Requirements and Evaluation of Protocols and Tools for Transaction Management in Service Centric Systems

As service centric (SC) systems are being increasingly adopted, new challenges and possibilities emerge. Business processes are now able to execute seamlessly across organizations and to coordinate the interaction of loosely coupled services. Often it is necessary to have transactionality for a set of business operations, but the loosely nature of such systems calls for techniques and principles that go beyond traditional ACID transactions. By analyzing existing service composition languages, tools, and needs on a classical example, we provide requirements for transactionality in service centric systems and indications for developing SC systems transactionally capable.
