The introduction of service-oriented computing has created a more dynamic environment for the composition of software applications, where processes are affected by events and data changes and also pose data consistency issues that must be considered in application design and development. This chapter addresses the need to develop a more effective means to(More)
This paper defines the concept of Assurance Points (APs) together with the use of integration rules to provide a flexible way of checking constraints and responding to execution errors in service composition. An AP is a combined logical and physical checkpoint, providing an execution milestone that stores critical data and interacts with integration rules(More)
