Patterns: Broker Interactions for Intra- and Inter-enterprise

Chapter 2. Fundamental concepts in Process Integration 29

򐂰 Parallel Process Application pattern

and its Parallel Workflow variation

Allows a single interaction from the source application to concurrently execute

multiple series of interactions with multiple target applications

These four Application patterns for Application Integration are summarized in

Figure 2-12. One dimension shows support for concurrent interactions to multiple

target applications in parallel. The other dimension shows support for

non-concurrent interactions to multiple targets in series.

2.5 Application patterns for Extended Enterprise

Using the interaction classification framework introduced in this chapter in

Figure 2-11 as a guide, we observe the following three Application patterns and

their variations for the Extended Enterprise business pattern (also known as

inter-enterprise integration):

򐂰 Exposed Direct Connection application pattern

and its Exposed Message/Call Connection variations

Allows a single interaction from the source application to be adapted and

transported to one partner target application
