#79 Different levels of Data Models

There is a logical connection between the core business processes and the information systems themselves, although not everyone may think so.

It should be noted that although the work is divided into levels and logical steps, these can all be accomplished by the same team and in a single session. In many cases, for example, through dialogue, this is very effective and sensible, but in larger environments, of course, it may not make sense to use senior business management time for all of these steps.
