I know this request is going to sound strange, but can someone tell me how
easy/difficult it is to change things from an IBM-type database (like IMS),
to a UNIX-type database (like INGRES, UNIFY, ORACLE). I'm thinking about
porting a software package from an IBM environment to a UNIX/C environment,
and I'm pretty sure the package uses the IMS database. Any and all
suggestions and comments (other than flames if this is a stupid question)
are welcome. Please e-mail responses to me at cbosgd!tgt. Thanks!!

The basic problem that you will face will be mapping a hierarchical data model (IMS) to a relational one (ORACLE, UNIFY, etc). "Introduction to Database Management Systems, Vol 1" by C.J.Date is a good reference on the various data models. --Michael Bruck Intel CAD, Santa Clara, CA The Above views are personal... usual disclaimer.
