Q) What are the types of user profiles and products can they use?
A) Supervisor offers standard profiles representing the
various types of Business Objects users. The names of the profiles, as well
as their symbols, roles, and products are explained below.
Profile) General Supervisor
Role) The Business Objects system
administrator. This is the person who launches Supervisor for the first
time. The general supervisor creates the repository, defines users and
groups, and manages resources. A general supervisor is the sole user with a
global view of the hierarchical organization.
Product) All Business Objects Products
Profile) Supervisor
Role) Defines users and group, manages
resources, and ensures security. A supervisor also assigns properties and
resources to these users and groups. In addition, a supervisor can restrict
access to certain resources. A general supervisor can create several
supervisors.
Product) Supervisor, BusinessObjects
Profile) Supervisor-designer
Role) Creates users, groups and universes.
This user has all the rights of the supervisor and designer combined.
Product) Supervisor, Designer, BusinessObjects
Profile) Designer
Role) Creates universes and distributes them
to end users by sending them through the file system, or by exporting them
to the repository.
Product) Designer, BusinessObjects
Profile) User
Role) The main BusinessObjects user whose
tasks are to query, report, and analyze data. Users can produce documents
containing data from one or more data sources. There can be an unlimited
number of users.
Product) BusinessObjects
Profile) Versatile
Role) This user is authorized to use any combination of
products defined by a supervisor.
Q) How do you Create a user group?
A) 1) In the User pane, click the group in which you want to create a new group.
2) Click on the toolbar.
3) Type a group name, and press the Enter key.
Q) How do you know if a user is Disabled?
A) A silly sad face.
Q) How do you enable a User?
A) Right click on the disabled user and select enable.
Q) How many strikes does it take before a user disables them?
A) 3
Q) What is a Category?
A) A keyword or phrase created by Supervisor and stored in
the repository, which end-users can assign to documents when they send them
to users, groups, or Broadcast Agent. Users can then filter document
searches in the repository by assigned category.
Designer Questions
Q) What is a Universe?
A) A universe is a business-oriented mapping of the data
structure found in databases: tables, columns, joins, etc. It can represent
any specific application, system, or group of users. For example, a universe
can relate to a department in a company such as marketing or accounting. In
the BusinessObjects User module, universes enable end users to build queries
from which they can generate and perform analysis. Universes isolate end
users from the complexities of the database structure as well as the
intricacies of SQL syntax.
Q) How many Universes did you create?
Q) Tell me how many classes where there, and objects in each class?
Q) What is an Object?
A) An object is the most refined component in a universe. It
maps to data or a derivation of data in the database. Using objects, end
users can build queries to generate reports.
Q) What is Object qualification?
A) For the purposes of multidimensional analysis, objects
are qualified as one of three types: dimension, detail, or measure.
Q) Tell me about a complicated object you have created?
Q) What was the size of the database? which server?
Q) What was the Database. Was it a data warehouse?
Q) What problems you have faced while creating an universe?
Q) Tell me an incident and how you went about solving it?
Q) How many Tables was the universe built?
Q) What is a loop, how do you resolve them?
A) A situation that occurs when more than one path exists from one table to
another in the universe.
Q) What do prefer an Alias or an context? why?
A) Alias - A logical pointer to an alternate table name. The
purpose of an alias is to resolve loops in the paths of joins.
A) Context - A context is a rule by which Designer can
decide which of two paths to choose when more than one path is possible from
one table to another. Contexts can be used to resolve loops in the universe.
You can create contexts manually, or cause them to be detected by Designer.
When contexts are useful, Designer suggests a list of contexts that you can
create.
Q) What is a join? Explain different types of joins?
A) A relational operation that causes two tables with a
common column to be combined into a single table. Designer supports
equi-joins, theta joins, outer joins, and shortcut joins.
Q) What are linked universes? Have you worked with them, problems faced and
solutions?
A) Linked universes are universes that share common
components such as parameters, classes, objects, or joins. Among linked
universes, one universe is said to be the kernel or master while the others
are the derived universes.
BusObj Questions
Q) How many reports have you created? Explain a few?
Q) What are alerter's, filters, breaks, conditions?
A) The Alerters dialog box allows you to create and apply
alerters. Alerters use special formatting to make data that fits specified
conditions stand out from the rest of the data. This helps draw attention to
trends and exceptions in report data.
A) A filter enables you to hide the data you do not want to
view and display only the data you want to focus on. In the Apply a Filter
on Variable Name dialog box, you choose which values of the selected
variable you want to display in the selected block.
A) Select the variables you want to use to insert a break.
When you close the dialog box, the variable you select is displayed in the
Breaks dialog box. Break Level, sets the level that the block of data will
have in the report. You can have more than one break level to organize
blocks of data.
A) conditions - feature that forces a query to retrieve only the data that
meets specified criteria.
Q) What's the difference between master-detail and Breaks?
Q) What's the difference between filters and conditions?
Q) What are pre-defined conditions? compare with report conditions? Justify?
Q) What are the differences between a formula, variable and user objects?
Q) Did you face any problems while creating reports? Name? Solutions?
Q) How do you schedule the reports?
Q) What is a micro cube? how many can a document have?
A) Local structure in which the data retrieved by a data
provider is stored; contains the data users can display in reports inside a
document.
Q) Have you worked with multiple data sources? If yes. How do you link them?
Q) What are templates? Explain what you have created?
Q) How do you resolve #multivalue and #computation errors?
Q) Difference between Foreach and ForAll?
A) Foreach - Adds a dimension to the calculation environment.
A) ForAll - Specifies the dimensions you want to include in the
calculation.
Q) Define a Cell, Block, Section?
