Homework Assignment – Data ModelingBecause of your expertise in database design and administration, you have been asked to develop a system to track committee activities for the annual hospital 5K Walk-a-Thon. You have the following facts:There are several committees
Each committee has several members
Each committee has a chairperson
You wish to collect the following information on the members of each committee:
Name
Address
Telephone
Date of joining the committee
Special skills
You wish to collect the following information on the chairperson:
Name
Address
Telephone
Committee
Date became chairperson
You also wish to track the following information on an ongoing basis:
Meetings or activities of each committee
Committee meeting or activity date attendance for both chairperson and members
Revenues and Expenses of each activity
At the end of the event you want to determine accomplishments of individuals – awards are given for length of service, service as chairperson, and revenue greater than $100 earned by a particular activity. (Note: These would be done as queries, so you need to be sure you are collecting the required data)
Determine the entities, attributes, and relationships of the above information and use it to develop a conceptual data model as discussed in class. Start by deciding what the entities are about which you will collect data. Also include a chart explaining the model. See pages 176-178 in the text by Johns on e-reserve for an example. HINTS: Be careful in setting up fields to follow the rules of normalization, i.e., no multiple entries per field. Think about it and don’t just use the names I’ve listed above! Don’t include calculated fields. Also, create the minimum number of tables to do the job; maybe you can include something in a table without creating another one!Products to turn in: undefinedConceptual data model diagram. Use SmartDraw or another flowchart or drawing program to complete this.
