Not sure what you mean, WMS or WFS client or just a web browser?

Yes, but it depends on if you are reading from a database with a
"spatial" extension that directly supplies geographic data or if you are
reading simple attributes, such as the x & y coordinates of a point, and
need to create a geographic feature for display.

If the data is dynamically handled directly in the RDBMS and MS uses
that data directly, ie. PostGIS then the database handles the "dynamic"
nature of the data and MS simply uses what the database supplies.
If the data comes from a shapefile and you want MS to handle the changes
to the data then you can use some flavor of MapScript to program that.

AFAIK, yes.
