For the same functionality, DB2 will require about an order of
magnitude more cycles than IDMS. Always been that way. Don't expect it
to change.
But it takes two orders of magnitude more labor effort to add an
equivalent piece of new functionality to an IDMS based application than
to a DB2 application. Always been that way. Don't expect it to change.
