![SSAS 2017 TABULAR MODEL
New User Interface for getting the data.
When you get data, you now see a user interface similar to that used in PowerPivot and/or Power BI
Desktop.
Compatibilities Levels regarding the sql server analysis instance version to deploy.
Hide blank members from parent –child hierarchies.
IN,ConstrinatRows Functions in DAX.
IN keyword can be act as IN key word in SQL Server.
=if( [Amount] IN {20,30,40},”Sales Amount ”,”Tax Amount” )
Object Security : we can write the code in JSON or tabular model scripting language to secure the
tables ,columns .](https://image.slidesharecdn.com/ssastabularmodel-180409205656/85/SSAS-Tabular-model-importance-and-uses-11-320.jpg)

SSAS Tabular model importance and uses
- 1. SSAS TABULAR MODEL USING MICROSOFT SQL SERVER 2016 ANALYSIS SERVICES LAKSHMI PRASANNA.KOTTAGORLA APPLICATION DEVELOPMENT ANALYST
- 2. AGENDA: INTRODUCTION TO MICROSOFT SQL SERVER ANALYSIS SERVICES Types of Modes in SSAS. Introduction to SSAS Tabular Difference between SSAS Multidimentional and Tabular model Uses of Tabular Model. Tabular Model – sample Design About Calculate column and calculated measure Query Modes WHAT IS NEW IN SQL SERVER 2017 TABULAR MODEL
- 3. SQLSERVER ANALYSIS SERVICE(SSAS) • SQL Server Analysis Services (SSAS) is the technology from the Microsoft Business Intelligence stack, to develop Online Analytical Processing (OLAP) solutions. • In simple terms, you can use SSAS to create cubes using data from data marts / data warehouse for deeper and faster data analysis.
- 4. TYPES OF MODES IN SSAS BISM ( Business Intelligence schema Model) = Multidimenitonal (OLAP) Model + Tabular(Relational) Model.
- 5. SSAS TABULAR MODEL From SQL 2012 release Microsoft introduced Tabular data modeling along with the Multidimensional model. Tabular model is new type of data model that SSAS introduced. Tabular model is used for tabular/relational or Power pivot project. It’s only a little like “regular” Multidimensional SSAS…mostly different DirectQuery (Xvelocity) DAX Power Pivot,SSRS,EXCEl,Power Bi
- 6. DIFFERENCE BETWEEN SSAS TABULAR MODEL & SSAS MULTIDIMENSION MODEL. Tabular Model • Datasources: Relational databases, Analysis Services cubes, Reporting Services reports, Azure DataMarket datasets, data feed, Excel files and text files. • Development tools: SSDT,SSMS • Expression Language: DAX • Execution of query is fast and writing the quires are easy • Data volume is limited by availability of RAM. • Role playing dimensions are partially supported. Multidomensionla model • Datasources: Relational Databases • Development tools: SSDT,SSMS • Expression Language: MAX • Execution of query takes time when huge data present. • The quires which are written complex in nature. • Uses the Ram as well disk space • Role playing dimensions are supported.
- 7. WHERE THE TABULAR MODEL IS USED? POWER VIEW (IN EXCEL) POWER BI SQLSERVER REPORTING SERVICES(SSRS)
- 8. BUILD THE TABULAR MODEL Source : AdventureWorks SQL Server Management Studio SQLServer Analysis Services Plan Creating the project Add data source Add measure & calculated columns Add the KPI’s Add partitions & Roles Add Perspectives. Modes Process etc.
- 9. CALCULATE COLUMN & CALCULATE MEASURE • Calculated Columns • Use when operating on data in a single row • Won’t change regardless of slicing done in client tool • Calculated Fields (Measures) • Math (aggregations) done across multiple rows • Calculated as-needed based on slicing of data
- 10. QUERY MODES Tabular model implemented either in-memory or direct query mode. In-memory mode: The Tabular model can be deployed with in –memory mode: Here the quires which are requested by the client can directly hit the SSAS tabular model from the Analysis services. Once process the model the data can be imported into in-memory. With help of this mode we can get the data very fast . Direct Query: Ones request received from the client tool the queries are directly hit the underline source either sql server or oracle which connected to build the tabular model. The Tabular model can hold the structure of the model in the tabular model database. This Mode is suitable at time of large volume of the data than availability of memory size
