Statements

1. Object oriented programming of reliable business applications should be carried out with Java now.
2. Object orientation offers a number of extraordinary opportunities, but - for the time being - must not be mixed up with Rapid Application Development (RAD).
3. It is one thing to acquire the paradigm of a new programming language, but it is another thing to realize all customary standards
4. We have programmed COBOL and RPG on AS/400 and S/36 like you for about 13 years now, so we know your needs.

You have optimized your AS/400 applications over the years and the users appreciate the defined standards. You are aware of the effort required to create equivalent applications with new development tools/ in a new development environment. You also know what it means to handle large quantities of data. Nobody must tell you about the concept of traditional PC programs.

We have switched to Java development in June 1997, and we have oriented at the requirements of midrange data technology. The result is a Framework that covers all essential issues of midrange application development and at the same time is fully expansible. The standardization already available in COBOL can be realized more thoroughly with Java.

This reliable Framework offers RAD according to the requirements of midrange data technology!

Sample: F4 on key table

Let’s have a look on a prompt on a key table, e.g. Department. Maybe you had an own DSPF, maybe you only had a screen format with subfile, maybe you had a whole program with "scroll function" - you know what I mean. In this Framework there is only one line:

Translation: As next field on the window / on the current Tab, put a ComboBox. Fill this ComboBox completely with the column "department name" of the table "department"; use standard sorting for that. The entity, which is managed in this window, points at you with the field "department ID". Please, manage the following without further assistance:

• If the user selects a new entry of the entity to be managed, mark the the associated department.
• If the user selects another department, update the department ID in the entity to be managed.
• If another process changes, deletes or adds entries of the departement table, update yourself immediately.

It is true that one has to get accustomed to it, especially since this example has been separated from its context, but you might have an idea now of the possibilities Java provides - provided that the preparatory work is done.
