Agenda SSAS 2016 Features What will come with vNext? And how about Azure Analysis Services?

BI Semantic Model 2016

SSAS 2016 Features Modeling (I) Improved modeling performance for tabular 1200 models Up to three times faster Project templates added for tabular 1200 models in SSDT Only one SSDT for database and BI Display folders New to tabular level 1200 Bi-directional cross filtering Very important improvement that enables you to design many-to-many relationsships But be wary you check your results for plausibility and consider performance loss

SSAS 2016 Features Modeling (II) Translations Pasted tables Now available in Tabular as well Pasted tables Upgrade from level 1100 and 1103 models containing pasted tables now possible Calculated tables in SSDT Important feature for more complex requirements like pre-aggregations etc. Formula fixup Renamings will be published throughout the model Support for Visual Studio configuration manager Configuration for multiple environments

SSAS 2016 Features Instance Management Administer Tabular 1200 models in SSMS In the latest version of SSMS And host tabular models of any compatibility level in one instance Parallel processing for multiple table partitions in tabular models Add computer accounts as Administrators in SSMS DBCC for Analysis Services Extended Events updates

SSAS 2016 Features Scripting Tabular Model Scripting Language (TMSL) supported in SSMS

SSAS 2016 Features Scripting PowerShell for Tabular models SSMS scripting database operations Analysis Services Execute DDL Task SSAS PowerShell cmdlet Tabular Model Scripting Language (TMSL) supported in SSMS

SSAS 2016 Features DAX Improved DAX formula editing DAX variables New DAX functions https://msdn.microsoft.com/library/mt704075.aspx Save incomplete measures

SSAS 2016 Features DAX Non empty calculation - Reduces the number of scans needed for non empty. Measure Fusion - Multiple measures from the same table will be combined into a single storage engine - query. Grouping sets - When a query asks for measures at multiple granularities (Total/Year/Month), a single - query is sent at the lowest level and the rest of the granularities are derived from the lowest level. Redundant join elimination - A single query to the storage engine returns both the dimension columns and the measure values. Strict evaluation of IF/SWITCH - A branch whose condition is false will no longer result in storage engine queries. Previously, branches were eagerly evaluated but results discarded later on.

SSAS 2016 Features DirectQuery New DirectQuery implementation DirectQuery now generates simpler queries that provide better performance. Extra control over defining sample datasets used for model design and testing. Row level security (RLS) is now supported for tabular 1200 models in DirectQuery mode. Previously, the presence of RLS prevented deploying a tabular model in DirectQuery mode. Calculated columns are now supported for tabular 1200 models in DirectQuery mode. Previously, the presence of calculated columns prevented deploying a tabular model in DirectQuery mode. Performance optimizations include redundant join elimination for VertiPaq and DirectQuery. New data sources for DirectQuery mode Oracle, Teradata, Microsoft Analytics Platform

Features by edition – Analysis Services

Features by edition – BI semantic model Multidimensional 1 The LastChild semi-additive measure is supported in Standard edition, but other semi-additive measures, such as None, FirstChild, FirstNonEmpty, LastNonEmpty, AverageOfChildren, and ByAccount, are not. Additive measures, such as Sum, Count, Min, Max, and non-additive measures (DistinctCount) are supported on all editions. 2 Standard edition supports linking measures and dimensions within the same database, but not from other databases or instances.

Features by edition – BI semantic model Tabular

What‘s new with vNext? 1400 Compatibility level for tabular models Modern Get Data experience in SSDT Ragged hierarchies Hide Members property with option Hide blank members Detail Rows Detail Rows Expression property for measures Default Detail Rows Expression property for tables DETAILROWS DAX Function

What‘s new with vNext? DAX enhancements Table-level security IN operator Table-level security Encoding hints https://blogs.msdn.microsoft.com/analysisservices/2017/02/17/encoding-hints-and-sql-server-analysis-services-vnext-ctp-1-3

And what about Azure Analysis Services? Full functionality of Analysis Services Tabular for level 1200 models Dynamic scaling options Scale up/down, Start/Stop/Pause Cloud and On-Premises Data Sources (using Data Gateway) Access data from anywhere (Cloud, On-Premise) Same toolset (SSDT, SSMS)
