BO Designer Interview Questions and Answers

1 :: How do we design a universe?

The design method consists of two major phases.

During the first phase, you create the underlying database structure of your universe. This structure includes the tables and columns of a database and the joins by which they are linked. You may need to resolve loops which occur in the joins using aliases or contexts. You can conclude this phase by testing the integrity of the overall structure.

During the second phase, you can proceed to enhance the components of your universe. You can also prepare certain objects for multidimensional analysis. As with the first phase, you should test the integrity of your universe structure. You may also wish to perform tests on the universes you create from the BusinessObjects User module. Finally, you can distribute your universes to users by exporting them to the repository or via your file system.

For a universe based on a simple relational schema, Designer provides Quick Design, a wizard for creating a basic yet complete universe. You can use the resulting universe immediately, or you can modify the objects and create complex new ones. In this way, you can gradually refine the quality and structure of your universe

3 :: Explain in Detail abt Measure Objects? and what is the use of it? How to create it?

Measure objects are the objects which have facts i.e all $ amounts

a dimension object cannot be calculated with another dim object

in order to have a seperate identity for $ amounts we define as measure objects

just create an object for ex:revenue then right clicck on the object or double click on the object n then change the property of that object to measure its that simple

4 :: How to create Generic TIME CLASS, which includes Objects Year,Month and Qtr?
Database in use is Oracle?

If your database consist all dates something like 01/02/2000 or 01-Feb-2000, you will need to break the date field into year, qtr,month & if required date.

to do this, create a class named TIME, under that create new object, in it's select box use oracle's date functions to get required information.

For E.g. : to_char(sales_date, 'YYYY') for getting only year from the date.

similarly, for quarter you can use to_char(sales_date, 'Q')

& for month to_char(sales_date, 'MM') for month number, instead of 'MM' if you use 'MON' it will return you abrevations like Jan for January & so on. for full name of month use 'MONTH'

5 :: How to create Universe using Flat file in BO6.0?

Business Objects deals with databases, for every universe you need to specify a database connection. flat files dont have the database format so you'll need to convert them into some database. to do that, you will need to write a procedure which will read data from flat files & relate it according to surrogate keys, then using that procedure populate the database & then use that database for the source of the universe.

using flat files ONLY , you can not create universe. because there is nothing as database connection available for flat file.
