Interview Questions for Qlikview Designer-2
Question.1 What is calculated dimension?
Answer: Charts in QlikView require dimensions. Dimensions provide context to measure or expressions. Sometimes these dimensions exist in the data and sometimes need to be calculated. Such dimensions are called calculated dimensions. Calculated dimensions are created in the chart, by using “Add Calculated Dimension” or by simply editing the existing dimension. The calculated dimension can be an expression using conditional statements and functions.
Question.2 What are synthetic dimensions?
Answer: Synthetic dimensions are the dimensions which are created by the developer using the synthetic functions. These dimensions are not based on the fields present in the data model.
ValueList and ValueLoop functions are used to create Synthetic dimensions.
Question.3 What are triggers in QlikView desktop?
Triggers are used to set Action on an event. These Actions execute when a specific condition is met.
Trigger types are Document event trigger, Field event trigger and variable event trigger.
The trigger is configured from menu Settings/Document properties and selecting Triggers tab.

Question.8 How you will create an application for mobile devices like iPad?
Answer: QlikView does not have any specific objects for iPad. For iPad, a dashboard should be developed using the same objects, but for a different screen resolution. The focus should be given to objects that will be more visible on iPad. For e.g. containers should be used instead of displaying charts separately.
