次に階層化の観点で言うと、オブジェクト指向設計手法の場合はボトムアップ

Then say in terms of hierarchical, object-oriented design method for builds a system to bottom-up. For example, vending machines here, each object three roles to work with each other, to work, so the individual object to reuse and leverage its role in development of other systems easier.

The next time you say in terms of hierarchy, in the case of object-oriented design techniques to build the system from the bottom up. For example, in the example of the vending machine, three objects have their roles, since it operates in another cooperation is easy to re-use by utilizing its role in other system development individual objects will be.

Next, in view of the hierarchy of the object oriented design method to build up the system. For example, in the example of the vending machine, each of the three roles and objects, so as to operate with each other, each object makes it easy to any other system development, its role is to reuse.
