An Object-Oriented Database (OODB) is a type of database that stores data in the form of objects, similar to how data is represented in programming languages like Java or C++. This approach allows for more complex data structures and relationships, making it easier to model real-world entities. Objects can contain both data and methods, enabling more efficient data manipulation and retrieval. OODB systems support features like inheritance and encapsulation, which are key principles of Object-Oriented Programming. This allows developers to create more flexible and reusable code. OODBs are particularly useful in applications that require complex data representations, such as CAD systems or multimedia databases.
