Search This Blog Kashinathan on Google+ Search Example, a region hierarchy is defined with the levels Region, State, and City. In the Business Model and Mapping layer, a dimension object represents Follow @Kashinathank a hierarchical organization of logical columns (attributes). One or more logical dimension tables can be associated with at most one dimension object. Common dimensions might be time periods, products, markets, Live Traffic customers, suppliers, promotion conditions, raw materials, manufacturing plants, transportation methods, media types, and time of day. Note that dimensions exist in the Business Model and Mapping (logical) layer and in the Presentation layer. There are two types of logical dimensions: 1. Dimensions with levelbased hierarchies (structure hierarchies). 2. Dimensions with parentchild hierarchies (value hierarchies). Levelbased hierarchies are those in which members are of several types, and members of the same type occur only at a single level. In parentchild hierarchies, members all have the same type. Oracle Business Intelligence also supports a special type of levelbased dimension, called a time dimension, that provides special functionality for modeling time series data.

For example, a Time hierarchy might have three levels for Year, Quarter, and Month. Level based hierarchies can also contain parentchild relationships. The recommended sequence for creating logical levels is to create a Grand Total level and then create child levels, working down to the lowest level. ► October (67) Levelbased Dimension hierarchy levels allow: to perform aggregate navigation, to configure levelbased measure calculations, http://dwhlaureate.blogspot.in/2012/08/dimensionhierarchiesinobiee_2.html ► September (90) ▼ August (107) Latest Transformations In Informatica Extracting and Loading Mechanism in DAC DAC Process Cycle 1/6 Skiplevel hierarchy : A skiplevel hierarchy is a hierarchy where there are members that do not have a value for certain higher levels.IBM Cognos BI Tool Components" 4 A visitor from Bangalore. ago Andhra Pradesh viewed "Cognos Components. the previous month's data at the month level.
