生态示范区决策支持系统数据仓库的研究

Study on Data Warehouse in Decision Support System of Ecological Demonstration Zone

随着社会的发展,生态示范区发展越来越快,信息量越来越大,对信息的处理工作也越来越重要,越来越繁杂。20世纪80年代末才起步的数据仓库技术(DW)则与决策支持系统相依相辅,数据仓库技术采用全新的数据组织方式,对大量的原始数据进行各种处理并提取出有用的信息,决策者可以通过分析这些信息从而作出策略性决策。以数据仓库技术如何应用于生态示范区决策支持系统为例,以概念模型、逻辑模型和物理模型的建立为主委内容,并对人机界面的建立以及未来对数据仓库的使用和维护等内容做了阐述。论述了数据仓库系统的设计方法和步骤。论证了在生态示范区决策支持系统中建立数据仓库技术的必要性和可行性。

Ecological demonstration zones are developing rapidly with the development of society, bringing an increasingly larger volume of information. The information treatment is becoming ever more important and complex. Data warehouse technology started only at the end of the eighties in the 20th century and decision support system are dependent on and complementary to each other. Data warehouse technology adopts a totally new data organization mode to carry out various treatments on a large number of raw data and draw the information valuable for making strategic decision. The paper mainly describes the application of data warehouse technology in the decision support system for ecological demonstration zones, highlights the establishment of conceptual model, logical model and physical model, and expatiates the human - machine interface and the future application and maintenance of data warehouse. The paper also describes the design method and prncedure of data warehouse system, and the necessity and feasibility of establishing data warehouse technology in the decision support system for ecological demonstration zones.
