Today's global economy requires businesses to expand their processes beyond organizational domains to integrate business partners and collaborators. SOA through Web services is emerging as a framework for bridging heterogeneous business systems over the Internet. Unfortunately it is still limited by many of the constraints of the legacy applications: procedural interaction, data polling and strong coupling of applications. Event-driven systems like publish/subscribe on the other hand provide a flexible interaction pattern that does not require rigid transport or communication protocol. Robust B2B process integration requires a framework that supports enterprise and Internet scale data sharing, point-to-point, push interaction as well as publish/subscribe broadcast based interaction. In our thesis, we accomplish this through a framework the views a B2B network as a streaming database and uses declarative policies to describe data sharing based on an SOA publish/subscribe infrastructure. The key contribution of our thesis is to define a flexible policy approach for describing streaming data. A Palliative Severe Pain Management scenario was implemented to evaluate our framework against BPI frameworks.
