 WHAT IS SQL?

SQL stands for Structured Query Language. It is a programming language specifically designed for managing and manipulating relational databases. SQL provides a standardized way to interact with databases, allowing users to perform various operations such as creating, modifying, and querying databases and their data.

Here are some key aspects of SQL:

• Database Management: SQL allows users to create and manage databases, including defining their structure, tables, relationships, and constraints.
• Data Manipulation: SQL provides commands for inserting, updating, and deleting data within a database. These commands enable users to modify the contents of tables, add new records, or remove existing ones.
• Data Querying: SQL allows users to retrieve data from a database using the SELECT statement. Queries can be formulated to filter, sort, and aggregate data based on specific criteria, making it easier to extract relevant information.

SQL is widely used in various database management systems, including popular ones like MySQL, PostgreSQL, Oracle Database, Microsoft SQL Server, and SQLite. It has become a fundamental tool for managing and interacting with structured data in a relational database environment.
