Studying the deficiencies and problems of different architecture in developing distributed systems and analyze the existing solution

In this paper, we examine and compare various aspects of the three proposed architectures in producing and the development of distributed software. We are discussed about the need to create an ideal model for an optimal architecture studying the aggregation problem that the architectures are not responsive. We are supposed to reach some results such as: which is the best and completely software architecture for enterprise resource planning that have enough flexibility, exchangeability, reliability and usability.
