An application system for business

Share |

What do banks, trucking companies, fashion colleges, school districts, construction companies, casinos, automobile manufacturers, confectioners, luxury watch makers and a cantaloupe melon distributor have in common? They have an ISV application that runs on IBM i.

By the time the first AS/400 server was shipped in 1988, more than 2,500 software packages from ISVs were available for the platform—the biggest simultaneous applications announcement in computer history. As a result, it quickly became one of the world's most popular business computing systems.

One of the key advantages of IBM i for ISVs is that they can rely on a common database and middleware foundation for all of their clients around the world. That makes testing and support far simpler than if clients had an operating system with assorted database and middleware variations. IBM i also has a track record of investment protection and application compatibility that has not been exceeded in the IT industry. An application that ran on the System/38 in 1979 would run on the AS/400 without recompilation in 1988, and would still run today—25 years later. The AS/400 server was first and foremost an application system, and IBM i remains so today.
