Process-Centric Architecture for Enterprise Software Systems

Chapter 8

The Approach

8.1 Objectives

■  To understand how the architecture of an IT system looks in the process-centric style

■  To appreciate the different components and their roles in the architecture

■  To be introduced to the architectural design behind process-centric architecture (PCA)

8.2 A Typical Manifestation of Process-Centric Architecture

8.2.1 The Architecture

Let us take a look at an architecture that embodies the PCA style. This example involves order processing.

Figure 8.1 shows the process model of an order process. The static and dynamic views of the architecture are shown in Figures 8.2 and 8.3.

In this manifestation, we have the following components. The process engine of a business process management system ...
