In a knowledge-based patient monitoring system, which component is responsible for organizing and storing data for retrieval?

• A. Data acquisition
• B. Presentation
• C. Coding system
• D. Database

Answer: (D)

Organizing and storing data for retrieval is the job of a database. In a knowledge-based patient monitoring system, the database keeps patient information, vital signs, events, and historical records in a structured, persistent form. It supports how data is stored and related (for example, patient → encounter → measurements), enables efficient searches through indexing and queries, and maintains data integrity through constraints and transactions. Data acquisition collects the raw measurements, presentation shows the data to users, and a coding system standardizes terms; the knowledge base holds the rules and reasoning, but the actual storage and organized retrieval of data is handled by the database.
