Correct answer: B. Network data model
- A. Object-oriented data
- B. Network data model
- C. Implementation
- D. Hermetic model
Explanation
A network data model is one type of logical data model that allows for more complex relationships between entities compared to the hierarchical model. It uses sets to link entities together, providing more flexibility for representing real-world scenarios. The conceptual data model captures the high-level entities and relationships, and the network data model refines this into a more detailed structure suitable for database implementation
