a mixed-use, master-planned development on Broadway near Craycroft Road, were opened in 1987. Park Place, a recently renovated shopping center, is also located along Broadway (west of Wilmot Road).\n<Assistant>I understand. I'll keep this in mind.", "[Dialogue between User and Assistant on 2024-01-10 00:00]\n<User>I just discovered some interesting information:\nNear the intersection of Craycroft and Ft. Lowell Roads are the remnants of the Historic Fort Lowell. This area has become one of Tucson's iconic neighborhoods. In 1891, the Fort was abandoned and much of the interior was stripped of their useful components and it quickly fell into ruin. In 1900, three of the officer buildings were purchased for use as a sanitarium. The sanitarium was then sold to Harvey Adkins in 1928. The Bolsius family Pete, Nan and Charles Bolsius purchased and renovated surviving adobe buildings of the Fort \u2013 transforming them into spectacular artistic southwestern architectural examples. Their woodwork, plaster treatment and sense of proportion drew on their Dutch heritage and New Mexican experience. Other artists and academics throughout the middle of the 20th century, including: Win Ellis, Jack Maul, Madame Cheruy, Giorgio Belloli, Charels Bode, Veronica Hughart, Edward and Rosamond Spicer, Hazel Larson Archer and Ruth Brown, renovated adobes, built homes and lived in the area. The artist colony attracted writers and poets including beat generation Alan Harrington and Jack Kerouac whose visit is documented in his iconic book On the Road. This rural pocket in the middle of the city is listed on the National Register of Historic Places. Each year in February the neighborhood celebrates its history in the City Landmark it owns and restored the San Pedro Chapel.\n\nSoutheast Tucson continues to experience rapid residential development. The area includes Davis-Monthan Air Force Base. The area is considered to be south of Golf Links Road. It is the home of Santa Rita High School, Chuck Ford Park (Lakeside Park), Lakeside Lake, Lincoln Park (upper and lower), The Lakecrest Neighborhoods, and Pima Community College East Campus. The Atterbury Wash with its access to excellent bird watching is also located in the Southeast Tucson area. The suburban community of Rita Ranch houses many of the military families from Davis-Monthan, and is near the southeastern-most expansion of the current city limits. Close by Rita Ranch and also within the city limits lies Civano, a planned development meant to showcase ecologically sound building practices and lifestyles.\n<Assistant>Appreciated. I'll retain these important details."]
