The Research Of Metasynthesis Integration Method On Large Scale Information Systems And Their Application

This dissertation mainly studies the establishment of integration information system (IIS) of an enterprise organization in which some information systems have been built up and applied, only playing a limited role in few sections and not having a great effect on the organization itself. A trend has been formed about the research and development of information system in close combination with the enterprise organization, such as the electronic commerce system (ECS). It is very important to study and establish IIS suitable for the enterprise organization shortly before China joining WTO.Special emphasis of this dissertation is laid on the following aspects.1. Study on the methodology of IIS.One of the reasons the past researches into integrated systems are not satisfying is due to the methodology. The author analyzes and evaluates the application areas, merits and limitations of some well-known methods, pointing out that some of them are unfit to be easily used in the development of integrated systems and have to be integrated. The author also makes an investigation into a mixed method composed of the given simple ones, putting forward an integrated structure model for exploiting the integrated information system.2. Study on the enterprise information architecture (EIA) and on the architecture of IIS.The author studies EIA aiming at the integration and introduces the concept of enterprise environment based on the seven-hierarchy theory of an information system with wide social nurture. The author offers a new architecture model of the relation between hierarchy and IIS by means of one-to-one three-tier Client/Server, information architecture (IA) and integration hierarchy.3. Study mainly on the design of IIS.The author designs a three-dimension wavefront requirement integrated model— a prerequisite that makes the development of IIS more comprehensive, reliable and...
