数据仓库中的多维数据模型及其对象关系的实现

Multidimensional Data Model in Data Warehouse and the Realization Based on ORDBMS

数据仓库和联机分析处理（OLAP）是当今商业数据处理领域的研究重点。传统的关系数据库技术已经很难满足联机分析处理对数据仓库的大量数据进行分析查询的要求。多维数据模型已成为数据仓库和联机分析处理的核心技术。该文设计了一种直观、有效的多维数据模型并给出了基于对象关系的实现。

Data warehouse and on-line analytical processing(OLAP) are the research emphases in the business data processing area. The traditional technology of relational database can not meet the need that on-line analytical processing analyses and inquires a great deal of data in data warehouse. Multidimensional date model has been the important technology of date warehouse and on-line analytical processing. This paper proposes a straight and effective data model and the realization based on ORDBMS.
