QVD or QlikView Data File is a very powerful feature of QlikView.
QVD is a native QlikView format. It can be only written or read from QlikView.
One can connect to the data source and export data in the table in a QVD.
Advantage of QVD over other Data Sources:
– Once data is exported in the QVD you don't have to connect to database. Your data will reside in QVD.
– Reading from QVD is 10-100 times faster than reading from Data sources.
– Consolidating data from multiple data sources and databases.Create multi layer QVDs to create a robust data model.
– Incremental load can be implemented only by using QVDs
