What is QVDs in Qlikview ?

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
