![]() Microsoft have been steadily closing the gap between Power BI and Analysis services. Now right click on project ,click Open Folder in Windows Explorer and close SSDT. It is read-only and that’s the one we want to change. As you would notice, Workspace Database cannot be changed. This course is suitable for delegates working with SQL Server 2012 through to SQL Server 2016. Power BI A method to Uplift a Power BI Report to a SSAS Tabular model. If you open SSMS and connect to SSAS Tabular instance, you should find a database with the same name as this property value. This course also covers the interrogation of Tabular Models from Microsoft Excel 2010/2013 through Pivot Tables and Charts, and the use of Tabular Models as data sources for SQL Server Reporting Services (SSRS). An introduction to the DAX language will provide an insight into extending data models by adding simple aggregate type measures and calculations to the model through to complex Time-Intelligence based measures, such as parallel period calculations, year to date, month to date, etc. The main emphasis of the course is on the design and creation of Tabular Models, but basic administration and security of models are also covered. The course will take delegates through building a Tabular Model in its simplest form through to extending the features within the model by implementing DAX calculations and measures, and Key Performance Indicators (KPIs). Delegates will be introduced to the concepts of Transactional Relational Databases, Data Warehouse Relational Databases, other sources of data, and Tabular (PowerPivot) Models fundamentals, becoming familiar with terminology such as Tables, Data Sources, Relationships, Hierarchies, Calculations & Measures. In this chapter, we will cover the following recipes: Getting started with Power BI desktop Adding data to Power BI reports Using the SSAS tabular model as. You will learn about the Microsoft SQL Server Visual Studio development environment (SQL Server 2012/2014 Data Tools) for design, creation and deployment of SQL Server BISM (Business Intelligence Semantic Model) Tabular Mode projects, and SQL Server Management Studio for the management of Tabular Models. (In my case, I used Windows Authentication. When the Data Connection Wizard appears, type the instance name and any necessary logon credentials, as shown in Figure 5. a Date dimension.In this course, you will learn how to use Microsoft SQL Server Analysis Services (SSAS) to design and implement Tabular PowerPivot Models to support Business Intelligence (BI) solutions. To connect to a tabular database from within Excel, go to the Data tab, click the From Other Sources button, and then click From Analysis Services. Double click on the DimDate table name to rename it to a user friendly name. This works like a charm, especially when analyzing over a dimension with many values, i. Importing DimDate into your tabular model several times: In our sample we need to import it three times to cover Order Date, Ship Date and Due Date. of Customers (Optimized) = SUM(’HelpTable_DistinctCount') All you have to do now is to create a relationship over the ID columns with a both way cross filter direction so that the fact table filters your new help table.Īnd of course, change your existing measure to this: No. This way I can now do a SUM() of values in my new column instead of counting values, and with the same result but with a much faster query. Then I’m adding a column containing 1 for each ID. And instead of writing a DAX measure that can take you to the moon, this problem can be solved with some small architectural changes in the model.įirst, I’m creating a new help table, consisting of two columns, the key is a distinct of IDs that I initially wanted to do a count of. Online SSAS - Tabular Model course This page has 0 threads Outstanding course feedback Average score 9. of Customers = DISTINCTCOUNT(’Fact')īut as rows keep appearing in the model, you might experience a decrease in performance since the query engine now needs to go through more rows and sort more values. ![]() Normally this is how you typically write a DistinctCount() measure: There are as many ways of writing a DAX measure as there are BI developers out there, but here is my way of maintaining high performance when counting distinct values in a (100M+) tabular model.
