What is the use of CommandBuilder?

 CommandBuilder builds ''Parameter'' objects automatically.

Example:

Dim pobjCommandBuilder As New OleDbCommandBuilder(pobjDataAdapter)
pobjCommandBuilder.DeriveParameters(pobjCommand)

If DeriveParameters method is used, an extra trip to the Datastore is madewhich can highly affect the efficiency.
