Study On The Conversion From C/S To B/S Mode Based On Management System Of Enterprise Document Work

With the rapid development of computer software and hardware technology, the computer system has gone through a simple to complex, low to high proceed. Computing mode also experienced host batch mode, host mode dumb terminal, network-centric mode, C / S mode, and B / S mode. C / S mode is known of the client and server architecture. It uses the advantages of server-side and client hardware environment, to assigne to the Client and Server to achieve, and it willt reduce the communication cost system. At present, most of the application software systems are Client / Server model of a two-tier structure.With the size of the enterprise application and the increasing complexity of applications ,C / S mode of the shortcomings have been exposed and more obvious. The client's upgrade and maintenance become more difficult because C / S structure of each client must be installed and configured. In order to solve a series of problems which are brought about by C / S structure, in recent years, with the rapid development of Web technology, the emergence of a new generation of computing model-B / S model came out. B / S model simplifies the C / S of the client, and the client can be fitted with the operating system, networking protocol software and browser. While the server-side focus on the application of logic, development, maintenance, and most of all the work has focused on the server side. Because of under the B / S structure, it is only to need to develop server-side applications without the client and server-side applications can run on the client through WEB browser. Therefor, according to the specific business requirements, we need to develop a technology to find a conversion method from the C / S to B / S mode.In order to find conversion methods, it is necessary to master the key technology. First of all, you should know the object's development methods—to guide the object-oriented programming software for the development of the norms. Second, to understand the basic unit for the Component Object Model - COM and understand between the COM components, COM objects and COM interfaces's relationship, and these are the basic of Active X technology. Next, to understand Active X technology - built on the OLE and COM technology's basis of the inheritance and development. Active X technology is not only able to use the Internet on-line, but also more widely used in a wide variety of programming languages such as Delphi and Object-oriented development tools. To understand the Active X controls, the creation of Active X controls, and the usage of Active X control and then focus on understanding IntraWeb technology to high-speed easily to create Internet, Intranet and Extranet applications, and to talk about the technology of IntraWeb - IntraWeb the technical characteristics, the working principle, development mode and so on. Finally, to research every step of the transplant changes in the level of attention and allocation of development environment to put up a conversion proposala from C / S model to the B / S mode.According to the proposal first 1 should analyze the structure of C / S model and B / S model, sorted out the C / S model and B / S model between the corresponding advantages and disadvantages. For the actual situation to use the form of Software Reuse which are major source Reuse code, object code reuse and reusable components. And then to analyze the structure of the application on B / S model. Then to set three applications the client, application server, database server structure into WEB server. It is the biggest difference with the C / S model structure as well the key to transplantation. And then from the COM component to analysis and hierarchical abstract, to determine COM components, creating COM interfaces to complete the definition of components for the assessment and verification of logic. ActiveX will further combine IntraWeb with technology. The main framework will be accomplished by IntraWeb, for the realization of ActiveForm is achieved by the complex function modules. Then we will build C / S and B / S mode architecture migration. There are concrete steps to set up Web servers, software reconstruction, ActiveX generation space, call control, system integration. Further to explore the process of ActiveForm technology, and to analysis IntraWeb framework for the migration methods.According to the above-mentioned methods, from the practical needs of the project, I have to use the combination of official business workflow management system, "Trade and Industry Management System 4.0" designed to achieve. First of all, from the C / S model legacy systems to analysis and sort out the main features of the module reconstruct system of functional software. Using ActiveForm and IntraWeb technology to achieve the migration of the enterprise document workflow management system from C / S model to B / S mode, as far as possible to use the original code, and issue the conversion systems on the Web server . The specific process are rebuild, achieve attributes, and methods; registration, test and release. After accomplishing the two modules of information processing sub-system users and processing subsystem of the document transfer. Finally, I need to complete the relocation of the functions to achieve a system by C / S model to the B / S mode of transfer. Thus, successful achieved the expectable purpose.Due to the increasingly complex documents and diversification, especially for those people who have to deal with a large number of business documents every day, the preparation of documents becomes a further study content, whether or not can we design a set of documents report designer to quickly and accurately produce the official statements, is the main contents of the study today. In the course of the office automation documents, the design process is alao crucial, how to make users to definite the enterprise workflow is the main content to further study.
