What database management systems have you used in your projects?

In C/C++ projects, I used various DBMSs depending on the requirements. For example:

• SQLite — for embedded and lightweight applications where a simple file-based database is needed.
• MySQL and PostgreSQL — for larger projects with client-server architecture.
• Sometimes I used Oracle or MS SQL Server if the project required enterprise solutions.

For interacting with databases, I used libraries such as ODBC, libpq (for PostgreSQL), or specialized ORMs if possible.
