The Practice And Research Of Constructing Budget Management System With Smart Client Technology

At present, the thin client architectural applications based on web browser and service are being widely paid attention to by people. And it increases dramatically. The thin client architectural is usually called B/S architectural. With the advantages of deployment, centralism management and maintenance, it has substituted the position of rich client architectural, which had been massively developed in the mid-1990s.Despite the impressive characteristics of the thin architectural, it has limitations. Firstly, it can't take advantage of the local hardware. All the responses and calculation work must be done by the server, which makes too much pressure to the server and the network. Secondly, it can't provide users with a rich and responsive user interface, and some commonly used functions by rich clients cannot be provided for the users. Thirdly, each time users need to send out the processing requests of their operation and clicks to the server, and the browser must wait for the response's arrival, till then user can continue. So the response speed is much too slow. However, all of these are actually the merits of the rich client architectural application. The rich client architectural application can make good use of the local hardware resources and the features of the client operating system platform. It also can provide users with a rich and responsive user interface. So the smart client just unifies the rich client and the web. It combines the rich client's merits with the thin client's deployment and the manageability merits and avoids their disadvantages.These characteristics of the smart client are very suitable for "Budget Management System" which is an enterprise level application for a large andcrossing region enterprise. The budget management refers to taking the goal profit as the guide, implementing the comprehensive budget of an enterprise's entire managements. Through establishing comprehensive management, the cost expense, the fund and the debt budgets, and carrying out the comprehensive budget forecast, the budget establishment, the budget adjustment, the budget use control, the management analysis, the effective tube system is established with the profit and the cost as its central inspection controls.The functions of this application are complex. In order to adapt to Chinese's report form and the operation custom, the application must provide users with a rich and responsive user interface. At the same time this application, logically, is a whole, but in the distribution, actually, it is the crossing region distribution in many places. It's possible that its client and service connect through the Internet, which requests providing rich operation contact surface. For example, the obtained report form editor, operations of restore and cancellation are available, and so on. It requests providing non-touch deployment and automatic updates, providing the fast response speed and editing the report on wireless. It also calls for taking advantage of the local hardware resources and software resource, such as printer and Microsoft office. The smart client application can take advantage of the local resources, connect network resources, support offline capable, and provide non-touch deployment and automatic updates to meet these needs.
