The owner of two pizza parlors located in adjacent towns wants to computerize and in- tegrate sales transactions and inventory man- agement within and between both stores. The point-of-sale component must be easy to use and flexible enough to accommodate a va- riety of pricing strategies and coupons. The inventory management, which will be linked to the point-of-sale component, must also be easy to use and fast. The systems at each store need to be linked so that sales and in- ventory levels can be determined instantly for each store and for both stores combined. The owner can allocate $40,000 for hardware and $20,000 for software and must have the new system operational in three months. Training must be short and easy. Briefly describe three alternative systems for this situation and ex- plain how each would meet the requirements and constraints. Are the requirements and constraints realistic? Why or why not?
