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)
1.
Understand the SSAS data model
1.
Very flexible
2.
Lots of objects
3.
Large variety of attributes
4.
Deeply interlaced
 Very complex
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)
{
return "Failure";
}

A little bit of theory (III)
Understand the data model
1.
1.
Meant for comprehensibility
2.
Less objects
3.
Less interdependencies
4.
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?
1.
2.
3.
What of the data models are you using?
What is „static“, what needs configuration?

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)
