Assignment Help Database Management System
Reference no: EM13490482

Required:

1) Visualise the computer data entry screens that could be used to capture data for the following business events in Mike's business:
a) Adding a new "member" (so they are able to hire movies)
b) Adding a new "movie" (so it can be hired by members)
c) Rental of "movies" (this screen could include a listing of multiple movies as a customer may hire several movies at a time)
d) Return of rented "movies" (once again, this screen could include a listing of multiple movies).
Draw a representation of one of these data entry screens (indicate to which of the business events, a, b, c, or d, your screen relates)

2) List the "data attributes" you think you would need to capture/store for each of these four business events. What entities do you think would be involved in these business events? Allocate the data attributes to these entities (tables). (Note: I expect that, at this stage, your tables may have "issues" in terms of their "logical" structure; that is, the tables have not yet been "normalized".)

3) List your tables (from requirement 2) using the notation method shown to you during class. Normalise these tables to third normal form (3NF), explaining in detail each step in the process that you have undertaken in reaching your set of 3NF tables.

4) Based upon the 3NF tables that you have produced above, present the logical data structure for your database as a Data Structure Diagram using the notation method shown to you during class.

5) For three (3) possible reports (*) that could be generated from your "logical" database design, explain:
a) what information you would include on that report
b) in general terms, the purpose of that report, and
c) how you have used the "links" between the tables in your database to extract the required information for that report.
