摘要
数据集市作为新兴的数据管理技术 ,与数据仓库相比具有很多优势 ,被广泛采用在各种应用系统中 .但目前的数据集市系统尚不具备跨主题的信息查询能力 ,无法为用户同时提供多个领域的信息或全局性的数据 .本文针对这一问题 ,提出了数据集市指标映射方法 ,并给出采用这种方法的数据集市系统的结构描述以及相应的联机分析算法 ,为问题的解决提供了一种可行方案 .
Data mart is a new kind of database technology. Compared with data warehouse, it has many advantages, so it's widely adopted in application systems. But one shortcoming of Data Mart is that it can't provide information across several categories simultaneously. In this paper, in order to solve this problem, a method called 'index mapping' is put forward, and new architecture and OLAP algorithm for Data Marts is given out.
