E

Answer to Question 2

Databases need redesigning for two reasons. First, it is not always easy to build a database correctly the first time, and changes in an organization's business process may create the need for a change. With regards to the first reason, even if the data modeling process captured all the users' requirements, translating the requirements into a correct data model and database design can be difficult. Almost inevitably, there will be errors that need to be corrected. With regards to the second reason, information systems and the organizations that use them influence each other to the point where they can be said to create each other. As the organization changes so will the user requirements, which will necessitate database redesign.
