ve implementation of client / server (client / server) programs. Dynamic Data Exchange (DDE) Using Dynamic Data Exchange (Dynamic Data Exchange) technology, an application can dynamically link the data to another application, so that two pletely different applications, establish a dynamic data link. When the original data changes, you can automatically update the linked data. Visual Basic provides the programming dynamic data exchange technology, the application program with other Windows applications to create dynamic data exchange between different applications to municate. Object Linking and Embedding (OLE) Object Linking and Embedding (OLE) to each application as an object (object), to link different objects (link) up, and then embedded (embed) an application, which can be a sound, image, image, animation, text and other information collection style technology is Microsoft39。 s strategic corporate object technology, which the multiple applications into one, as each application for an object linking and embedding, is an application integration technology. Using OLE technology, you can easily build posite documents (pound document), this document from a number of different application objects, each object in the document and linked to the original application, and perform with the original application the same operation. Dynamic link library (DLL) Visual Basic is an advanced programming language, do not have lowlevel language functions, the operation of the access to the machine hardware is not easy to implement. But it could be dynamic link library technology will C / C + + or assembly language programs to Visual Basic applications, you can call the same function as the internal call functions written in other languages. In addition, the dynamic link library, you can call the Windows application program interface (API) function has the function to achieve SDK. systems research and feasibility analysis Research Before the formal development of management information system is necessary for research, the need for mainly the following aspects. (1) to the user39。 s request to conduct a feasibility analysis of the survey results confirm the feasibility of system development. (2) The staff of the new system not all systems researchers, some people process data for its function and no clear understanding of the method. They only work according 共 13 页 第 5 页 to their business needs requests, system developers to conduct a detailed survey and analysis to confirm the user39。 s requirements can be achieved through the existing puter technology to ensure the development of management information system functions and user submitted required match. (3) the existing business system may be a manual system, it could be used and the puter system, no matter the circumstances, the current system should be investigated in detail the specific circumstances of information processing, functional structure within the system in order to design a reasonable, good new system logic model for the design of the new system to lay the foundation to ensure the quality of the entire system development. In short, the current system is necessary to conduct a detailed investigation, a clear user needs, to ensure the development of new system functions consistent with the user39。 s requirements and avoid a lot of manpower, material and financial resources, the development of the new system is the failure of the tragedy. Overview of Feasibility Study Feasibility analysis is the user39。 s requirements and system on the basis of research conducted on the development of new systems of social, technical, economic, management, analysis and development of new systems e feasible, not feasible, need to modify , additional investment, the suspension of development, step by step and other programs and conclusions, and finally plete the feasibility analysis. Feasibility analysis of the general can be defined as: a feasibility analysis early in the construction of a project study and appraisal of the proposed project to conduct a prehensive and integrated technical and economic capacity of the investigation to determine whether it is feasible. (1) the feasibility study stage of the work include the following: Objective analysis of whether the new system status and business development n。
