BO Interview Questions Answers Explanations

BO Interview Questions with Answers with Explanations.

What is the difference between linking and including the universes?
Answer : 

• Linking a universe is a process, which includes the required objects/classes of the master on to the derived universe. But any change made to the master universe is reflected onto the derived universe.
• Including a universe creates all the required objects from the master universe on to the derived universe; any change made to the master universe does not impact the derived universe.

What is Supervisor?
Answer : 

• Supervisor is the product for the secured deployment of Business Objects products. It provides a powerful and easy-to-use solution for user administration.
• Using this product, you can define users and user groups. You can also ensure the secured access of these users and groups to the various Business Objects resources such as universes and documents.
• Supervisor can run only in client/server mode. Its use requires a connection to a relational database. Any operation you perform with Supervisor is written to the repository.

What are the User Profiles offered by Supervisor?
Answer : 

• General Supervisor (Can access all products of Business Objects)
• Supervisor (Can access all products except Designer)
• Designer (all products but SUPERVISOR)
• Supervisor-Designer (all products)
• User (all products but DESIGNER and SUPERVISOR)
• Versatile (configurable)

What are the functions of Supervisor User Profiles? 
Answer : General Supervisor (GS): is the senior system administrator. Using SUPERVISOR, the GS can:

• Create repositories (When a Repository is created automatically a General Supervisor is created)
• Create any type of user, including other general supervisors
• Create user groups
• Administer user accounts and privileges for repository users
• Import and export universes to and from the repository
• Define a BROADCAST AGENT for a group
• Launch a BROADCAST AGENT from the BROADCAST AGENT Administrator

Supervisor: is responsible for user administration.

• Create users with any profile except General Supervisor
• Create user groups
• Administer user accounts and privileges for repository users
• Import and export universes to and from the repository

What is a Repository? 

Answer : A Business Objects repository is a centralized set of relational data structures stored in a database. It enables Business Objects users to share resources in a controlled & secured environment.

Repository comprises three types of domains:

• Security domain: which contain the definition of the other domains as well as the definition of users
• Universe domains: It holds the exported universes. It makes it possible to store, distribute and administrate universes. There may be multiple universes in a repository.
• Document domains: is a set of data structures in the Business Objects repository that contains information on stored documents, lists of values, scripts or stored procedures.

Repository holds 50 objects or tables:

• Security Domain: 23 + 2 (For BCA), Universe Domain: 24 tables, Document Domain: 1 table
• Security Domain: Tables start with OBJ. Ex: obj_m_actor, obj_m_repository, obj_m_universes, obj_m_documents etc.
• BCA Tables: 1. DS_Pending_job 2. DS_User_List
• Document Domain: Obj_X_Documents
• Universe domain: Tables start with UNV. Ex: unv_join, unv_table, unv_universe

How to Choose a Repository Database?

Answer : Administrators who have the opportunity to choose a database platform for their repository are advised to consider the following issues:

• Databases which support row-level locking to avoid locking conflict.
• Databases which support BLOBs (Binary Large Object) for document storage. BLOB format improves Repository performance & network traffic.
