7. Tabular model architecture

8. Tabular mode  In-memory – по умолчанию режим работы. Движок Vertipaq  DirectQuery – метаданные разворачиваются без данных  In-memory with DirectQuery – в этом режиме необходимо обработать кэш, прежде чем получить доступ к данным  DirectQuery with In-memory - кэш разворачивается и доступен клиенту

9. How does it work?

10. SQL Server Analysis Services 2016

13. Relationship. Many-to-many? Realy? In practical terms, cross-filtering can enable forms of data exploration typically delivered only through a many-to-many construction. Having said that, it’s important to recognize that bi-directional cross-filtering is not a many-to-many construct. An actual many- to-many table configuration remains unsupported in the designer for tabular models in this release. Bi-directional cross filters

14. DBCC for SSAS For Tabular databases, consistency checks performed by DBCC are equivalent to the built-in validation that occurs automatically every time you reload, synchronize, or restore a database. In contrast, consistency checks for Multidimensional databases happen only when you run DBCC on demand.

15. Translation and Display folder

16. Perfomance  Parallel processing for multiple table partitions  DirectQuery now generates simpler queries that provide better performance  Improved SSDT modeling performance for Tabular 1200 models  Performance optimization: redundant join elimination for VertiPaq and DirectQuery  Update AMO

17. DAX: variables  We can define VARIABLES in DAX Syntax: VAR = TermDefinition nameThe name of the variable (identifier). Empty spaces are not allowed. expressionA DAX expression which returns a scalar or table value.

18. DAX: calculate tables A calculated table is a computed object, based on either a DAX query or expression, derived from all or part of other tables in the same model. Role-playing dimension

19. DAX: new function Over 50 new function Date and Time function Other function Filter Functions Text Functions Math and Trig functions Statistical Functions New function in MSDN

20. DirectQuery Excel and other MDX clients in DirectQuery mode Import and processing in DirectQuery mode Security in DirectQuery Mode Calculated tables – no, no, no. Calculated columns
