5. Question 5. What Are The Differences Between Personal, Shared And Secured Connections?

   Answer :

   A Personal connection is created by one user and cannot be used by other users. The connection details are stored in PDAC.LSI file.

   A shared connection can be used by other users through a shared server. The connection details are stored in SDAC.LSI file in the Business Objects installation folder. However one cannot set rights and securities on objects in a shared connection. Neither can a Universe to exported to repository using a shared connection.

   A secured connection overcomes these limitations. Through it rights can be set on objects and documents. Universes can be exported to the central repository only through a secured connection. The connection parameters in this case are saved in the CMS.

22. Question 22. What Are The Query Filters?

    Answer :

    Query filters are used to limit the rows returned in a WebI document. Query filters allow you to hide the data that you don’t want to show to specific people and also limit the size of .wid document. When you run a query, it only returns the rows that meet the query filter definition.

    Below are the key features used in Query filter:

    You can retrieve data as per specific business requirement.

    You can hide the data that you don’t want specific users to see in a WebI document.

    Limit the size of WebI document of network and hence provides performance optimization.

    Example: Being an Area Sales Manager for NY, you want to see margin values for your region and Sales universe contains data from all the regions in United State. Also you only want to see data from the stores in NY where sales margin is greater than 100K USD in 2nd Quarter Q2 2015.

25. Question 25. What Is Context And How They Are Created?

    Answer :

    Context defines a particular join path between tables or a specific group of joins for a particular query. Any objects created on a table column which belong to specific contexts is naturally compatible with all other objects from same contexts.

    Contexts may be created using detect contexts feature or manually. They are generally created based on logical calculation and business requirements, hence the detect context method is not very effective. To manually create a context Go to Insert Context, give the context name and select the joins that should be present in the context. For a universe contexts should be created in a way that all joins(except shortcut joins) fall in at least one context.

26. Question 26. What Is Aggregate Awareness Function? Why Do We Use It?

    Answer :

    Aggregate awareness function is used in scenarios where we have same fact tables in different grains. Using this function we can define only one object for the measures in the fact tables.

    aggregate_aware(highest_level,lower level)

    We also need to define dimensions for associated granularities and define their incompatibilities with the corresponding facts through the aggregate navigation. This is accesses through Tools → Aggregate Navigation.

    Use:

    They are used to enhance the performance reports by utilizing arrogate tables available at database and are applied at Universe level as function.

    Example

    Consider a Geography hierarchy, you have Country India and State defined as Delhi. Now if you use this geographical hierarchy in report and want to analyze Number of Units sold at each level for different categories, then hierarchies allow you to use Aggregation at country level and if you drill down to state level, for each state too.

30. Question 30. What Is Difference Between Break And Sections?

    Answer :

    Section breakup the data into multiple cells that are called Section headers and Each Section header contains a value for dimension and data corresponding to dimension value.
