CASE STUDY PART 3

ACTIVITY 3
1. Review the NLA fact-finding summary and all other information you have about the required system and critically analyse this for duplications and inconsistencies.
2. Draw an ERD diagram with crows-foot cardinality as well as a domain model class diagram with notation. Assume that system entities include farms, customers, status as Regular or Variable, orders, vegetables with associated price per unit, and delivery person (at minimum), as well as organic certified.
3. Design tables - making sure each table only refers to one "thing". As you create the database design, identify primary and foreign keys by underlining primary keys, and making foreign keys italic.
4. If you add primary keys which use codes - for example a code for the farmID, then identify the format of these codes.
5. Create suitable sample data to populate the fields for at least three records in each table.
6. Include the following in your report:
• The ERD or domain model class diagram you have completed;
• The database design (schemas);
• Formats of codes used;
• Sample data for each table

CASE STUDY 4
You are now making sure that you have sufficient models to understand the new system. In reviewing the models (use-cases diagrams, including activity diagrams) you realise that you have not included a system sequence diagram for any of the use cases.

After creating this, you are now ready to review the options for a new system and make a recommendation to Ardell and Richard.

ACTIVITY 4
1. Create a system sequence diagram for one of the use cases identified in Activity 6. Add this system sequence diagram to your report in the appropriate area.
2. Search online for potential commercial software packages for 100% Organic Co. Identify two packages, and compare their features, and their suitability to be used as the new system.
3. Present at least three options for the new system in your report. One of these must be in-house development, and two of the others may be the commercial packages as identified in (3) above.
4. Review your feasibility analysis for the new system. Taking all options into consideration, make a recommendation for the new system, in your "Conclusion and Recommendations" section.

REPORT
You have completed the contents of your report, and now need to make sure that the report is presented professionally, as it will be shown to Richard, Ardell and owners of farms intending to work with 100% Organic Co., as well as any potential investors in the new system, and the expanding prospects for 100% Organic Co..
