Web Intelligence Interview Question Part 1

What is Web Intelligence?

With Web Intelligence, we can access the data in the corporate databases or data

warehouses from within the office, home or around the world using corporate intranet,

extranet or World Wide web.

No Webi software needed to be loaded on your computer.

You can save these documents on your local drive or send them to other users or publish

them to the corporate repository for potentially even broader circulation

What is WEBINTELLIGENCE System's Architecture?

1. The client: The Web browser, which provides the gateway to the Webi system.

2. The middle tier: Comprises the HTTP server and Webi system components, linked

together by CORBA calls in a distributed CORBA environment.

3. The Server: Comprises the repository and corporate database. This is where much of

the data is stored, and where system security is controlled.

Middle Tier:

HTTP Server: Web Intelligence’s HTTP server interface is the user's main gateway to

the WEBINTELLIGENCE system. It is the main channel for receiving and servicing

client requests. The HTP server includes the HTTP Server Abstraction Layer (HSAL).

The HSAL receives user requests for WEBINTELLIGENCE services and converts them

from the gateway protocol and from that WEBINTELLIGENCE understands.

WIDispatcher: is the system's URL router. Whenever the WIDispatcher receives a

translated request from the HSAL, it decides which process the request should be sent to,

then convert the textual URLs into CORBA requests that can start the required

WEBINTELLIGENCE process.

WISession Manager: performs user validation, and tracks all activity from the time

users log in until they logout. It also keeps track of all the enabled WIGenerators in the

cluster. At login time, it can assess which WIGenerator has the lightest transaction load,

and assigns the new user's WIQT process to it.

WIGenerator: The WIGenerator module is used to generate the framework for the

HTML pages (such as document lists and user start pages), excluding the actual

document content. The documents themselves are generated by the

WEBINTELLIGENCE Query Technique (WIQT) processes. The WIQT processes can

be distributed within a cluster (load balancing).

BOManager : This component launches and manages a “pool” of BUSINESSOBJECTS

processes via OLE Automation under Windows (local calls only), and CORBA under

UNIX. It also manages multitasking and maintains user context.

WIStorage-Manager: manages the WEBINTELLIGENCE system’s cache and

document storage areas.

Scheduler: The BROADCAST AGENT Scheduler periodically polls the repository to

detect tasks to run. It then communicates with BOManager (for BUSINESSOBJECTS

documents) or WIGenerator (for WEBINTELLIGENCE documents) to process the tasks.

WIADE Server: provides the server interface for the zero administration deployment of

BO. This component launches and manages a “pool” of BUSINESSOBJECTS

processes via OLE Automation under Windows (local calls only), and CORBA under

UNIX. It also manages multitasking and maintains user context.

· WEBINTELLIGENCE SDK

What is the difference between INFOVIEW and WEBINTELLIGENCE?

Infoview gives an instant overview of all the documents available to you in the corporate

database and allows you to view, refresh, manage and distribute documents, but not

create or modify them. To do that you need Web Intelligence or BO Reporter Modules or

BO installed through Web Browser.

Webi user may have any or all of the functionalities available. Create New Webi

documents and edit existing ones. Drill to more detailed levels of data in drillable Webi

documents.

What is the difference between Query Condition and Document filter?

Condition: is applied to the query and limits the data retrieved from the database.

Filter: is applied to the data in the document to hide information and display only the

information that you want to appear.

What can you do withWEBINTELLIGNE SDK?

· Call the Web Panel

· Publish Documents

· Access various file types

· Build a custom web-based report catalog

· Automate WEBINTELLIGENCE login
