Which database management systems support the SQL language?

SQL (Structured Query Language) is supported by most modern database management systems (DBMS). Here are the main ones:

• MySQL — a popular open-source relational DBMS.
• PostgreSQL — a powerful object-relational DBMS with advanced features.
• Microsoft SQL Server — a commercial DBMS from Microsoft.
• Oracle Database — a commercial DBMS with extensive functionality.
• SQLite — a lightweight embedded DBMS.
• MariaDB — a fork of MySQL with additional features.

Almost all relational databases support standard SQL for creating, reading, updating, and deleting data (CRUD). Some NoSQL databases may have limited or adapted support for SQL-like queries, but classic SQL is characteristic of relational DBMS.
