In Part 1 of this tip series, I talked about a typical SSAS application architecture and different components of the SSAS internal architecture. A cube dimension in SSAS is an instance of a database dimension within a cube. But nevertheless, you can query the cube meta data. And extended as it grows. 2) Dimensions: Dimensions are of two types from a SSAS Multidimensional Data Model perspective – Database dimension and Cube dimension. During this process, SSAS reads the source data, applies any transformations or aggregations, and organizes the data into a structure optimized for querying. . I also talked about roles for different components and areas for performance improvement. SSAS 3 fact tables The SQL understood by Analysis Services is limited: There are no joins possible, and the WHERE condition may only contain clauses like [HIERARCHY_UNIQUE_NAME] = '[Date]. Commented Nov 30, 2015 at These reusable dimensions are also known as role-playing dimensions because the single dimension can play multiple roles in the Analysis Services cube. Cube dimension is accessible inside that particular Cube, We can’t access the cube dimension in another cube. UseAsDefaultMeasure; In this article. It seems pretty well isolated, but occasionally (once a week, sometimes twice) it will fail with the following exception: I was giving it no specific instructions about what order it should process its individual Cubes and Dimensions. I can also create an MDX query as follows to return the last process time: I made it a dimension that is related to nothing. Returns a row for each measure, each cube dimension attribute, and each schema rowset column, exposed as a column. If the Dimension has a Dimension Structure that is editable, then I know that it is the source dimension. The reason being is that it creates a layer between the cube and the physical table. For example say I have a fact table that has an ID column which is unique, and an Age column that has customer ages in it. Improve this answer. SSAS 2012 - Dimension Modeling. It optimises the build time, storage and query performance. I then have some user roles in SSAS where I want to restrict the data a user will see in a measure group by a single RegionId i. SSAS Project: A dedicated project within SSAS for defining the cube’s structure. If I process the cube without processing the dimension, it's very likely the cube will generate date errors. Creating an OLAP cube allows for rapidly extracting data from multiple dimensions and tables. Analysis Services Processing Task. g. initiated this approach from 1 Dim, 1 partitions, related 1 cube. You should spend time in designing dimension and measure groups for optimal In the cube Dimension Usage, you can relate "MeasureGroup Dogs" to "Dimension Dogs" through a "Fact"-type relationship (the short description in the dialog helpfully says "The dimension table is the fact table"). Unless you are worried about tracking usage by SSAS model, I can't think of a good reason to duplicate the view for each tabular model. Then, deploy my cube in my server. 20 Right-click on the dimension or cube and select “Process”, and this should bring up a similar screen with processing options as shown in the below screenshot.
