Items that appear in Power BI Desktop depend on your permissions for the tabular model you’re connected to. Keep in mind that tabular models are highly secure. You’re always looking at the latest data that is available in the tabular model, either from the last processing time, or from DirectQuery tables available in the tabular model. Each time you interact with a visualization, Power BI Desktop queries the tabular model and calculates the results you see. When connecting live, no data from the tabular model is imported into Power BI Desktop. You can use Power BI Desktop’s advanced visualization and report tools to explore your tabular model in new, highly interactive ways. Indexing which includes covering indexes is done by default with the ability to override on a per table basis.With Power BI Desktop, there are two ways you can connect to and get data from your SQL Server Analysis Services tabular models: Explore by using a live connection or select items and import them into Power BI Desktop.Įxplore by using a live connection: When using a live connection, items in your tabular model or perspective, like tables, columns, and measures appear in your Power BI Desktop Fields pane list. hashed, binary values for better performance. A few simple table classifications help to optimize the code that is generated and includes i.e. TX2012 is also build to scale and perform, thus it includes support for a wide range of loading strategies such as source- and target based incremental load, just as table partitioning and data compression is a five minute operation to implement. Although the Meta data driven engine in tX2012 is powerful enough to also support other models such as Inmon and Data Vault, tX2012 has an emphasis on the star schema model, also known as Kimball dimensional modeling which means that features such as surrogate keys, slowly changing dimensions, aggregations and almost everything else from the 34 subsystems of ETL are supported. The star schema model is the most widely used data model for data warehousing, and the de facto standard for business focused reporting. Data warehouses can be modeled in a relational or dimensional form of which the latter is the most common. Data is collected over time and stores historical events that are often not persisted in the source systems and is also commonly referred to as the single version of the truth, making the data warehouse an important asset for the organization. The overall purpose of a data warehouse is to integrate corporate data from various internal- and external data sources.
