Hi,
I am preparing for Qlikview developer interview. One of the common question, I have found is related to Qlikview architecture “What is difference between 3-tier and 2-tier architecture?”. Please help me with detail description about the Qlikview architecture!

@Satish,

When we deploy Qlikview, there is multi layer of deployment.

1st Tier - Interaction with raw data directly. Raw data is getting loaded.
2nd Tier - QVD is transforming in the business requirement and data model is created.
3rd Tier - Reading the all QVDs from 2nd tier and make a QVW or may be any binary load.

For more detail, you can refer attached document:
