Middle Office Restrictions For E-Commerce Systems

Abstract

E-commerce systems may be considered as 3-layers information logical structure consistent of front office, middle office and back office layers. Front office is the best described layer of the model. It is related to direct information exchange between the client and hardcore part of the organization. The back office related to LAN information exchange and physical realization of front office demands is also well matured. But there is one important problem: all front office applications are stateless type (after cancelling the session, all data are lost), whereas back office applications are real time with necessity of blocking records, generation of online fiscal documents, etc. Any model of a-business defines its own supply chain. A linkage between logical layers and the defined supply chain is forming by modules and functions of the middle office layer. This layer limits full operational ability of the e-commerce systems like, ZenCart. The main problems derive from the computerization and integration of the supply chain. The offered solutions for the middle office layer are usually either too complicated or improper for online integration. Therefore for successful rolling out of computer aided e-commerce system, the optimum structure of the middle office layer design is crucial, because there are the most important conceptual limits.
