Sql Developer

What is SQL?

SQL stands for Structured Query Language. It is a programming language that helps us to access and manipulate databases.

SQL is used to create, read, update, and delete data in a relational database and provides a standardized way to interact with data in a relational database.

SQL is made up of commands that are used to perform data operations such as creating and modifying database objects such as tables, views, indexes, and stored procedures. It also has strong querying capabilities, allowing users to search for and retrieve specific data from a database.

SQL is used in many different applications, such as web applications, business applications, and data analysis. Most popular database management systems, including MySQL, Oracle, SQL Server, and PostgreSQL, support it.
