Modern 4GL systems tend to turn into really object-oriented environments
which seem to be suited quite well to realize business information
systems (BIS). BIS should support the accomplishment of daily enterprise
work. Such systems are required to handle a huge volume of data, assure
data integrity, cope with high input/output intensity, incorporate
transaction management and provide enduser-oriented interfaces.

Existing object-oriented analysis methods fit rather well to the purpose
of BIS development. Currently available object-oriented design methods,
however, do not properly take into account the typical BIS
characteristics. This paper proposes a powerful and flexible generic
object-oriented process model for BIS development with 4GL. This process
model particularly focuses on the adjustment of object-oriented design
activities to the context of BIS development in connection with 4GL and
on its incorporation into the overall object-oriented BIS life cycle.
The applicability of the proposed process model will be demonstrated by
some examples using CA-OpenROAD as underlying 4GL technology.
