In data modeling, what is the term for a visual representation of the relationship between different entities in a database?

Solution (By Examveda Team)

Data modeling is like creating a blueprint for your data. It shows how different pieces of information relate to each other.

This question asks about a visual representation – something you can *see* – that shows how different parts of your database are connected.

Let's look at the options:

A. Data Dictionary: This is a list that describes the data, but it's not a visual representation of relationships.

B. Data Flow Diagram (DFD): This shows how data moves *through* a system, not the relationships between data *itself*.

C. Entity-Relationship Diagram (ERD): This is exactly what we're looking for! It uses boxes and lines to show different types of information (entities) and how they're connected (relationships).

D. Data Cube: This is used for data analysis, not for representing relationships in a database design.

Therefore, the answer is C. Entity-Relationship Diagram (ERD) because it's the visual tool used to show how different parts of a database relate to each other.
