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
