DBMS-Object Oriented Database Questions and Answers
DBMS Object Oriented Database questions with answers explore how object-oriented principles are integrated into traditional database management systems. This topic is common in programming interview questions with answers for companies like TCS, IBM, and Wipro. It combines object-oriented programming concepts—like encapsulation, inheritance, and polymorphism—with relational database structures. Understanding OODBMS helps developers manage complex data efficiently in modern applications. Practicing such questions enhances your grasp of database modeling and boosts performance in technical interviews.
