SQL Database Definition
Relational databases are built using the structured query language (SQL) to create, store, update, and retrieve data. Therefore, SQL is the underlying programming language for all relational database management systems (RDBMS) such as MySQL, Oracle, and Sybase, among others.

SQL helps control information stored in databases, allowing users to retrieve the specific data they’re looking for when they need it. While it’s a simple programming language, SQL is very powerful.

SQL is the most commonly used database language, so it can be used for almost any company that needs to store relational data. Queries within SQL are used to retrieve data from the database, but the queries vary in efficiency.

SQL (Structured Query Language) is a programming language used for managing relational databases. It serves several purposes and has various uses, including:

Database Management

Data Manipulation

Data Retrieval and Reporting

Data Definition Language (DDL)

Data Control Language (DCL)

Data Integrity and Constraints

Database Administration

Data Migration and Integration

SQL is a widely adopted language in the database industry, and its versatility and power make it a fundamental tool for working with relational databases. It provides a standardized way to interact with databases, enabling efficient data management, retrieval, and reporting.
