Some thoughts about your questions.
a) To create the impression of a moving sea surface, one way to go is to
move the mesh on which the seatexture is mapped locally up and down. But
it is hard to find a movement pattern that looks realistic enough.
The flow of water can also simulated by switching between two different
waterfall-textures.
b) Define the path as a spline and let the DCS follow this spline.
c) There are several routines to pick and identify objects/polygons in
performer.
d) External database access is slow, so you have to 'freeze' the user in
the current state until the request is done. Seems to be unappropriate
in a realtime simulation.
The SQL-structures could be places in the userdata portion of a geoset,
but you have to include all the interfacing to the remote computer
application layer.
Maybe there are more ways to get it done, but performer is basically designed
for realtime animation
