First of all, the next source system, because our main trading station server is not in the company, so can not directly from the source system directly extracted data.

一个完备的BI系统有多种Log及监控机制，其中一种监控是监控BI系统存储的增长趋势，BI中所谓的存储可以分为数据仓库的存储跟OLAP数据库的存储。 数据仓库 至少到目前为止，所有的数据仓库还是基于关系型数据库所构建的，只不过数据库的设计遵循了维度数据模型而已。所以我们可以使用SQLServer提供的一系列功能来收集数据仓库中表粒度的存储大小信息，要做到这一点我相信有很多方式，其中一种是使用系统视图： sys.tables返回当前数据库所有的表 sys.partitions返回当前数据库中所有的分区，该视图具有rows属性标明该分区中有多少行数据。我们知道一个表至少含有一个分区，所以我们可以通过前两个视图找到表及其分区，因而也就知道一个表有多少行(当然如果只是为了找到表的行数完全没必要这么麻烦)。 sys.allo

For example, these parameters may have many values, such as thousands, and allow users to select multiple. Also, each of the Pentaho contains a different amount of data, and in some cases can be very l
