Adding Multiple Sources Data is often partitioned into multiple physical sources for a single logical table in a business model. When a logical table source does not contain the entire set of data at a given level, you need to specify the portion of the set that it does contain. When individual sources at a given level contain information for a portion or fragment of the domain, Oracle BI Server needs to know the content of the sources in order to pick the appropriate source for the query. The goal is to provide seamless and efficient access from the users' perspective. When there are multiple sources, the metadata is built so that Oracle BI Server handles the navigation to the appropriate source. Oracle BI Server can seamlessly access and process data from multiple sources in an efficient manner to satisfy users’ requests. In this example, sales quota numbers are stored in an Excel workbook. The workbook, SHQuota.xls, is stored on your machine. You incorporate the quota numbers into the business model and create business measures to report variance from quota and percent of quota. To add quota information to the business model, you perform the following steps. Create an ODBC DSN Import the Excel Source Map Logical Dimension Columns Create Quota Measures Test To create an ODBC DSN for the Excel workbook, perform the following steps: 1. Using Windows Explorer, navigate to the SetupFiles folder and copy the SHQuota.xls file to a location on your machine. 2.

In this example, sales quota numbers are stored in an Excel workbook. The workbook,
SHQuota.xls, is stored on your machine. You incorporate the quota numbers into the
business model and create business measures to report variance from quota and percent
of quota.
To add quota information to the business model, you perform the following steps.
Create an ODBC DSN
Import the Excel Source
Map Logical Dimension Columns

To create an ODBC DSN for the Excel workbook, perform the following steps:
1. Using Windows Explorer, navigate to the SetupFiles folder and copy the SHQuota.xls file to a
location on your machine.
2. Click Start > Programs > Administrative Tools > Data Sources (ODBC) to open the ODBCData Source Administrator.
two logical table sources: CUSTOMERS and COUNTRIES.
2. Drag the physical column COUNTRY_REGION from Geography in the Physical layer to the
logical column Customers.Country Region in the Business Model and Mapping layer. Noticethat a new logical table source, Geography, is created automatically.
3. Drag the physical columns COUNTRY_SUBREGION, COUNTRY_NAME, COUNTRY_ID,
and COUNTRY_TOTAL from Geography in the Physical layer to the corresponding logical
columns in the Customers table in Business Model and Mapping layer (DragCOUNTRY_NAME to Country).
4. Double-click the Geography logical table source in the Customers > Sources folder to open theLogical Table Source dialog box.
5. Click the Column Mapping tab. Notice the logical to physical column mappings.
8. Drag the remaining physical columns from XLDates in the Physical layer to the corresponding
logical columns in the Times table in Business Model and Mapping layer.
9. Double-click the XLDates logical table source in the Times > Sources folder to open the LogicalTable Source dialog box, click the Column Mapping tab, and verify the mappings. Note that
"Show unmapped columns" is unchecked.
10.Click OK to close the Logical Table Source dialog box.
11.Repeat the steps and map Products.Prod Category to ProdCategory.PROD_CATEGORY and
