Answer :
Question 5. What Are Some Of The Best Practices In Creating Reports?
Answer :
Limit the number of Data Providers Used
Push down operations towards the Database/Universe which means
Retrieve aggregated data instead of aggregation within the document
Do not (accidentally) disable the cache mechanism of Web Intelligence
Web Intelligence has a great caching mechanism for documents that have already been viewed. Using Cache improves the load time of documents; however there are a few functions within Web Intelligence that will prevent the use of the Cache.
These functions are:
Answer :
Yes, you would do that by enabling Data Tracking.
Question 7. How Does Data Tracking Work?
Answer :
Data tracking follows the theme of formatting rules with a difference, that is, its formatting results are determined by comparing two different results.
With data tracking, we can analyze changes over time and are able to track increments and decrements of changes along measures and dimension values.

A subquery is a just a query within a query, whereas a combine queries are two or more queries joined together to form a result set.
Question 11. What Is A Universe?
Answer :
Universe is a semantic layer that shows provides users access to database in a business friendly way.
Question 12. Where Is Data Tracking Enabled?
Answer :
By navigating to the Analysis toolbar and then to the Data Tracking tab, we will be able to adjust the data tracking options.
Question 13. What Are The Two Prerequisites Of Passing Parameters Between Reports?
Answer :
Question 14. How Does Web Intelligence Work?
Answer :
Web Intelligence provides business users an easy to use interactive and flexible user interface for building and analyzing reports on corporate data over the web, on secured intranets and extranets. The Web Intelligence software is installed by your administrator on a web server on your corporate network. To use Web Intelligence from you local computer, you log into the business intelligence portal Info View via your Internet browser. Then, depending on your security profile, you can interact with the reports in corporate documents or edit or build your own documents using a Web Intelligence report panel or query panel.
Question 15. What Are Different Tools Used To Create Or Edit Web Intelligence Reports?
Answer :
You can create or edit Web Intelligence documents using one of several tools:
Question 16. How Is Web Intelligence Java Report Panel Designed?
Answer :
The Java Report Panel is designed for users who need more flexibility with designing report layout and defining formulas and variables. A graphical Formula Editor enables you to build formulas rapidly using drag-and-drop.
Note: The Web Intelligence Java Report Panel is available if your administrator has deployed Web Intelligence in ASP mode and if your administrator has deployed Web Intelligence in JSP mode.
Question 17. How Is Web Intelligence Query- Html Designed?
Answer :
Note: Web Intelligence Query – HTML and On-Report Analysis in Interactive view format are only available, if your administrator has deployed Web Intelligence in JSP mode.
Question 18. How Is Web Intelligence Html Report Panel?
Answer :
Designed for users who need to build basic reports, the HTML Report Panel provides query and report features in a simple wizard-like interface. Each document is based on a single data source and can contain multiple reports, displaying different subsets of information. In addition, the HTML Report Panel is 508 compliant and can be customized for specialized deployments.
Note: The Web Intelligence HTML Report Panel is only available, if your administrator has deployed Web Intelligence in JSP mode.
Question 19. What Information Do You Need Before Logging Into Info View?
Answer :
Before you can use Info View and Web Intelligence you need the following information:
Question 20. What Are The Two Ways In Which Data In The Web Intelligence Document Is Edited?
Answer :
There are two ways to open a Web Intelligence document in edit mode:
Question 21. What Are Data Providers?
Answer :
Question 22. What Is Scope Of Analysis?
Answer :
Note: You cannot define a scope of analysis when working in Query Drill mode. Query Drill defines the scope automatically in response to drill actions.
Question 23. What Is The Functionality Of Cube?
Answer :
The scope of analysis for a query is extra data that you can retrieve from the database to give more details on the data returned by each of the objects in a query. This extra data does not appear in the initial result document, but it remains available in the data cube, so you can pull this data in to the report to allow you to access more detail at any time. This process of refining the data to lower levels of detail is called drilling down on an object.
When you run the query, the dimensions included in the scope of analysis are returned to the cube for that document, but are not projected onto the reports that the document contains. They can be added to the reports at any time, without having to run the query again. Values for the dimensions in the scope of analysis can also be viewed by switching a report to Drill mode, and then drilling down to them from the values displayed on the report.
Question 24. What Is An Ambiguous Query?
Answer :
An ambiguous query is a query that contains one or more objects that can potentially return two different types of information. In a universe, certain dimensions may have values that are used for two different purposes in the database.
For example, the [Country] dimension in the query below can return two types of information:
The role that Country plays in this query is ambiguous. A country value can be either the country where a vacation was sold, or a country where a vacation is reserved. One is existing information (sales), and the other is future information (reservations). To avoid ambiguities in a query, the universe designer identifies the different ways that objects can be used in the universe, and implements restrictions on how these objects can be combined. These restrictions are called contexts.
Question 25. What Is A Context?
Answer :
A context is a defined group of objects that share a common business purpose. This business purpose is usually the type of information that these related objects represent. For example, a sales context is a grouping of all the objects that can be used to create sales data providers. A reservations context is a grouping of all the objects that can be used in reservation data providers. Contexts are defined in a universe by the universe designer.
You can combine any object within the same context to create a query. You can also combine objects in different contexts. If you use an object that is common to both contexts, Web Intelligence will try to determine the context that best fits the other objects in the query.
Question 26. What Are Incompatible Objects?
Answer :
Sometimes it is not possible to use certain combinations of objects in data providers. This situation arises when objects bear no relationship to one another. These objects are called incompatible objects.
For example, the Island Resorts Marketing universe contains the [Reservation Year] and [Revenue] objects, which are incompatible. This is because there is no revenue associated with a reservation. Revenue is generated only when the customer is invoiced. The underlying database structure reflects this; you cannot build a query that aggregates revenue by reservation year because there is no such thing as revenue by reservation year. In other words, the aggregation context that you specified for the [Revenue] object does not exist.
When you build a query, Web Intelligence generates SQL behind the scenes. This SQL is run against the database to produce a result that Web Intelligence displays in a report. For a query to be free of incompatible objects, Web Intelligence must be able to generate a single SQL query to retrieve the data. If this is not possible, the query contains incompatible objects.
Question 27. How Can Queries Be Combined And What Is The Use?
Answer :
You can combine queries in three relationships:
In a union combination, Web Intelligence takes the all the data from both queries, eliminates duplicate rows, and builds a combined data set.
In an intersection combination, Web Intelligence returns the data that is common to both queries.
In a minus combination, Web Intelligence returns the data in the first query that does not appear in the second.
Answer :
When you purge data from a document you remove all data from the document, while leaving the document structure intact. If the document contains multiple data providers, you can purge specific data providers within the document.
Question 29. What Is The Different Table Templates Used In Web Intelligence?
Answer :
The different table templates you can use to display information on Web Intelligence reports:
