sql server connection string server vs data source

The requirement to frequently change those passwords also pinpoints where the password needs to be changed: at the service. This enables a better and more secure system. System Administers in IT today prefer services run from an Active Directory account.

This relieves the option of having to use a name and password or using the current user permissions for processing. The service account running the Analysis Service’s service will need to have access to the source data. The best practice for Impersonation Information is selecting Use the service account. But, there are times where shared dimensions are in different databases like a Master Data Management System.Īfter selecting the Instance and database to connect, the Impersonation Information appears like in Figure 4. Well-designed dimensional models will have all fact and dimension tables within one database. This is from where the data mart or data warehouse gets selected. To add a connection to the project, right-click the Data Sources folder in the solution explorer and select New Data Source… The Data Source Wizard will step through the needed selections for the connection. The Tabular Model does have a relationship view, but you cannot separate different views of the relationships like a Data Source View in a cube.įigure 2 shows Visual Studio creating a Multidimensional Cube project while Figure 3 shows the solution explorer of this new project.įigure 2 – Creating a Multidimensional Cube Project Multidimensional also allows multiple cubes in one project, whereas Tabular has only one model – for now. The cube can layout the relationships a little better with Data Source Views. The connection properties are very similar, but the retrieval of the data through tables or table-like sources is a little different.

The first step with a Cube or Tabular Model is to pick a connection or connections to data sources. Data Source connections are the first step to review with both versions.įigure 1 shows the option during installation to pick the type of Analysis Service. But, with the developer’s edition, both can be installed and reviewed before a production decision is made.

That could mean additional license costs. Both types can be installed on the same server, but they must be different instances. For someone new to SQL Server Analysis Services, a decision must be made on whether to use a Multidimensional Cube or Tabular Model.
