Web-based developers use SQL (Search Query Language) when they want to store data from a web-based application in a relational database. Most web-based applications currently use relational databases to store their data.
Web-based developers enjoy using Python for the following two reasons: code readability and extensibility. Both of these reasons have contributed to the creation of several highly specialized and popular libraries. Developers interested in scientific computing or natural language processing with a high-level language will find that Python is a good fit.
Web-based developers use Ruby for many reasons, but the primary one is the popularity of its web application framework, Ruby on Rails (Rails). However, many new developers cite Rail’s greatest strength as its greatest weakness: It’s relatively easy for them to create a web-based application, but the entire process also seems a bit magical.
