Consistency management for complex applications

Consistency management is important in many complex applications, but current languages and database systems inadequately support it. To address this limitation, we defined a consistency management model and incorporated it into the PLEIADES object management system. This paper illustrates some typical consistency management requirements and discusses the requirements in terms of both functionality and cross-cutting concerns that affect how this functionality is provided. It then describes the model and some design and implementation issues that arose in instantiating it. Finally, we discuss user feedback and future research plans
