Presentation
Advantages in Developing Enterprise Architecture by Using Object-Oriented Methodology
Currently enterprise architecture models being developed by Architects to describe the customers’ problem use the Functional/Structured representation while software designers implementing the systems use the Object-Oriented representation. The architect must satisfy both architecture customers. One approach is to use the Object-Oriented representation in developing the architecture design. A benefit in using the Object-Oriented representation is that it closely matches the customers’ view of the problem world; which consists of objects that perform actions and utilize information. Another benefit is that its use has promise in providing a common representation for all architecture customers in developing models that are usable by the enterprise Customer, Users, Designers, and Software and Hardware Developers. Thus the use of Object Oriented Methodology is an approach that can satisfy all customers of the architecture and its products.
