Hi Guys, I have a question to ask. I have been using SSAS and Cubes for about a year now. I admit my MDX is not that good but I have been able to plod along and generate reports that are needed. Anyway what I have been leaning against, is using the Cube for simple reports that the user can create in Excel and for complicated reports I use the Data mart. My question (finally!) is this. I have read that you use the cube because the speed of access and that all the data is in one place. But with Power Pivot/Power Query why do I need the cube. These power Excel extensions store the information in memory, so that is the speed issue dealt with. Also having the data in one place would be the Data-mart. Plus SQL is a lot easier than MDX and most of the team know SQL. So why do I need a cube, when I have a Data-mart. I know people will tell me all the fancy things that you can do with the cube. But it is a lot harder than SQL. If I want to do something in the cube I usually have to change the structure of the Fact table. In SQL I just add a field. I honestly don't see a reason why I need to use the cube. Can anyone give me an answer please.
