Re: Changing database to SQL from DDS

One other point of view, to my mind, is that both DDS and SQL are fine but
not very modern.   
 
The tool to define and change files should include the entire gamut of file
defintions, cascading deletes, triggers, referential integrity, and
constraints.  The way we have to do all these piecemeal today just makes no
sense anymore.  Maybe Ops Navigator will get us there?

In the IBM Midrange world DDS is the standard. Having SQL there for 
compatibility sake for the rest of the world is moving the box in the right 
direction. This is similar to adding Java to the box and forcing us to 
abandon our current development language, just because it's the "new world 
standard."

By eliminating DDS (from a practical standpoint) you've now shifted the 
cost of redevelopment onto the customer anyway, so we pay either way! I 
think that it would cost us a lot less for IBM to make the enhancements 
than for us to have to redevelop major systems. JMHO.
