OL achieves this trough its Strategies, like BBOX strategy

I think that strategy doesnt work if ur vector layer gets data from
some GML file, it has to  fetch it from some WFS server (correct me if
im worng)
Its not hard to make one, take a look at geoserver.org.
You dont have to put date in database if u dont want, you can put it
in one shape file, its easy try it.

Hope it helps,
Ivan
