What is the primary purpose of object-relational mapping (ORM)?

• A. To facilitate database migrations
• B. To map application objects to the appropriate objects in a relational database
• C. To optimize database performance
• D. To simplify SQL syntax

Answer: (B)

The primary purpose of object-relational mapping (ORM) is to bridge the gap between the object-oriented programming paradigm and relational database systems. This technique allows developers to interact with the database using their application’s native programming language objects instead of writing complex SQL queries. By mapping application objects to the corresponding database entities, ORM enables intuitive manipulation of data as objects, making it easier to work with the database in a way that is consistent with the architecture of modern programming languages. In particular, ORM frameworks handle the conversion of data between the program's objects and the database's tables, ensuring that interactions are seamless and minimizing the potential for errors during data access. This abstraction not only simplifies common database operations but also helps maintain clean and maintainable code. The other options focus on different aspects of database management or optimization, which, while important, do not capture the essence of what ORM is designed to achieve.
