Which type of databases focuses on the use of objects?

• A. Relational databases
• B. Object-oriented databases
• C. Distributed databases
• D. Hierarchical databases

Answer: (B)

Object-oriented databases are designed specifically to handle data in terms of objects, which are instances of classes, in a way that aligns with object-oriented programming principles. This type of database allows for the storage of complex data types and relationships by treating data as objects that can encapsulate both state (attributes) and behavior (methods). In the context of software development, this approach facilitates a closer relationship between the database and the programming language used to manipulate the data, leading to more seamless integration and use of the database in applications that rely heavily on object-oriented design. The object-oriented database model supports features such as inheritance and polymorphism, enabling developers to create richer data structures that can be more easily managed and manipulated. In contrast, relational databases are structured around tables and relationships between them, focusing on a framework of rows and columns rather than objects. Distributed databases are designed to spread data across multiple physical locations, emphasizing the distribution of data rather than its object orientation. Hierarchical databases organize data in a tree-like structure, where each record has a single parent and can have multiple child records, which is quite different from the object-based paradigm.
