Define a Data Source View
Having defined the Data
Source within our Analysis Services Project, our next steps surround
the creation of the Data Source View, a procedure that is customary at
this stage in most Analysis Services Projects. It is important to
realize, as we work with a "live" data connection that we have
defined, that we could certainly continue our development efforts with the
metadata without an open connection. The Data Source View
provides a single, unified view of the metadata from the tables and views that
concern us within our project.
To define a Data
Source View, we will take the following steps:

Our newly created Data
Source is positioned as the default, and will serve us in meeting the objectives
of our practice exercise. It is particularly useful to note, however, that we
can define both a primary data source (a single Data Source like Adventure
Works DW is an example), and then add tables and views from secondary
Heterogeneous queries are supported as long as one Data Source is a MSSQL
Server Data Source.
We next arrive at the Select
Tables and Views
page, where we see the various tables of the Adventure Works DW data
source appear in the Available objects list box on the left of the page.
