group project part 3 developing a class diagram 1

/in /by

A class diagram illustrates the data elements needed to implement a system, as well as the relationship between elements. A good diagram works without data duplication, meets all system requirements, is in at least third normal form (3NF), and stands up to rigorous testing. A class diagram intended for use with an object-oriented database will include methods. Since you are building a relational database, you will not include methods in the class diagram.

To prepare for this Project:

  • Review the “Sample UML Class Diagram” document in the Learning Resources.
  • Review any of the optional class diagram and modeling articles in the Learning Resources as necessary.
  • Review the “Information System Project Case Study” document in the Learning Resources.
  • Note that the number of classes and attributes will depend upon your analysis of the requirements and how you normalize the design. Different solutions are possible.

To complete this Project

  • A UML class diagram that represents the data requirements for the case study, accounting for all business information needs (reports and forms). The diagram should include classes, attributes, and relationships necessary to store all the information required to implement a successful system. Use the class diagram notation as shown in the “Sample UML Class Diagram” document included in the Learning Resources.
  • Be sure that the final diagram is in at least third normal form (3NF).
