Simply, a QVD is a compressed version of a QVW which makes data processes easier to handle.

For instance, we currently use Extract Scripts to produce QVDs which we then incorporate into front end QVW applications for end users to consume.

Hi,

QVD is the qlikview data file which stores the table data. The stored data is in compressed format.

QVW is a QlikView application. This will store the data along with Data model and Also contains the dashboard and visualization of reports.

qvd and qvw are files

qvd is a like a table in a database but in QlkView proprietary format

useful for fast load of data (incremental load) in Qlik and/or for non trivial data architecture (2/3n layer)

qvw is

- nothing when you create it

- script, to load and transform data from source (database, web, ftp, qvd too as qvd is a table); like an etl

- in memory database: after you execute the script, usually you have your qlik db in memory

- user interface (charts) built on the in memory database

QVW : Qlikview files : a file extension which stores the qlikview dashboard and the data loaded in it.

QVD: Qlikview Database files: which stores data in compressed format, this is used for optimization so that you need not to hit the database again and again. which ultimately saves your response time.
