Hi Roman,
1. How do I serve both at the sametime ? What will d url look like ?
By default when you add vector data to geoserver it is served by both
wfs and wms. The services are accessible at the following urls respectively:
http://localhost:8080/geoserver/wfs
http://localhost:8080/geoserver/wms
Consider a feature type called "foo" added to geoserver. You could make
a wfs "getfeature" request to get all the "features" in vector form:
http://localhost:8080/geoserver/wfs?request=getfeature&service=wfs&version=1.0.0&typename=foo
Or you could make a wms "getmap" request to get the features rendered as
an image:
http://localhost:8080/geoserver/wms?request=getmap&service=wms&version=1.1.1&layers=foo&…
WMS GetMap requests are quite verbose. Check one of the demo requests
includxed with GeoServer for an example of all the parameters. Or you
can use the "wms reflector" as a shorthand:
http://localhost:8080/geoserver/wms/reflect?layers=foo
2. if i am to develop a client to process the data i.e wms and wfs. how
will the data be sent ? WMS first then wfs second or what ?
I guess it depends on how you want to make the requests. GeoServer is
fully capable of handling multiple concurrent requests simultaneously.
So if your client is threaded then it can retrieve the data from both at
the same time.
If you intended to ask if it is possible to make a call to both services
with a single requests, the answer is no, you cant do that.
Hope that helps. Feel free to keep on asking questions if anything is
unclear. I also recommend checking out the sample requests bundled with
GeoServer. They do a good job of showing you the anatomy of both wms and
wfs requests.

Do you mean if it should access data via wms or wfs? Without knowing
much i would have to think that wms would be easier. All your
application would have to do is make a wms request, then display that
image. With wfs your application would have to process all the vector
data and render it. More complex.As for a format, definitely postgis. Perhaps another relational
database...something capable of handling transactions robustly. File
formats are usually not the best for that sort of thing.>

I pretty much know nothing about embedded devices... but yes you can use
both wfs and wms at the same time. Probably best to do so as you can
provide a nice base layer with wms.. .and do any stuff that you actually
need attribution for with wfs. If you mean is it possible to server both
raster and vector data the answer is also yes.

You can check out pg_routing... i have seen it been used for doing some
location based routing stuff.Hope that helps.
