A Research On Development Techniques And Application Of N-Tier Systems For Enterprise Solutions

With the rapid developing of information technology, the architecture of system development is paid more and more attention. The traditional developing method based on single-tier system is gradually changing to the one based on multi-tier distributed system, especially applying in enterprise. Its hugeness *, complexity and levity make the system developing great difficult, which is solved by the development technology of the architecture of multi-tiers system. And the technology also makes the development easier , at the same time ,the system can be more easily maintained. It is more importance to research on the developing technology of the multi-tier system for improving the level of the applied software oriented enterprise.This paper does some research on the developing technology of the N-tier enterprise-objected system and applies this technology to one enterprise. It studied the development and application of the enterprise-objected N-Tier Architecture of system, and illuminated how to develop the applied software system using CORBA, EJB, COM. Also in this paper we can learn some modified schemes for developing system.The method put forward in this paper adopts uniform model-establishing language UML as well as the object-oriented analysis method and the developing technology using components, so it has some priority and extending applied value.
