The developments of various large-scale enterprise information systems often need to invest a lot of time, a lot of manpower, material and financial resources. It is important to understand the common of large-scale enterprise information systems and develop appropriate application software framework which can improve the quality of large-scale enterprise information systems and shorten the development cycle in the future. At present, many enterprises have paid more and more attentions to the study of the application framework for a domain, which can guide the development of a variety of similar systems in the domain, thus has very high research value.Large-scale enterprises usually have the tree-form organization, and large-scale enterprise information systems also have significant features and common characteristics, in addition to the need for flexible access control at all levels of units, the interaction between the upper and lower units is often accompanied by data collection and distribution. In order to understand the overall situation of enterprises, higher level units often need to collect and aggregate data from lower level units, therefore, data collection is bottom-up and data distribution is top-down.In order to improve the quality of large-scale enterprise information systems and shorten the development time, this paper gives researches on the application software framework for the rapid development of the enterprise information systems.The research methods of framework include the systematic method and the practice method. This paper uses the practice methods, and choices several existing large-scale enterprise application systems that belong to the domain of Information Collection and Distribution of Large Enterprise. Combining domain engineering, through domain analysis and design, a framework of Information Collection and Dissemination of Large Enterprise System is constructed based on.Net platform. Datang audit integrated information management system is used to test and verify this framework. For the new developed Web applications used by multi-level units, the application of the framework can achieve rapid development, productivity and quality improvement.
