SQL is a standard programming language that is popularly used in order to create, design, and manage relation-based databases. These relational systems are built up of a set of tables that consist of several columns and rows made from data. Each one of these columns is a representation of a certain category of data. For instance, it can be the name of a customer or their address and all of these rows contain a data value for its intersecting column.
Founded back in 1970, the SQL language has been in use since then. It is useful in modifying a certain database and creating index structures; adding, deleting, or even updating data rows; bringing up information from a database that can further be used for the processing of transactions and analytics; or for generating database projects such as tables. Now you must be wondering, where do you start your journey of learning SQL from? Let us clear that out for you!

There is a vast array of free but efficient and useful tutorials available on the internet, such as the few SQL database fundamental tutorials by Microsoft. These tutorials will equip you with an interesting introduction and deep knowledge of all the terminologies, skills, and concepts related to SQL databases. A few of the tutorials are interactive, which means that you will be able to manipulate data in order to create your own queries so that you can test your knowledge of SQL.
