Shipment Tracking System Initial Design

The main goals of the new system where as follows:

1. Replace the excel spreadsheets used with an SQL database and a client side program to access it.
2. Automate the manual process of performing Syspro functions.
3. Use XML as the format for the data sent to and received from K&N and LOCTON. K&N has an EDI interface that could later be used to automate the data flows between ZF and K&N.

The next step was to design a system to meet the requirements as follows:

1. Produce a number of use cases and use case diagrams.
2. Model the system work flows with a sequence diagram for each use case.
3. Do risk analysis.
4. Assign responsibilities and produce a domain model.
5. Produce interaction diagrams for the main system functions.
6. Produce a class diagram and a context diagram.
7. if required produce a state diagram for certain objects.
