A model of computer software environments is presented based upon
(Environment 0: hardware (eg: IBM machine))
----------------------------------------------------------------------

Environment 1: operating (& network operating) system software (eg: WinXP,
Unix)
Environment 2: RDBMS/DBMS software (eg: SQL Server, DB2, Oracle, mySql)
Environment 3: client-server application systems software (eg: university
college management application,
new & used car sales management, intellectual
property management application, etc)


Q1: How representative is the above classification system of environments
for computer software
types, as to be found in most mid-range to large organisations today
(ie: running dbms software)?

Q2: Is there an existent classification system (eg: Does Date present a
similar classification of s/w,
and if not, is the above consistent with Date) --- note: I have yet to read
Date but will.)



Thanks for any feedback.

Depends on what the heck you are trying to model. There are **many** layers
in each of the "environments" you have listed.

I am trying to model the overall generic (multi-vendor?) computer systems
software environment encountered at your typical mid-range to large
organisation.


Yes. That is so.

I am interested whether those **three** (conceptual) layers are OK and
can validly capable of containing and representing the global set of layers.

There may be other terminology in this area,
that I am not aware of ... ?

A generalised computer software environment
typically found in any organisation running an
rdbms/dbms and attendent application software.
