What database management systems do you use in your projects?

In projects for database management, the following DBMSs are often used:

• MySQL — a popular open-source relational DBMS, well-suited for web applications.
• PostgreSQL — a powerful relational DBMS with advanced features, supports complex queries and data types.
• Oracle Database — a commercial DBMS with extensive functionality, often used in large corporate systems.
• Microsoft SQL Server — a relational DBMS from Microsoft, integrates with the Windows ecosystem.
• MongoDB — a document-oriented NoSQL database, convenient for storing unstructured data.

The choice depends on project requirements, data types, and scalability. In QA automation, it is important to be able to work with the DBMS used in the project for data verification and integration testing.
