[OpenLayers-Users] Best way to have different information shown on the same geometries

[Phil Scadden]

 > 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.
