11.1 Patterns for e-business
Patterns for e-business are a group of reusable assets developed to facilitate
and speed up the process of solution design for e-business applications. Their
purpose is to capture and publish e-business artifacts that have been used,
tested and proven. The information captured by them is assumed to fit the
majority, or an 80/20 situation.
Depending on the pattern used, we can talk about logical (based on conceptual
modules and building blocks) or physical/runtime architectures. Patterns are
usually used as a generic type of solution that can address a family of problems.
It needs tailoring to make them an effective solution and they must be
customized to include all the aspects of the IT environment where the solution
will be used.
A number of different patterns has been developed and is still being extended for
e-buiness applications. The Patterns for e-business layered asset model is
shown in Figure 11-1.

This is the CIO’s view of the business problem. It defines business processes
and rules, actors of the system, user roles, existing and future support modules
as “architectural” building blocks.
