Heather Sweene

Suppose that Heather Sweeney wants to include records of her consulting services in her database. Extend the data model in Figure 4-20(c) to include

 

CONSULTING_PROJECT and DAILY_PROJECT_HOURS entities.

CONSULTING_PROJECT contains data about a particular project for one of Heather’s customers, and DAILY_PROJECT_HOURS contains data about the hours spent and a description of the work accomplished on a particular day for a particular project. Use strong and/or weak entities, as appropriate. Specify minimum and maximum cardinalities. Use the IE Crow’s Foot E-R model for your E-R diagrams.
