Ok but the Amiga was introduced only much later. I am talking about 1982 up to 1984, and the Amiga only appeared in 1985 I think.
In those days I worked in a small company that developed middleware to run small business applications on Unix systems like the Fortune Systems 16:32, the NCR Tower, the Convergent Technologies Miniframe, etc.
The package included a screen manager (to enter data in screen forms a form at a time to be submitted for processing, like IBM systems did), a database manager (actually more like a keyed filesystem manager with locking), reporting/printing manager, communication with peer systems and local devices, etc.
The whole thing of course was very compact and efficient because in those days you typically had 10 users on a system with 2MB RAM and 40MB disk.
