An organization has re-implemented one of its systems but has not moved history. One database has data for all years up to 2010 and the other has data for years from 2011 to the present. The organization needs data from the years 2010 and 2011 on a single report. How can you model this in the RPD?
A. By creating two Logical Fact Tables for each database
B. By creating joins in the physical model so it looks like a single table
C. By creating two logical table sources, that specify in Content tab using the Fragmentation content areas to specify the years for each source
D. By creating two logical table sources and checking the "This Source should be combined with other sources at this level" box leaving the Fragmentation content area blank.
E. By creating one logical table sources and checking the "This Source should be combined with other sources at this level" box
Correct Answer: C
Explanation/Reference:
Note: This source should be combined with other sources at this level (check box)
Description: Check this box when data sources at the same level of aggregation do not contain overlapping information. In this situation, all sources must be combined to get a complete picture of information at this level of aggregation.
Note 2: To use a source correctly, the Analytics Server has to know what each source contains in terms of the business model. Therefore, you need to define aggregation content for each logical table source of a fact table. The aggregation content rule defines at what level of granularity the data is stored in this fact table.
Use the Content tab of the Logical Table Source dialog box to define any aggregate table content definitions, fragmented table definitions for the source, and Where clauses (if you want to limit the number of rows returned).
