If you have no particular leaning on any of these questions then you have a little more to think about, or maybe not. Tabular Modelling is easier than Multi-Dimensional modellingĪlthough Power BI can consume data from both Multi-Dimensional Cubes and Tabular Models, it integrates seemlessly with Tabular Models hosted in Azure Analysis services. Only Multidimensional Cubes support writeback. Only Multidimensional Cubes offer automatic support for Ragged Depth Hierarchies and Custom Rollups Only Tabular Modelling allows for ETL work to be carried out in the model Only Multidimensional cubes allow Actions to be built into the cube to support hyperlinks. Only Tabular Models allow additional fields for dimensions (referred to as tables in Tabular models). Only Tabular Models are supported in Azure Analysis Services ![]() If you answered YES to any of the above then your decision may be straight forward: In many instances you could choose either, but 8 key questions to ask before making your decision are:Īre you planning on deploying to Azure Analysis Services or On-Premise Analysis Services?ĭo you wish to be able to extend your analytics model with custom dimension fields/expressions?ĭo you wish to embed hyperlinks into your analytics model?ĭo you wish to carry out ETL operations within your analytics model or using a service such as SSIS prior to building your analytics model?ĭo you wish to have automatic support for Ragged Depth Hierarchies and Custom Rollups?ĭo you require writeback capability to your analytics model?ĭo you have any Multidimensional or Tabular design experience with your business?Īre you planning on using Power BI to deliver enterprise wide reports and dashboards? If you have Microsoft SQL Server and a need for an Analytics solution you have a dilemma: Multidimensional Cube or Tabular Model? ![]()
