ESSS CASE STUDY SOLUTIONS MILESTONE 2

We have chosen to focus only on the use cases that will be most used. Provide a single source of entry for employee information and have the data available real-time. This solution is slightly different than the solution given in Milestone 2 simply because later milestones provided more information. Subject to interpretation,this diagram is in third normal form, which is the bulk of the assignment for Milestone 5. During this milestone you will first construct a context diagram to establish project scope and boundaries.

Identify external and temporal business events for a system. None Need to verify which information should and should not be displayed. A building where employees work in various rooms. For example, we have encountered clients who have mentioned that they envisioned expected? An organizational unit within the company to category employees A geographic location where the company has a vested interest and conducts business in some fashion. Merge event diagrams into a system data flow diagram. Students shoud be able to identify at least the major entities below.

Employyees unable to quickly locate other employees,company solutlons being sent to the wrong address and payroll checks unable to be delivered. It is important to ensure that students use the proper controls when designing their screens.
