The managers at Wild Wood Apartments are anxious to see some progress on their database. They have answered your questions and now want to see some results. They really want the new database to be in place before the beginning of the new fiscal year in July. It is time to design the database.
To do
1. Review all the requirements and business rules.
2. Define your entities and attributes and the relations that
exist between them.
3. Create a logical model using crow’s feet notation in Visio
or hand draw it on graph paper if you prefer.
4. Add all the entities and their attributes.
5. Identify the key fields for each entity and the foreign
keys.
6. Analyze the diagram. Identify which role (i.e., domain,
linking, lookup, or weak) each entity plays in your
database.
7. Have another student or a group review it for the
following:
a. Are all the major components of the Wildwood Apartments business model represented by domain entities?
b. Does each entity contain the appropriate attributes to fully describe it and meet the business rules you have gathered so far?
c. Does every entity have an appropriate primary key defined?
d. Are all many-to-many relationships resolved into one-to-many relationships by linking tables?
e. Are the relationships valid (no cross relationships)? Is the appropriate entity is defined as the one side of a one-to-many relationship? Do the tables have appro- priate foreign keys?
f. Are lookup tables used for attributes that have a set list of values?
8. Documentation: Be sure to store your ERDs in your database notebook.
