Suppose that Heather Sweeney wants to include records of her consulting services in her database. Extend the data model in Figure 4-21(c) to include CONSULTING_ PROJECT and DAILY_PROJECT_HOURS entities. CONSULTING_PROJECTcontains 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.

Normalization

Normalization is the process of eliminating redundancy in a database by organizing the data into several smaller tables. The large tables are normalized (converted) into smaller tables by using normalization rules, so that a database administrator can easily handle them. It also eliminates insertion, deletion, and update anomalies.
