What is the primary focus of abstraction in information systems?

The primary focus of abstraction in information systems is to present only relevant information. Abstraction allows for the simplification of complex systems by filtering out unnecessary details and emphasizing the information that is most pertinent to the user or the task at hand. By concentrating on relevant data, users can make decisions and understand systems without being overwhelmed by extraneous information.

Abstraction is a fundamental concept in both software design and data management; it helps in building more efficient and user-friendly interfaces and systems. In practical terms, this means that, for example, a database might provide a user with a simplified view of data, showing only the fields that are necessary for a specific operation, while hiding the underlying complexity involved in the database's structure and data relationships.

In contrast, the other options focus on different aspects of data handling and system security that, while important, do not align specifically with the concept of abstraction. Hiding sensitive data completely relates to security measures, ensuring data integrity pertains to the accuracy and consistency of data, and creating backups of all data is focused on data recovery measures rather than the filtering and presentation of relevant information.
