SQL
SQL
SQL allows you to insert, update, delete, and search data. Relational database management systems (RDBMS) such as PostgreSQL, Oracle Database, MySQL, and MS SQL Server support the SQL language. PostgreSQL, an open-source system, can process both relational (SQL) and non-relational (JSON) data and offers advanced features such as triggers, subqueries, and foreign keys. MS SQL Server, on the other hand, is an RDBMS developed by Microsoft that organizes data in tables and creates relationships between tables.
