Free Access Oracle 1z0-591 New Release

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).

You have three sort of fragmentation:

Fact-based / Dimension-based fragmentation

Content-based / Value-based fragmentation

Level-based fragmentation / aggregate navigation

You can combine the techniques above to construct powerful design that are known as Complex partitioning / fragmentation. When you fragment a dimension, you are automatically in a complex fragmentation.

CurrentDay and CurrentMonth can be calculated by a sql statement.

Note:
