空中交通流量管理数据仓库建模研究

多维数据模型的设计已经成为数据仓库和联机分析处理的核心技术.简单介绍了空中交通流量管理和决策支持系统的特点,对一种四阶段规范化数据建模方法加以改进.新的建模方法通过在建模过程中引入UML的类图,方便了数据仓库组织构架的细化,并且很好地描述了数据仓库的元数据,使该方法更加适于设计面向主题的数据模型.同时指导设计了空中交通流量管理原型系统数据仓库的数据模型.

Research on Data Modeling for Data Warehouse of ATFMS

These years, the design of multidimensional data model has become a key technology in data warehouse and on-line analytical processing area. Features of air traffic management and decision support system are introduced. Then, an improved four-stage standardized modeling method is proposed. The UML class graph is adopted in the new modeling method, which made it more clear to display the whole logic data structure and more convenient to describe the meta-data model of the data warehouse. As a result, this new four-stage method is suitable to reflect the subject-oriented feature of data warehouse. Under the guidance of this method, the data model for data warehouse of Air Traffic Flow Management System (ATFMS) is presented.
