4⟩ Explain difference between detect alias and detect context?

We should use Detect Aliases and Detect Contexts to formally identify and resolve loops.

i.e.if a loop contains only one lookup table then the loop can be resolved by detecting the alias.

if a loop is having 2 or more fact tables(multiple fact tables) then the loop can be resolved by detecting context

Detect alias: resolving fan trap

Detect context: resolving chasm trap

13⟩ Can you please explain the difference between condition & filter?

Conditions: these retrievals the data based on the condition (universe level)Filter: it brings the data and filter; performance will be slow (report level)

Filters - are used to restrict the number of rows in the output.

Conditions - It wont reduce the Number of Rows, but you can show up data based on some validations.

For Eg: select cust_id from customer where cust_name like 'A%'

Filter is Cust_name like 'A%'.

15⟩ Described about thumbnail?

BusinessObjects Enterprise lets you preview a report using thumbnails. You can request the server to take a snapshot of the first page of the report and return it to the browser as an image file. This image can then be displayed as part of the Report Details page.

To retrieve a thumbnail, a separate page needs to be created because the code that writes an image to the screen erases any text that may have previously been there.
