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,

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

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

NET. With the freeze of mdx1.1, the expected mdx2/. NET 2.0 to mdx10/d3d10 roadmap has been annihilated with the cancellation of the mdx2 project. Apparently, Microsoft does not want MDX to take the lead in xNa, but xbox360 is the main

This and previous periods are often compared in a report query, such as March sales and February sales. Generally there are absolute and relative value points, If this period increment = Current period value-the value of the previous period; Current Period increase = (current period value-previous value)/current period value; relative value 1:MDX this query With member [Time2].

I wrote an article about summarizing and aggregating this parent-child relationship in SSRS development (SSRS series-Using the group group attribute to implement a summary report based on parent-child recursion), the query in the example is based on the SQL Server relational database, which is based on the MDX parent-child dimension SSRS report.
