some concepts in BO

[former_member186160]

hi all,

pls help me in understanding these below concepts of BO.

i have also listed my understanding in italics.

pls correct me or add anyting relevant

1. universe import Vs export

export: making universe structure availble to repository inturn which can be using by various reporting tools in BO.

2. difference between types of objects   dimension/detail/measure objects

measure objects: like kfg , to quantif

dimension objects : place holder for objects , like dimension in infocube

detail objects : this confused me

3. kernel universe Vs master universe

Hi Swetha,

1. universe import Vs export: Universe export means exporting the structure to repository and import means importing the universe from repository or local business objects folder.

2. difference between types of objects   dimension/detail/measure objects:

Dimension object: A dimension maps to one or more columns or functions in the database that are key to a query. Dimension is the default qualification t object creation.

Ex- Resort, Country, employee.

Detail Objects: Detail provides descriptive data about a dimension. A detail is always attached to a dimension. It maps to one or more columns or functions in the database that provide detailed information related to a dimension.

      Ex- Age, Phone number, address

Measure Object:

• Measure -Contains aggregate functions that map to statistics in the database.  Measures are very flexible objects as they are dynamic. The returned values for a measure object vary depending on the dimension and detail objects used with it in the query. It always return numeric information.

        Ex- Revenue, number of guests, margin

3. kernel universe Vs master universe:

Kernel approach
With the kernel approach, one universe contains the core components. These are the components common in all universes. The derived universes that you create from this kernel universe contain these core components as well as their own specific components.
 
Any changes you make to the kernel universe are automatically reflected in the core components of all the derived universes.
 
 
Master approach
The master approach is another way of organizing the common components of linked universes. The master universe holds all possible components. In the universes derived from the master, certain components are hidden depending on their relevance to the target users of the derived universe.
The components visible in the derived universes are always a subset of the master universe. There are no new components added specific to the derived universe.
 
Any changes you make to the master universe are automatically reflected in the core components of all the derived universes.

Hope this info helps...
