There are thousands of Legacy applications that need to be
migrated to the web because they still perform useful work
and provide valuable data. How these applications are
migrated depends on the current architecture of the system,
the service or reports that it provides, the database
the system maintains, and the look and feel appropriate for
its intended web users.
Tagg Associates has more than 20 years experience
processing data on the IBM OS/390 and its predecessor
systems. This includes:
- developing systems utilizing SMF and Logrec data and
the DB2 relational database
- using VSAM and flat file systems
- using TSO/ISPF, VTAM, Unix System Services, operating
system extensions, and supervisor routines
- working with IBM legacy applications written in Java,
Cobol, Assembler, REXX, CLIST, and (to a limited extent)
C and Fortran
This extensive knowledge of legacy systems, combined with
experience developing web applications
(see
ExploreMVS background information), provides Tagg
Associates with an exceptional set of skills for making
IBM legacy applications accessible on the web.
Some approaches to moving legacy applications to the web
that Tagg Associates has used, or is working on,
include:
- wrapping the application within an interface
that converts legacy inputs and outputs to web
protocols
- creating a web user interface for the application
- converting the legacy application into a web service
using the SOAP protocol
