Decision Support System Data To Show The Design And Implementation

With Web technology matured day by day, the application system of Browser/Server structure has already become a kind of brand-new technology because of its advantage easy to maintain and upgrading, and DSS system based on N layers of B/S systems structure will become the main development model with DSS in the future. This paper founded in actual project experience accumulated in developing, recommends a bank DSS datum based on B/S mode to represent the design and realization of the subsystem.This subsystem adopts JSP mode 2 and component designing technology, thus makes the whole system comparatively flexible and having better expansibility, and realizes the separation among expression and the contents well.In web frame design, this paper agrees on the banding regulation between data warehouse object and HTML expression, in order to show on the report form those reflected peculiar information of financial enterprises. in addition, using JSP template mechanism and sealed dynamic Web page layout, makes it can be reused and controlled, structures web design model based on componnent technology, supports software reuse.Structure mode design is the core of web application. Every application program needs flow control on program processing. Request process mechanism on logical expressing layer of web applicantion should control and coordinate the process of multirequest. if dealing with the logically relevant request by way of distribution, may produce a great deal of problems. in this paper we apply JSP mode 2, constitute page dispatch rule, design and implement controller and dispatchor.Through concentrative decision and control, reduces the quantity of imbeded JAVA code among JSP, raises the reusability of logic expressing code in pages.In component-orient design, compound and assemble technique support component reuse. On the basis of a commercial package, with componnent assembly system, realizes the download function of the electronic report form.In the last part, this paper structures the calculation model of the DSS data report form of the bank, designs algorithm metadata, uses a lot of components to realize the data report form.
