Pine Valley Case Exercises

Development work on PVF's new customer tracking system is proceeding according to plan and is on schedule. The project team has been busy designing the human interfaces, and you have just completed the new tracking system's Customer Profile Form, Products by Demographics Summary Report, and Customer Purchasing Frequency Report.

Because you are not ready for a new task, Jim Woo asks you to prepare logical data models for the form and two reports that you have just designed and drop them by his office this afternoon. At that time, the two of you will prepare a consolidated database model, translate the customer tracking system's E-R data model into normalized relations, and then integrate the logical data models into a final logical data model for the customer tracking system.

1. Develop logical data models for the form and two reports mentioned in the case scenario.
2. Perform view integration on the logical models developed for part a.
3. What view integration problems, if any, exist? How should you correct these problems?
4. Have a fellow classmate critique your logical data model. Make any necessary corrections.
