Research and Implementation of Object Transactions Service Based on POA in CORBA

This paper introduces the concept of transaction and its properties, including atomicity, consistency, isolation and durability. The two-phase commit algorithm to guarantee the ACID properties is described. The architecture of object transaction service in CORBA is studied. It also addresses the object oriented mechanism of distributed transactions processing by analysis of the objects and interfaces in the specification, Based on portable object adapter the implementation of most interfaces including transaction factory, control, coordinator and resource is presented.
