* Understanding Data Models:
* A data model is a logical data structure that uses visual representations (e.g., diagrams) to illustrate relationships among data elements.
* It helps in organizing data and defining how various entities interact within a database system.
* Application in the Scenario:
* The use of graphics to illustrate data relationships aligns with the concept of a data model.
* Examples include entity-relationship diagrams (ERDs) and conceptual models.
* Why Other Options Are Incorrect:
* Option A (Integration): Integration connects systems or data sources but does not represent data relationships graphically.
* Option B (Structured Query Language): SQL is used for querying and managing databases, not visualizing data structures.
* Option D (Relational database model): This defines a specific type of database architecture but does not inherently involve graphics.
