  Junk Dimensions with no Loading Needed

  When you are working with dimensional modeling there are some situations where several dimensional attributes don’t make since to be in any other dimension. When this occurs you can combine them into one dimension call a Junk Dimension. In this example yo

  SSAS Different Dimension Granularity

  In an SSAS cube you sometimes need to connect a dimension at a different granularity than other dimensions. For example, if you have budget measures and actual numbers. If you are trying to budget your expenses you budget at a higher level than the actual

  How to create Day,Month,yearwise Cube in SSAS

  Well, there is a lot of concepts that you should take in consideration. 1st of all, you will need a fact table. In this table you should have a day code. This day code typically has YYYYMMDD format so it can be a integer and benefict from many advantages.

  For small dimensions it is usable (the standard SCD), but for slightly bigger dimensions it slows down the package because it doesn't use cache. Here are some alternatives . You can support a request to improve performance at Microsoft .
