Most of the financial industries like banking sector , insurance ,Retail chains use mainframes for their business,the techonology which was introduced around 40 years back.Todays techonology deals with object oriented concepts like C or JAVA which is much user friendly and easy to implement business requirments.
Why industries are not switching over to these latest techonologies where it's easy for a programmer to code and further more maintenance cost are very less when compared to mainframe techonolgy?
sorry to make such an idiotic mistake,Thanks for the correction
Rahul, I guess is talking about M/F using proprietory technologies, while the current OO world uses the Object Model (Everything is seen as Objects).
We must look from the "Users perspective", they are now likely to be familiar with a GUI Desktop, than a Green Screen Telnet interface.
This is of course "push" on to the Users through the years of marketing and improvements from those who seek to dethrone the M/F technologies.
I guess M/F has also evolved in the last 20 years, not to dethrone the Desktop users, but to work along side with them.
Ease of Maintenance is always the issue, due to rapid changes in the business world and the "push" or competitive development environment.
Do hope this help clarify the link between M/F and OO world.
I've worked on banking apps and I can assure you they most certainly do use modern software techniques.
True, many of the core programs are still the old COBOL and SNOBOL ones; but they work so why mess with them?
Also, as was stated by FunFunkyFritz, the cost to translate the billions of lines of code involved would be astronomical. Just remember the Y2K threat. Something as relatively simple as that was deemed by the large institutions to be too expensive to fix.
Business business and business again. converting from one core system, such as main frame as not as easy as it seems! you can't just flip a switch and go live. converting from M/F to OO systems as a costy and incrusiating process, and often things go wrong, these all lead some businesses to buncrapsy!
However, the convertion is a happening thing, more and more businesses adopt Enterprice Resaurce planing systems, so probably soon main frames will extinct.
