Question
An entity-relationship diagram provides a graphical representation of the
a. Schemab.
c. Frameworkd.
Modules
Solution
The correct answer is b. Context.
An entity-relationship diagram (ERD) is primarily used to illustrate the relationships between entities in a particular context, such as a database structure. It helps in visualizing how different data points relate to one another, providing a clear context for understanding data relationships and constraints within a system. Here’s a quick breakdown of the options:
- Schema - Refers to the overall structure of a database but is not what ERDs represent directly.
- Context - Correctly represents the framework within which relationships and entities are displayed.
- Framework - A broader term that encompasses systems and structure but is less specific than context.
- Modules - Refers to distinct units of functionality or features within a system, not directly represented by an ERD.
Thus, an "entity-relationship diagram provides a graphical representation of the context" in which entities exist and interact.
