The primary use of Structured Query Language (SQL) is communicating with a relational database.
Databases are where your customers’ data is stored, and SQL makes it possible to move it from the database to your application, or website, and the other way around.
A relational database is like a database with a power boost. “Relational” means that the database is divided into interconnected tables, all of them related to others, so that you can access multiple tables at once to generate the desired result.
Thanks to this, instead of holding all data in one place, it is placed in smaller units that are much easier to manage and maintain.
In practice, a relational database stores your data in multiple tables, and you can access any table and data that you need, as long as your app is sending the right SQL queries.
There are two types of queries – ones define data, and others manipulate it. Defining in this context means creating and deleting database structures. Manipulating it means inserting new data, modifying existing data, or deleting data.
Data protection and privacy has never been as important as today, which is one of the reasons why SQL server database developers can make, or break your product. So choose them wisely.
