1. Overview

Carry out the early stages of building a domain model for the mail order inventory system described below.

1.1 Deliverables

1. Give an initial list of candidate classes and responsibilities.

2. Give an initial set of CRC cards.

3. Prepare a set of 3 UML class relationship diagrams highlighting important relations among the discovered classes. These diagrams must be accompanied by explanatory text.

Each diagram must provide a coherent picture of relations among 3-5 classes. Together, they must involve at least three different types of relations. (In order of preference: generalization, association, composition, aggregation, dependency. If one of these relation types does not occur in your model, skip it and use another.)

Compile these three deliverables into a single PDF file.

2. Submitting the Assignment

CRC cards can be simulated using the "table" facility available in most word processors. Create a 2-column table for each card, with the class name appearing in bold at the top of the left column or in a top row spanning the two columns.

3. System Description: Mail Order Warehousing

Fancy Oriental Objects (FOO), Incorporated, is a mail-order company specializing in overpriced knick-knacks and kitsch imported from Eastern Asia. FOO processes orders via a number of regional warehouses. Each warehouse has responsibility for inventory management and order processing. Because demand of some products varies by region, the inventory at the warehouses may vary considerably. Also, the products offered tend to vary considerably from year to year.

Customer orders are received at the central mail-order facility (MOF). The MOF staff check the list of products ordered against the available stock in the various warehouses and divides the order among the warehouses, sending a packing slip to each warehouse. The packing slip tells the warehouse which products from the total order that warehouse should ship to the customer.

The MOF prepares a single invoice for each customer order, indicating the items to be shipped to fulfill the order,their expected shipping date, and various charges to the customer including the price of the items, shipping and handling costs, and sales taxes. This invoice is mailed separately to the customer.

FOO would like to have a common inventory- and order-tracking system across all of its warehouses, to replace the current amalgamation of manual processing and low-level computer tools (spreadsheets, word processors) used to support this process.
