Which data model represents data as a collection of nodes and edges?

  1. Relational Model

  2. Document Model

  3. Graph Model

  4. Columnar Model


Correct Option: C
Explanation:

A graph data model represents data as a collection of nodes (entities) and edges (relationships) between those nodes.

What is the primary advantage of using a graph database over a relational database for interconnected data?

  1. Improved Performance

  2. Enhanced Security

  3. Increased Scalability

  4. Simplified Data Structure


Correct Option: A
Explanation:
