What database management systems have you used in your projects?

In my projects, I have used various database management systems (DBMS), depending on the requirements of the task:

• Relational DBMS:

  • Microsoft SQL Server — often used for enterprise applications in C# with Entity Framework.
  • PostgreSQL — used for open-source projects and where advanced SQL support is needed.
  • MySQL — used in web projects.

• NoSQL DBMS:

  • MongoDB — for storing documents and flexible data schemas.
  • Redis — for caching and fast data access.

In C# projects, these are usually integrated with the DBMS through ORM, such as Entity Framework, which simplifies data handling and allows writing queries in C#.
