What are examples of dbms and rdbms and oordbms?

Examples of Database Management Systems (DBMS) include Microsoft Access and SQLite, which are suitable for smaller applications. Relational Database Management Systems (RDBMS) examples are MySQL, PostgreSQL, and Oracle Database, which organize data into tables with relationships. Object-Oriented Database Management Systems (OODBMS) include db4o and ObjectDB, which store data in the form of objects, similar to object-oriented programming. Each type serves different needs based on the structure and relationships of the data.
