Abstract

In this research, after a brief introduction, different information systems, classification of various methodologies, Object –Oriented view and methodology will be discussed in detail. Then we will design a mechanized information system for purchase activities (including domestic and international purchase). The purchase division of one of the leading automakers (Sazeh Ghostar Saipa Company) was selected for the case study. The division is a good example of a purchase system because of the nature of its activity which is engineering design as well as provision of the parts.
At end of this article, using a questionnaire, Object-Oriented Methodology will be compared to Structured Methodology (SSADM) from technical, usage, and management points of view and then the results will be analyzed.
