How to create the data modeling

BHIS 461 - INFORMATION SYSTEMS FOR HIM

Homework Assignment - Data Modeling

Because 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:

1. There are several committees
2. Each committee has several members
3. Each committee has a chairperson
4. You wish to collect the following information on the members of each committee:
5. Name
6. Address
7. Telephone
8. Date of joining the committee
9. Special skills
10. You wish to collect the following information on the chairperson:
11. Name
12. Address
13. Telephone
14. Committee
15. Date became chairperson
16. You also wish to track the following information on an ongoing basis:
17. Meetings or activities of each committee
18. Committee meeting or activity date attendance for both chairperson and members
19. Revenues and Expenses of each activity
20. 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: 

1. Conceptual data model diagram.  Use SmartDraw or another  flowchart or drawing program to complete this.
2. Chart explaining model.
