[Mapserver-users] Wms or Wfs

[publiek at home.nl]

Hello all,

I'm trying to understand what WMS / WFS do.

We have a database with employment data per location.
We also have a polygon database (postgis/postgresql).

It is possible to use wfs to get a table depending on where the user clicks on the map? I believe the mapserver asks postgresql the relevant data?

And with wms you also get the image? 

Am i correct on this? And how could i implement this? Any tips / pointers?
