The Database Models
Describe how and why the company can benefit from spending time planning at the beginning of the project, instead of just jumping in and developing the applications to meet the perceived needs. To ensure that you give the best response, you choose to describe the 3-level ANSI-SPARC architecture and want to make sure you discuss how the use of this will promote data independence to save time in the long run.
Describe the roles of a data administrator (DA) and a database administrator (DBA); describe the job functions of each and how the tasks they each perform differ. Would you recommend that your company has one person to perform both tasks, or should it hire two people?
Your paper should contain the following information:
Describe the 3-level architecture.
Describe data independence.
Talk about the differences between a DA and a DBA.
Discuss the pros and cons of having a separate DA and DBA or the need for 1 person doing it all.
