Before investing a lot of time and effort in implementing your warehouse database, it is a good idea to validate your model with the user, especially data mart models.
在投入大量时间和精力实现仓库数据库之前，与用户一起验证模型是一个很好的想法，特别是数据集市模型。
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。
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。
