SQL is the standard programming language used to design, create and manage relational databases. Relational systems are made up of a set of tables containing rows and columns of data. Each column in a table represents a category of data, such as a customer name or address, and each row contains a data value for the intersecting column.
Functions of SQL include:
- Modifying database table and index structures
- Adding, updating and deleting rows of data
- Retrieving information from a database for transaction processing and analytics
- Generating tables and other database projects
Used since the 1970s, SQL will be a technology staple for the foreseeable future. It's a universal coding language that will help you transition into learning other computer languages, including JavaScript and Python.
SQL doesn’t require prior programming experience, so it’s a great coding language to learn if you’re just getting into programming. But with so many resources available to learn SQL, where do you begin?
