Almost all the Chinese-made goods you see in places like Costco and Wal-Mart are export-only, not available domestically.

好事多（Costco）和沃尔玛（Wal-Mart）里卖的中国制品都是中国专供外销的商品，国内买不到。

Mr Williamson points out that Western companies such as Wal-Mart are already making a success of value-for-money strategies.

威廉姆森指出，西方公司如沃尔玛已经成功实施了物超所值战略。

Since data warehouse and data mart are interchangeable concepts in many situations, it is necessary to specify their definition based on the two-tiered warehouse model.

因为数据仓库和数据集市在许多情形中是可以交换的概念，所以有必要基于两层的仓库模型指定它们的定义。

The data mart tier contains all the data marts, which are subsets of the data repository module, made simple enough for specific groups of end users to use in their data analysis activities.

数据集市层包含所有的数据集市，这些数据集市是数据存储库模块的子集，以便特定的终端用户组在其数据分析活动中使用起来足够简单。

In this model, the business data warehouse is the collection of data repository databases (module), and the data marts are the databases from the data mart tier.

在该模型中，业务数据仓库是数据存储库数据库(模块)的集合，而数据集市则是数据集市层中的数据库。
