Bank Of Dss Based On Component Technology, And Realization

A bank decision support system based on the component technique is proposed in this paper. In the system, it is required that the data can be merged, extracted and transferred according to the original knowledge, so that the functions of relevant information querying, statistics collecting and analyzing, decision supporting, works monitoring, and operation evaluating etc can be implemented, by which the managers at all levels in the bank can understand the dynamic situations of the corporation at any moment, and thus enhance the management and make a correct decision.The paper first introduces the background knowledge, application perspective and current available developing technologies of the Decision Support System, and then defines the design goal and functional requirements of the Bank Decision Support System.Next, after the argument of the three-layer architecture based on B/S, the DSS' Framework based on Web and Component technology is brought forward, and then each layer is designed and implemented respectively. In the representation layer, the general functions in web page are abstracted, to form the general Web components. Since the kernel of DSS is the modeling technique, the core business logic is realized through the design of Component model organizer, by combining the modeling technique and component technique. In the database layer, a data warehouse based on relational storage mechanism is used.After that, the design and implementation of the DSS model based on the component technique are introduced in details, including the structure of the Component model organizer, the definition, storage and organization of component models, as well as the methods of building the atomic models and constructing the compound models through atomic models. The encapsulation of the implementation of DSS'model fully embody the flexibility, reusability and expansibility of the system.In the section of critical techniques, the formula library technique designed according to the specific bank business is introduced, by which the adscription of the tree-form accounting subjects can be well organized.Data buffer is used in the general page producing technique, to improve the response speed of client. Database manager is applied to perform a uniform management on the database access operations and mask the complex database operations for the business logic components. Likewise, the performance of database access is improved by means of the buffer pool and operation estimation module.
