Who am I? Gabi Münster BI consultant at oh22data AG since 2010 Experience with SQL Server since version 2000 Main topics: SSAS (Multidimensional/Tabular), SSRS, MDS, PowerBI Speaker at chapter meetings and national and international conferences

Agenda Multi-client SSAS deployment Motivation A little bit of theory How can a config look like? How to deploy a multidimensional database with AMO? How to deploy a Tabular model with TOM? Resumé

Motivation Enhancement of testing possibilites Enabling of staff Realization of multi-szenario deployments Version control Added value for documentation

A little bit of theory (I) Understand the SSAS data model Very flexible Lots of objects Large variety of attributes Deeply interlaced Very complex

A little bit of theory (II) <Server> <Name/> <ID/> <Description/> <Version/> <Edition/> <Databases> <Database> <CreatedTimestamp/> <LastSchemaUpdate/> … <Dimensions> <Dimension> <Source> <!-- Binding --> </Source> <DimensionPermissions> <DimensionPermission xsi:type="Permission"> ... </Dimension> </Dimensions> <Cubes> <Cube> </Databases> <Roles> <Role> </Role> </Roles> </Server> A little bit of theory (II) 2. Choose the language: ASSL => XML based AMO => .NET class library Server srv = ServerConnect(strConn); Database db = CreateDatabase(srv, strDBName, true); if (db == null) { return "Failure"; } DataSource ds = CreateDataSource(db, "AdventureWorksDW2014", "Provider=SQLNCLI11.1;Data Source=.\\SQL2016;Integrated Security=SSPI;Initial Catalog=AdventureWorksDW2014"); if (ds == null)

A little bit of theory (III) Understand the data model Meant for comprehensibility Less objects Less interdependencies Easier to understand and maintain

A little bit of theory (IV) 2. Choose the language: TMSL => JSON based TOM => .NET class library // Generate a new database name and use GetNewName // to ensure the database name is unique. // string newDatabaseName = server.Databases.GetNewName(strDatabaseName); string newDatabaseID = server.Databases.GetNewID(strDatabaseID); // Instantiate a new // Microsoft.AnalysisServices.Tabular.Database object. var dbWithTable = new Microsoft.AnalysisServices.Tabular.Database() { Name = newDatabaseName, ID = newDatabaseID, CompatibilityLevel = 1200, StorageEngineUsed = StorageEngineUsed.TabularMetadata, };

How can a config look like? What of the data models are you using? What is „static“, what needs configuration? Build step by step Demo

How to deploy a multidimensional database with AMO? Example: .Net Choose integration: Stand-alone application Assembly to use in SSIS … Demo

How to deploy a Tabular model with AMO? Example: .Net Choose integration: Stand-alone application Assembly to use in SSIS … Demo

Resumé Cost/benefit evaluation necessary Criteria Assessment Funktionality Covers all necessary functionality Implementation effort High! Potential benefit Also high Cost/benefit evaluation necessary Especially meaningful for consulting companies with different customers (reusability)
