很多搞过数据仓库的朋友曾经问我有没有数据模型的资料,很惭愧,一来是实施项目确实不多;二来就算有也是公司机密的东西,不便泄露;今天登陆到inmon的网站,刚好看到这方面的资料,于是就当了下来,也算为自己留个底,为以后的项目做个参考。

List of available data models:

以下为可用的数据模型列表:

Description:

描述:

The corporate data model is the intellectual road map for the development of the data warehouse. By creating the data model, the developer understands how the many and complex parts of the data warehouse have to relate.

企业数据模型是数据仓库开发的一个路标。通过创建数据模型,开发人员就能够理解数据仓库最多和最复杂的部分必须涉及的。

The corporate data model is the secret to being able to build the data warehouse iteratively. The first development effort uses one part of the corporate data model. The next development effort uses another part of the corporate data model. The next yet another part of the corporate data model. In such a manner, the different development efforts are linked together in an integrated and cohesive manner.

企业数据模型是如何迭代建立数据仓库的关键。第一轮开发的目标是创建企业数据模型的一部分;在接下来的开发目标是创建的另一部分企业数据模型;下一轮依旧是一部分企业数据模型。以这样的方式,不同的开发目标以综合性和凝聚力的方式就联系在一起了。

The corporate data model consists of three levels:

企业数据模型包含以下三个层次:

  • the high level data model, or the ER diagram,
  • 高层数据模型,或者ER关系图
  • the mid level data model, and
  • 中层数据模型
  • the low level data model.
  • 低层数据模型

For a complete description of the techniques of data modeling for the data warehouse environment please refer to INFORMATION SYSTEMS ARCHITECTURE - DEVELOPMENT FOR THE 90'S, John Wiley.

如果需要完整数据仓库环境的数据模型技术描述,请参阅《信息系统架构开发》90年代,John Wiley

The different levels of modeling relate to each other in a natural fashion. To use an analogy, the different levels of modeling are like:

不同层次的数据建模以一种很自然的方式联系在一起。例如,不同层次的模型可能是这样的:

Just as the globe relates to the US, and the map of the US relates to Dallas, Texas, so do the high level, mid level, and low level models relate to each other.

正如全球与美国相关,而美国地图又与克萨斯州的达拉斯相关一样,所以高层、中层、低层数据模型也是相关的。

Issues:

问题:

One of the primary issues of the process of data modeling is whether the data model must be built in its entirety before any development can occur. In truth only the high level data model must be completely developed. The levels lower than the high level can be developed in accordance with the subsets of data that are developed as part of the iterations of development. Indeed, it is not good practice to develop the data model in its entirety to the lowest level of modeling before the warehouse is built.

数据模型过程的一个主要问题是数据模型必须完全建立在其整个开发过程之前。事实上只有高层次别数据模型必须完全开发。稍低层次的模型要依据于迭代开发之后的数据。事实上,在数据仓库构建之前,直接开发底层数据模型不是最佳办法。
