In enterprise data modeling, which is incorrect?

 

  • A.You review current systems.
  • B.You implement the new database.
  • C.You describe the data needed at a very high level of abstraction.
  • D.You plan one or more database development projects.

Answer: B

Correct answer: You implement the new database.

Enterprise data modelling is a planning activity: reviewing the current systems, describing the data at a high level of abstraction, and identifying the database projects worth doing. Implementation comes several steps later, after conceptual, logical and physical design, and is not part of it.
