【摘要】 本文所介绍的基于组件技术的银行决策支持系统要求在原有的银行业务数据基础之上，进行数据总汇、抽取以及转换，从而实现相关的信息查询、统计分析、决策支持、工作监督、业绩考核等功能，使各级银行管理人员能随时掌握动态经营状况以便加强管理和作出正确的决策。 论文首先介绍了决策支持系统的相关背景知识、发展现状和目前流行的开发技术，确定了银行DSS的设计目标和功能要求。 接着进行了基于B／S的三层体系结构的方案论证，提出了基于web和组件技术的DSS系统框架，随后分别对各层进行了设计与实现。在进行表示层设计时，将web页面的通用功能抽象出来形成通用Web组件。由于决策支持系统是以模型技术为核心的，因此我们把组件技术与模型技术相结合，设计了组件模型管理器来实现系统的核心业务逻辑。数据库层采用了基于关系型存储的数据仓库。 然后介绍了基于组件技术的DSS模型的设计与实现，具体阐述了组件模型设计思想和实现步骤，包括组件模型管理器的结构，组件模型的定义、存储、组织，以及原子组件模型的制作和如何通过使用原子模型来构造复合模型。以组件的方式封装银行DSS模型的实现能充分体现系统的灵活性、可重用性和可扩展性。 在关键技术中介绍了根据具体的银行业务而设计的公式库技术来实现对树型会计科目归属的管理。通用页面数据生成技术充分利用数据缓存来提高系统对客户端的响应速度。数据库管理器对数据库访问操作进行统一管理，为业务逻辑组件屏蔽了复杂的数据库操作，同时缓冲池管理和操作评价模块也提高了对数据库的访问性能。更多还原

【Abstract】 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.更多还原
