Database development process involves mapping of conceptual data model into:
Correct answer: C. Implementation Model
- A. Object Oriented Data Model
- B. Network Data Model
- C. Implementation Model
- D. Hierarchical Data Model
Explanation
The conceptual data model is a high-level representation of the data that is needed by the database system. It describes the entities (data objects) and their relationships, but it does not specify how the data will be stored or manipulated.The implementation model, on the other hand, is a low-level representation of the data that is specific to a particular database management system (DBMS). It specifies how the data will be stored in the database, such as the data types of the attributes and the relationships between the entities.The mapping process involves taking the conceptual data model and translating it into an implementation model that can be understood by the DBMS. This process is essential for ensuring that the database can store and manage the data that is needed by the application.In conclusion, the implementation model is the correct answer to the question because it is the low-level representation of the data that is specific to a particular DBMS. The conceptual data model is a high-level representation of the data, and the object-oriented data model, network data model, and hierarchical data model are all different types of data models that can be used to represent data.
