Using a structure chart, represent the procedural structure of a simple inventory/accounting system for a small store (perhaps a rivately owned curio shop in a resort community). What modules in your system must be modified because of changes in sales tax laws? What modules would need to be changed if the decision is made to maintain a record of past customers so that advertising can be mailed to them?
And design an object-oriented solution to the previous problem and represent it by a class diagram.
