MDX is mainly used in OLAP query language, full name: Multi-dimensional Expression. Syntax is similar to the Structured Query language SQL for OLTP, but there is a big difference. Look at the Sql-server online Help, combined with the company's existing OLAP implementation, a simple study.1: The Concept: Hierarchical structureFor a few other concepts: dimensions, levels, members, attributes are better understood, only the concept of hierarchy, the begi

Not long ago, after the "Report on the BI System of Shanghai Jiao Tong University, an elite forum for informatization practitioners in 2011 Colleges and Universities" was released, several friends asked questions about data presentation, see the importance of data visualization in BI projects. One of them was a friend of Emmy who asked how FusionChart presented the result data after MDX query and asked this question in his blog. For details, see here.

Based on the Data Warehouse SSRS report display, can generally directly through the SQL query, stored procedures, views or tables and other ways to load the data and present in the report. However, if you are based on a cube's data query, you can no longer use SQL syntax and should use MDX queries. For articles on MDX and other SSRS, see the BI Series Essays list (SSIS, SSRS, SSAS,

Yesterday I sent a translation of an article, it is said that there are existing algorithms exist, yes, I would like to remind, I am not a highly skilled scholar, or a so-and-so researcher, then my algorithm how to come, some people said that the world article a big copy, see you will copy will not copy, do not know whether you have been to those papers site , did not go there to find any papers, anyway, I often go, you go to you will find that many of their algorithms are others have done, have

clustering. I'm not quite sure how these two algorithms relate to relational analysis. In the next few days, I spent my time in finding and reading data mining and correlation analysis (a bit of a waste, but the boss didn't want to pay for a veteran to do the project, no way to touch a stone River). This day, I finally put down the data mining books, re-open the as Help document, while reading the MDX section, while in the homemade
