![]() The extensive possibilities are both a curse and a blessing. Object size, placement, fonts, and colors can be set as desired. MS Power BI provides a wide variety of formatting options. ![]() ![]() It is founded on the selection and structure prevailing in Microsoft’s visualization menus. Compared to Tableau, this approach in Power BI is not as free and flexible. This is done via a selection of predefined visualizations, which can then be filled with the corresponding dimensions and key figures. Instead, individual visualizations are placed directly on a worksheet and then assembled to create a dashboard Visualizations are not first created in different worksheets and then integrated into dashboards. Power BI takes a different approach for creating dashboards and reports in comparison to Tableau. Power BI Vs Tableau - Visualization (Reports & Dashboards) This relational structure makes working with Tableau much easier. This often results in requirements for the underlying data sources, which should have a relational structure if possible. The data merging is helpful if the data sources used to contain data that have a different level of detail or granularity.Ī flat table is generated from all the links in Tableau, which then forms the basis for data visualization and analysis. Also, Tableau offers the function of data blending. Also, links between tables in the same database and between tables in different databases are supported by Tableau. In addition to the overall data union or linkage, you can also link together data sources together in Tableau. Tableau users can also connect to data sources in many different ways. Power BI can map relational structures and allows cross filters between tables. Classic data analysis structures can be taken directly from the data warehouse and enriched with additional tables such as a date or region table. The creation of ER models with different cardinalities is also very much possible with Power BI. The well-known Microsoft menu structure and visual aids enable creating complex data models directly in Power BI, without requiring any in-depth programming knowledge. Also, the data tables can be linked and edited directly into the user interface of Power BI. If we consider Power BI, then data can be converted and modeled by using the Power Query “Formula Language M” or thorough user interface options. Nevertheless, once data sources are connected with Tableau or MS Power BI, you can identify the clear difference in terms of data linking and data modeling. Because both Tableau and MS Power BI have an assorted range of connectors that enable users to easily connect the most common databases and flat files. Therefore, you cannot decide over a single winner when it comes to the data connection. All common data sources such as files (Excel, CSV), databases (SQL, Oracle), or online services (Salesforce, Google Analytics) are supported. Power BI Vs Tableau - Data Connection & Preparationīoth Power BI and Tableau have many options for connecting data sources. To give a first insight into the differences and strengths of the two tools, we have selected and compared some relevant functions. Each company will still have to decide independently which tool offers them the right set of features and functionalities considering their requirements and respective areas of application. Power BI and Tableau are leaders in the self-service BI market. So much is anticipated, there is no general answer to this question. The client usually asks this question when they want to compare the two and want to two that solutions are more suitable for self-service BI, especially when you have specific requirements. One of the primary questions that always come to our table during customer projects is that how similar or different are MS Power BI and Tableau from each other.
