function of the data table can be realized. In the mobile window can easily move the historical data out, add new data, so that the size of the table is basically stable. In addition, the design of the table does not need to be very normalized. A certain field redundancy can increase the efficiency of the SQL statement, reduce the number of joins, and increase the execution speed of the statement. 3) separate OLAP and OLTP modules The statements f

When using IMPDP to complete the database import, if the table already exists, there are four kinds of processing methods: 1) Skip: Default action 2) Replace: Drop table First, then create TABLE, and finally insert data 3) Append: Add data based on the original data 4) Truncate: Truncate first, then insert data 2 Preparation of the experiment 2.1 SYS user

Data mining is one of the most exciting new features of SQL Server . I view data mining as a process that automates the analysis of data to obtain relevant information, and data mining can be integrated with either relational or OLAP data sources, but the benefits of integration with OLAP are extremely significant. Because the structured data source makes the user no longer need to provide the massive infor

Except those who do not know what paging is, most people think of a word called LIMIT. Unfortunately, DB2 does not support this keyword, so how do I write the DB2 paging query? As long as you have learned OLAP functions, paging query is very simple. Even if you do not use OLAP functions, follow the following SQL Except those who do not know what paging is, most people think of a word called LIMIT. Unfortuna

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.allocation_units返回所有的分配单元，分配单元具有很多关于数据页的信息，其中一个属性石total_pages，它标示该分配单元总共有多少个数据页面。一个分区具有一个或多个分配
