Re: Question about UDB on iSeries

I don't know how stable your current applications are (i.e. no new
development), but if your current job is to simply maintain the
database, then no - you won't have much to do.

On the other hand, if you do new development or major enhancements to
the existing system, then your selling point will be the ability to
focus on new development exclusively.  the productivity gains will be
well above what you're used to.  in other words 'heavy techies' are
very much at home on iseries.

As far as application development is concerned, your biggest learning
curve will probably be in the following 2 areas:

DDS a fixed format data definition specification 'language'- required
for presentation I/O - green screens.  (Printer output can be done
this way as well, but not required).    DDS is also the 'native'
method of coding data definition specifications  (tables, views, etc).
  as was stated previously, you can also do data definition via SQL
DDL.  Pick your poison.   But if you're doing green screen
programming, you will need to learn DDS.

CLP - the job control language (compiled) used for stringing commands
and programs together into a single job - a JCL equivalent but does
not resemble it in the least.

hope this helps
