Hi Seenu, the qvw file also contains the data, Section Access can be used to limit the acces to data and the same section access or Windows permissions to access the document.
If the document has a scheduled reload on server, the server will do the connections to refresh the data.

When you load the data into QVW the file contains all of the data you have loaded as per loading script.
This means you can use the QVW even if you separated it fromthe server and opened it on another server.

Hi,
Welcome to qlik!
Yes it contain only that visualization object, expression, script , variable etc but not the data. qlikview/sense both are using in-memory concept (i.e all qlikview/sense qvd, other data are stored in RAM) so it will be faster than the traditional BI tool ( remember to use binary load app at presentation this method is much more faster)

The Qlikview document holds the data when you refresh or deploy on server for auto refresh. The two main functions of Publisher is to Reload the data and Distribution of data from source documents to User documents which further viewed in Access Point when user access the dashboard. Hope this makes sense.

Qlikview Doc will hold the data when you refresh it or send it on server.
Functions of Publisher are mainly to reload and publish the data/Distribution task to user docs from source docs.
This user doc destination can be configured through QMC.
