What is the primary function of a database?

The primary function of a database is to organize and manage data efficiently. This involves not just storing data but also facilitating processes that allow for easy retrieval, manipulation, and management of that data in ways that support various applications and user needs. A well-structured database allows for efficient querying, updates, and data integrity, thereby enhancing overall data accessibility and usability.

While storing data is a critical aspect of databases, the emphasis on organization and management of that data ensures that it can be used effectively. This includes the ability to handle relationships between different data entries and ensuring that the data remains consistent and secure. Thus, it is the combined capability of organization, management, storage, and retrieval that defines the essence of a database's function, making option B the most comprehensive and accurate choice.
