What is the primary goal of using a database engine within a DBMS?

The primary goal of using a database engine within a Database Management System (DBMS) is to facilitate data storage and retrieval. The database engine acts as the core component that handles data operations, allowing for efficient storage, organization, and access to data stored in a database. It provides essential functionalities such as query processing, transaction management, and indexing, ensuring that users can efficiently store new data and retrieve existing data when needed.

These capabilities are crucial for maintaining the integrity and performance of the database, making it possible for users to execute queries and access data swiftly and reliably. By focusing on the core functions of data handling, the database engine enables applications to interact with the data in a way that is both structured and efficient.

The other options, while relevant to the broader context of database management, do not represent the primary function of a database engine. Designing user interfaces pertains to the user experience aspect, managing data workflows relates more to the overall architectural processes in data handling, and maintaining backups, although vitally important for data security and recovery, represents a specific maintenance task rather than the fundamental operation of a database engine.
