Based On The Software Architecture Of The Layering Mode Used In Hitachi ERP System Project

With the sharpening constantly of crisis of the software, people realize the importance of the software architecture, and think the software architecture, deep research is it raise software productivity and solve software maintain new most hopeful way of problem to become. This text combines the design and development of Hitachi ERP subsystem project that Chang Chun University of Science and Technology and Hitachi medical treatment develop jointly, analyses and summarize to the commonly used software system structure now. Propose according with the points of software development modes of the scientific research institutions, such as small and medium enterprise and university , etc. in the article, to divide layers of the software architecture carry on network analysis , is it divide layers of the software architecture to prove, and carry on detailed analysis to Hitachi ERP subsystem data design and realization on story mainly, point out that the design on story of data replies the function while using in the software , provide one kind of definitions of layer of data and relation between one kind of levels. The research of this text hopes to play a certain reference arriving role to the software development and design of the university, scientific research institutions and small or medium enterprise.
