SQL stands for Structured Query Language and it is a programming language that lets you access and manipulate data in relational databases

Relational databases are systems that store data in tables, which consist of rows and columns.

Each row represents a record and each column represents a field or attribute of the record

SQL allows you to perform various operations on the data, such as creating, reading, updating, and deleting records.

You can also define the structure and schema of the tables, as well as set permissions and constraints on the data. SQL also enables you to query the data and retrieve information that matches certain criteria or conditions


SQL is a standard language that was developed by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) in the 1980s.

However, there are different versions and dialects of SQL that are used by different database management systems, such as MySQL, Oracle, SQL Server, PostgreSQL, and SQLite.

These systems may have their own extensions and features that are not part of the standard SQL
