What process is illustrated by the interaction between database systems and users’ needs for information?

The process demonstrated by the interaction between database systems and users' needs for information is information retrieval. This involves the methods and techniques used to obtain data from a database in a format that users can utilize to meet their specific information needs. Information retrieval is focused on enabling users to gain access to the relevant data efficiently, ensuring that they can find what they are looking for among potentially vast amounts of stored information.

In practice, this means that when users query a database, the system interprets their request and retrieves the necessary data that matches their criteria, presenting it in a user-friendly manner. The effectiveness of this process relies on various factors, such as the database's structure, the indexing of information, and the querying techniques employed.

Other processes, such as data processing, focus on transforming raw data into a more meaningful format without necessarily addressing the user's need for specific information. Data interchange refers to the transfer of data between different systems or formats, which is not directly related to how users access information. System design pertains to the overall architecture and organization of the database system itself, rather than the specific interaction between users and the information they seek.
