Planning an Object-Oriented Application
As any builder will tell you, the most important aspect of a home is not its beauty. Rather, it is
how well the home satisfies the buyer’s wants and needs. The same is true of an OO application.
For an application to fulfill the wants and needs of the user, it is essential for the programmer
to plan the application jointly with the user. It cannot be stressed enough that the only way to
guarantee the success of an application is to actively involve the user in the planning phase. The
steps for planning an OO application You can use a TOE (Task, Object, Event) chart to record the application’s tasks, objects, and
events, which are identified in the first three steps of the planning phase. In the next section, you
will begin completing a TOE chart for the Meyer’s Purple Bakery application. The first step is to
identify the application’s tasks.
Identifying the Application’s Tasks
Realizing that it is essential to involve the user when planning the application, you meet with the
bakery’s manager, Mr. Cortane, to determine his requirements. You ask Mr. Cortane to bring
a sample of the bakery’s current sales receipt. Viewing the
bakery’s current forms and procedures will help you better understand the application you need
to create. You can also use the current form as a guide when designing the user interface.
