How to view the table structure in DB2 database
I am using Aquadata Studio 12.0.23, which is several versions short of the newest. So your experience may be better than mine. I found that the best way to get an overview was to use the ERD generator. It took a couple of hours, since normalization was not a concept used in the design of this database almost 30 years ago. I was able to get definitions for all of the objects in a few hours, with a file for each.
