Which of the following data model is more flexible?
Correct answer: C. Data relational model
- A. Network data model
- B. Data Hierarchical Model
- C. Data relational model
- D. Object data model
Explanation
The relational data model is generally considered more flexible than the hierarchical and network data models. In the relational model, data is organized into tables (relations) consisting of rows and columns. This structure allows for more flexible querying and manipulation of data compared to the hierarchical and network models, which have more rigid structures.
