Abstract

Provided are transaction processing systems and methods enabling interoperation between data processing resources which implement different transaction processing models. The systems and methods also enable resources which were not created using object oriented programming techniques to interoperate with object oriented programs and to utilise object orientation concepts. The systems and methods allow transactions to be controlled using consistent operations across multiple object oriented transaction services. A set of object classes is implemented on a transaction processing system, the object classes including: an object oriented wrapper (300) for an existing system interface; an interface implementation (310) which corresponds to a different transactional model from that of other system resources; and a transaction class (320) which maps transactional operations of one model to transactional operations of the second model, while taking account of transactional operations which are within transactional scope according to one model and outside transactional scope according to the second model.
