Explain Qlikview architecture?
Answer: QlikView deployments have three main infrastructure components:
1.QlikView Developer : Is a Windows-based desktop tool that is used by designers and developers to create
1) a data extract and transformation model and
2) to create the graphical user interface (or presentation layer).
2.QlikView Server (QVS) : Handles the communication between clients and the QlikView applications. It loads QlikView applications into memory and calculates and presents user selections in real time.
3.QlikView Publisher: Loads data from different data sources (oledb/odbc, xml, xls), reduces the QlikView application and distributes to a QVS.
Because QlikView Server and Publisher have different roles and handle CPU and memory differently it’s considered a best practice to separate these two components on different servers.
