Can you name the database management systems you are familiar with?

I am familiar with several database management systems (DBMS) that are often used in C# development:

• Microsoft SQL Server — a relational DBMS from Microsoft, well integrated with .NET.
• SQLite — a lightweight embedded DBMS, often used for mobile and desktop applications.
• PostgreSQL — a powerful open-source relational DBMS with support for extensions.
• MySQL — a popular open-source relational DBMS.
• Oracle Database — a commercial relational DBMS with extensive features.

In C#, ORM tools like Entity Framework, Dapper, and others are often used to work with these DBMSs.
