[sagarkharpude]

Hi All,

Some months back one interviewer asked me the question like How QlikView is compressing data? How does it work?

I know that data is get compressed upto 70-80% after created the QVD. But i am excited to understand the functionality of how exactly it works?

Thanks in Advance

Regards

Sagar
