What is level-based hierarchy in obiee 11g?
Hierarchies (Level-based hierarchy) in OBIEE 11G A hierarchy is a cascaded series of many-to-one relationships and consists of different levels. Example, a region hierarchy is defined with the levels Region, State, and City.
What is level-based hierarchy in obiee?
Level-based hierarchy is the first type of hierarchy in OBIEE. users from Dashboard and Answers to drill down from one parent to a child level. time dimension to provides special functionality for modeling time series data. When building a hierarchy in the Administration Tool, follow these rules. A hierarchy should only have one grand total level.
Is each leaf at the same level in obiee 11g?
So that, each leaf was at the same level. OBIEE 11g can handle this though with the new ragged and skip-level support for level-based hierarchies. It does this by detecting NULL s in either leaf levels (for ragged hierarchies) or other levels (for skip-level
How to tell obiee which dimensions are at detail level?
Every dimension should have a hierarchy with at least Total -> Detail levels. If your not talking aggregates at this point then the Dimensions LTS’s are more thank likely to be at detail level along with the fact. Once you set the Fact LTS level, you need to tell OBIEE which dimensions are also at that level.
Does obiee 11g support ragged and skip-level hierarchies?
If you were at the London launch of OBIEE 11g last week, or listened in on the webcast, you’ll have heard Paul Rodwick talk about support for ragged and skip-level hierarchies whilst he demonstrated the 11g version of the BI Administration tool.
What are the different types of hierarchies in BMM?
Hierarchies is a series of many-to-one relationships and can be of different levels. A Region hierarchy consists of: Region → Country → State → City → Street. Hierarchies follow top-down or bottom-up approach. Logical dimensions or dimension hierarchies are created in BMM layer. There are two types of dimensional hierarchies that are possible −
What are the different types of hierarchies in BMM layer?
- Dimensions with level-based hierarchies
- Dimension with Parent-Child hierarchies
What is hierarchy in DBMS?
A hierarchy is a many-to-one relationship between members of a table or between tables. A hierarchy basically consists of different levels, each corresponding to a dimension attribute.
What is a hierarchy in UDM?
A hierarchy defines the relative position of attribute members in a dimension. By default, in UDM, every attribute can form its own attribute hierarchy and dimensions are the containers for these hierarchies. Dimension may also contain user hierarchies which act as navigational paths to help the user in exploring the data from various angles.
What is the hierarchy of Management?
The hierarchy is a very resilient management structure that has been so embedded in how we work that most organizations around the world are having a tedious time getting rid of it. Today one thing is certain, the hierarchy belongs in a management museum locked up for people to see, but not touch.
What is a hierarchy in the workbench?
In other words, a hierarchy is a specification of levels that represents relationships between different attributes within a hierarchy. For example, one possible hierarchy in the date dimension is Year > Quarter > Month > Day. There are four major types of hierarchies that are supported by the workbench:
Is each leaf at the same level in obiee 11g?
So that, each leaf was at the same level. OBIEE 11g can handle this though with the new ragged and skip-level support for level-based hierarchies. It does this by detecting NULL s in either leaf levels (for ragged hierarchies) or other levels (for skip-level
What is level-based hierarchy in obiee 11g?
Hierarchies (Level-based hierarchy) in OBIEE 11G A hierarchy is a cascaded series of many-to-one relationships and consists of different levels. Example, a region hierarchy is defined with the levels Region, State, and City.
Does obiee expect each leaf member to be at the same level?
In 10g this would have been tricky, as OBIEE would have expected each leaf member to be at the same (not to be as in the above case, node C) level, and if they weren’t, you’d need to fudge the data a bit, for example by adding dummy child members to node C. So that, each leaf was at the same level.
How does obiee 11g handle Nulls?
OBIEE 11g can handle this though with the new ragged and skip-level support for level-based hierarchies. It does this by detecting NULL s in either leaf levels (for ragged hierarchies) or other levels (for skip-level hierarchies) and uses this to modify how the new hierarchical column type in Analysis handles the missing levels.
What is the difference between fact and dimensions LTS in obiee?
If your not talking aggregates at this point then the Dimensions LTS’s are more thank likely to be at detail level along with the fact. Once you set the Fact LTS level, you need to tell OBIEE which dimensions are also at that level. We set the content level of logical source based on the granularity of the source.
How does obiee 11g handle Nulls?
OBIEE 11g can handle this though with the new ragged and skip-level support for level-based hierarchies. It does this by detecting NULL s in either leaf levels (for ragged hierarchies) or other levels (for skip-level hierarchies) and uses this to modify how the new hierarchical column type in Analysis handles the missing levels.
To get these calculations to work right, I seem to have to use IfNull (metric,0) often, because apparently NULL plus a number equals NULL. #1 – If A and B are both NULL, the F column always shows as a 0 because the formula is IfNull (A,0) + IfNull (B,0). It would be nice if I could get F to also show NULL, without making the formula complicated.
