Answer / neha

DataAdapter helps in updating back the database through its
update method. That is,
adapter.Update(ds);

It does this even when the connection is closed. Actually,
data adapter opens connection object to update the records,
after the records are updated, the connection is closed
again. Since there must be some path from application to
database in order to update and retrieve records. Thus, to
do this, adapter uses the connection.
