If I may add: a DataStore is the equivalent of a mapfile layer,
or a layer in any service config. To retake Alexandre's example :<br>
<br>
[DATA] is a 'hospital' table from PostGIS<br>
<br>
[DATA] -> [MapServer WMS Service] -> served as a 'hospital'
layer inside a mapfile, which becomes the [Hospital WMS DataSource] in
GeoPrisma<br>
<br>
[DATA] -> [TinyOWS WFS Service] -> served as well as a 'hospital'
layer inside the config.xml, which becomes the [Hospital WFS DataSource]
in GeoPrisma<br>
<br>
Those 2 DataSource point to the same data in the back-end.
They are now grouped as a single entity called 'Resource' in GeoPrisma.
The authorization to read/write this data is then linked to the Resource,
not the DataStore nor the Services. That way, a single 'Read access
to the Resource to a user' would allow all requests to the WMS service
as well as GetFeature requests to the WFS one.<br>

<br>
A ressource is a group of datastores that represent all the part of the
data.<br>
A data store is a part of the data linked to a service.<br>
Exemple :<br>
<br>
Say you want to show Hospitals on a map: <br>
You'll have a ressource for the hospitals with those datastore for exemple
:<br>
- DS_hospital_WFS that link to your WFS server with
the layer of the hospitals;<br>
- DS_hospital_WMS that link to your WMS server;<br>
- DS_hospital_HTTPRequest if you want to manage your
data via http forms;<br>
- DS_hospital_Cache that will be linked to your MapCache
server;<br>
<br>
So a ressource is to define the content and the datastores are the way
to connect with it.<br>
<br>
Check the samples with the source code, there is a lot of the configs that
are used there.<br>
