Personal Trainer, Inc. owns and operates fitness centers in a dozen Midwestern cities. The centers have done well, and the company is planning an international expansion by opening a new “supercenter” in the Toronto area. Personal Trainer’s president, Cassia Umi, hired an IT consultant, Susan Park, to help develop an information system for the new facility. During the project, Susan will work closely with Gray Lewis, who will manage the new operation.
Working as an IT consultant for Personal Trainer, Susan Park used data and process modeling tools to create a logical model of the proposed information system. Now she wants to build an object-oriented view of the system using O-O tools and techniques.
