Since the beginning of the 21st century, with the development of information technology and high-speed expansion of the amount of information, as well as the rapid development of the Internet and the popularity of the rise of the tide of e-commerce, igniting the fire of the demand for Internet-based distributed applications . The traditional Client / Server application architecture can no longer meet the needs of this new application. How the computers on the network organization and coordination of work, the formation of the huge potential of distributed and parallel environment, so that different programs on different machines can interact, the development of large and complex distributed enterprise applications has become The focus of the development. This paper analyzes the characteristics and shortcomings of the currently popular distributed object technology, COM services provided based on the idea of ??Windows DNA application of the three-tier architecture, proposed a new architecture for building distributed Web applications - based on COM distributed Web applications. This architecture gives the development of Web-based applications in a distributed computing environment, a new, flexible and viable solutions. DNA three-tier solutions based on Web technologies and COM as the core, an enterprise application into three levels of abstraction from the logical architecture: presentation layer, business logic, and data services layer, and given to SOAP as a tool to achieve cross-network, cross-system, the components of other applications access to the network of inter-object model. LAN inherent on the same platform development components developed for heterogeneous platforms on the LAN-based applications and LAN components based distributed component-based applications, system applications COM application; application, the system uses the SOAP access to their. This article discusses the system model of distributed Web applications, including: the structure of the system model, indicate and distribution of works and technical characteristics. In addition, a detailed analysis of enterprise management information system and its technical development and status based on the study of flexible production management information system construction method, flexible user-oriented flexible for developers and faces flexible flexible form of flexible management information system and flexible management information system architecture, and construction method from these three levels of enterprise asset management system, to achieve superior performance, good scalability maintainability management information system to lay a theoretical foundation.
