In changing world of computerized information systems modeling of business transactions plays an important role. Business transaction can be defined as extended communicative action loop. Using such approach, business processes and new functional requirements may be represented as choreographed sets of extended communicative action loops with established pragmatic and semantic dependencies. In general case, a computerized information system may be of hybrid nature, that is, it may consist of different versions and types of databases. XML streams’ formatting in hybrid information system is discussed in this paper.

In changing world of e-commerce and internet based communication, business transactions and data flows play a key role in successful business management. It is vital to formalize business transactions. Communicative action loop was proposed for modeling these transactions. XML is often used for data exchange. BTP is a specific extended transaction model that allows coordination of resources which are exposed by multiple autonomous organizations. This model relaxes the traditional ACID properties and forms a protocol that can run for long periods of time over the inherently unreliable environment that is the Internet. This project aims to demonstrate if the .NET technology is a sufficiently flexible model to provide an implementation of BTP and whether the functionality provided by the framework is enough to support the complex interactions specified by the protocol.
