ISPF doesn't maintain DB2 tables; DB2 does.
Why *isn't* it a limitation of ISPF? ISPF is the user interface to the
mainframe, in just the same way as Windows is the user interface to the
PC. If I'm working on my PC and I click a PDF document, Windows opens
the Adobe reader. If I click an XMI file (which MicroSoft might not even
have heard of), Windows launches the XMI browser I downloaded. I can
click MP3 files, REXX files, JPEG files (etc etc) and Windows launches
the appropriate tool.
The mainframe is a platform to be proud of. You should expect the
interface to do more than what other operating systems can do, not less.

Windows does not do this on its own. Windows has no clue how to read a
PDF file. You have a program that knows how and this program tells
Windows when you see a file that ends in .pdf then you need to execute
me. Windows provides the base that allows you to write a program to do
what you want and the methods to launch that program. Windows does not
automatically know how to handle every file type. You need to tell it
what to do.
So, just like in Windows, TSO provides you the ability to write any
program you want to do anything you want and you can use ISPF on top of
your program.
