数据仓库概念模型的设计

Design the Data Warehouse Conceptual Models

要设计一个能够正确反映用户的需求 ,又能够使用户易于理解的数据仓库概念模型是一项不同于传统事务处理系统概念模式设计的重要工作 .文章提出了一个类似于传统事务的 ER模型的 DWER模型 ,给出了对 DWER模型的评价 ,并与其它相关的模型进行了比较 。

Data warehouse conceptual model should be able to reflect the users requirements accurately and should be understandable. Designing such a model is very important and completely different from those adopted for operational systems. Similar to the ER model, We construct a data warehouse model -DWER model. We present an evaluation of the model and a comparison with other existing model. Finally, we describe the model using logic description.
