Not too long ago my boss Yaniv got a telephone from one of our customers saying that he thought a cube was missing some values from it. The thing is that at first that didn't sound logical to us because usually we would get an error on that. We expected the process of the cube to fail, or something of that sort. But not this time. Now, there's a few reasons why there are rows missing from a cube as recently blogged by Richard Lees. But our reason was slightly different. We were using a view...
If you're following this blog, then you know that Sunday, May 30 th 2010, I went to the SQL & BI Data Platform convention held in Tel Aviv. Specifically, I went to Mr. Donald Farmer 's seminar on Data Integration in Large Organizations . I did live blogging from most of the event, though actually, I didn't manage to blog about the last part of it, because I was preparing for something that was pretty big for me.... I'll start over. When I first heard Mr. Farmer was coming to lecture...
Slowly Changing Dimension Type 2 Tips & Tricks I've blogged in the past about Slowly Changing Dimension Type 2 , and I see that it's a subject that really interests you. I remember quite distinctly how hard and demanding it was to create it for my project (trust me I do!) and even to do it for two business entities. So, hoping that I may assist you even slightly, I thought I may share with you a few thoughts I have on the matter: Do you really need it? Now I know this is going to sound...
Creating a Report Model based on an Analysis Cube – Pros and Cons If you follow my blog, you probably know by now that I developed a report model based on the Analysis Services cube I already had. I even got around to updating the report model . And then, my users started using it. And you know, whatever we do just seems so wonderful to us, until our users find all sorts of flaws with what we did… so yes, my users did open my eyes to quite a few problems that may occur when you build...
Well I guess congratulations are in order because I finally got around to using a report builder in my project. Turns out that building a report model based on a cube is as easy as 1-2-3. Still I had a problem, as for some unknown reason the translations were showing for my dimension names and my measures, but not for the dimension's attributes... At first I thought maybe this is a problem solved by Service Pack 2 (as my tests were done on a Server with Service Pack 1). Alas, no. So, a further...
A Parent - Child Dimension is a special sort of dimension, to be used in case: You have data even for non – leaf members. For instance, you may have set – up costs allocated for the Category level (the higher level), but profit data for your Product level (the lower level). You have an unbalanced hierarchy. The classic example for this might be the Geographical Hierarchy which at times might look like: Country > State > City, and at other times like Country > City. For an international company...
Panorama Nova View Analytics is a viewer on a cube which enables you to drag and drop attributes and measures onto a grid, so as to study the influences different slicers and dicers have on a measure. Each combination of slicers and dicers with a certain measure, can be saved as a presentation (the name in Panorama for a dynamic report). The presentation is dynamic, as you can change not only the filters on the existing attributes (as in Reporting Services), but also add new attributes and remove...
…like for instance, it could all of a sudden turn into a ball! J Ok bad computing joke. So this time around I thought I'd tell you about a weird incident I had with my cube. I found out I could see my cube in the Management Studio and even browse it, but when trying to run an MDX on it (again, in the Management Studio) it would tell me I didn't have any cubes for the MDX to run on.. I could still run MDX scripts on it in my SSAS project so I continued as usual, thinking to myself only that this is...
We define names for our tables and columns following the guidelines defined in our company. we might even adhere to international naming conventions. Still, nothing promises us the names we give our DB objects will be comprehensible to our customers. And this is where SSAS steps in - Analysis Services enables you to give alternative names to your dimension attributes in the following two ways: Translations may be given to: dimensions, dimension attributes, user hierarchies, measures, measure groups...
