Service-oriented architecture (SOA) has the potential to provide solutions for enterprise
application integration (EAI) problems. While core service platform technologies
exist, methodological approaches that link the business domain with the platform infrastructure
- a prerequisite for an EAI solution - are only beginning to mature. We present
a framework for integrating service-centric software systems that emphasizes service architecture
as the key to the application integration problem and that proposes a service-
centric integration architecture layer to coherently bridge the gap between business
and platform layers. Domain models act as drivers of the architectural development and
integration process. A dedicated and empirically developed service-specific architecture
solution, based on an adaptation of the QUASAR Enterprise methodology, utilizes service
and architecture identification techniques.
