Welcome to Apache™ Hadoop™!
The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using a simple programming model. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-avaiability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-availabile service on top of a cluster of computers, each of which may be prone to failures.
Error in SSAS Cube pivot table when creating custom groups - SSAS 2008, Excel 2007
Hi, We have found an extrange behaviour when grouping some dimension members , in an Excel 2007 pivot table connected to a SSAS 2008 perspective. 2.Grouping members together « Chris Webb's BI Blog
One of the weaknesses of Analysis Services, in my opinion, is support for creating custom groupings of members. I reckon that 90% of all calculated members on non-measures dimensions must be doing just this, ie just doing an AGGREGATE or SUM over a set of members, and yes calculated members will return the right values but my complaint is something else. It’s that you then have no idea what members were aggregated together inside this calculated member, and that functions like VISUALTOTALS, NONEMPTYCROSSJOIN etc that you would like to be ‘group aware’ of course aren’t. Some examples needed, I think…

Most business users of the data warehouse/business intelligence system are content with looking at their information in one of two ways: by the current state of affairs, or by tracking history. For example, a sales manager developing a sales forecast wants to see sales for his or her region as that region is defined today. But that same sales manager confirming the compensation plan must correctly associate all sales with each salesperson, even if they used to report into a different region. Today's best-practice BI systems are designed for these alternative approaches. But sometimes it's more complicated than that. Do our existing design techniques enable a business user to restate history as of an arbitrary date?
