Question

During the implementation phase of developing a database system, what happens to the data model?

1) It is transformed into a database design.
2) It is used to create a user interface.
3) It is discarded and a new data model is created.
4) It is converted into a programming language.

Answer 1

During the implementation phase of developing a database system, the data model is transformed into a database design, which serves as the blueprint for creating the actual database system.

Step-by-step explanation:

During the implementation phase of developing a database system, the data model is transformed into a database design. The database design is a more detailed representation of the data model and includes specifications for tables, relationships, and constraints. It serves as the blueprint for creating the actual database system. The data model does not get discarded in this phase, but rather refined and expanded upon to create a comprehensive database design.
