Which type of logical data structure uses graphics to illustrate relationships among data elements?

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.
