So far



Mainframes is a very stable
environment
It has been there in the Software
Industry for more than 40 years
No new technology can totally
replace Mainframes because of its
architecture and efficiency
Current trend



Around 80% of Mainframes projects
are maintenance projects
Only 20% or less are development
projects
The reason being the cost factor. The
hardware maintenance cost and the
initial investment required is too
high.
Current trend


Migration projects are the current
trend in the market
Reasons:
User friendly screens
Maintenance cost
Future

A survey to determine the current
demand for mainframes found that
more than half of the respondents
still have major applications running
on mainframes
In DBA

We are working on mainframes right
from the day company started.
We are experts in PL/I, IMS but we
have also worked on COBOL, DB2
Projects.
