but not confirm

While selecting objects, the following considerations should be kept in mind for a simpler (and better) object model.
1. Every object that you put in your object model should have some responsibility or role to play in the problem domain. You need to know each object, its attributes, and services. If there is no way to know about the object, remove it from the object model.
2. Avoid having controller objects because controllers usually end up with functionality that’s better done by other objects themselves, making the message passing more complicated, and resulting in higher coupling. Use delegation instead. Note the difference between controlling and delegation; a controller wants to do every thing by himself (doesn’t trust anyone), while a good manager delegates responsibility (and takes credit).
3. In large systems several objects are likely to have similar or even identical responsibilities. Look for such objects and seek a common name to simplify the object model.
4. Use meaningful class names, names that describe objects in that class. Try to use names from the domain vocabulary to avoid confusion.

An object model of a system captures the static structure of a system by showing the objects in the systems, their relationships, their attributes, and their services. To stream line the derivation of the object model, Peter Coad has divided the process into 5 activities, each being further subdivided into a number of steps. Following is the description of these activities.
