> What I do not understand here is how change the val value for each
feature/region. I mean... their spatial geometry is always the same, but
how to bundle them with the right data?
Let me see if I have understood your problem correctly. You have fixed
geometry, but you have constantly changing attribute data.
So, you have two tables.
One consists of UniqueId, geometry
The other is
UniqueId, Attr1, Attr2, Attr3
If this is the correct set up, then you create a view in your database
that joins these two tables on the uniqueId, and then you base the WMS
store on the view, not the table.
