Naming is an important, but frequently overlooked, aspect of software systems. Usually, naming appears combined with other issues, e.g. distributed communication technology. This paper treats naming in isolation. It presents a naming design pattern which abstracts several naming policies and an object-oriented framework that can be customized to support(More)
We propose an object-oriented approach to the development of distributed applications emphasizing separation of concerns. Our approach combines the needs of transparency , encapsulation of distribution issues, and support for non-traditional models, where cooperation and sharing are desired. The development process is constructive, thus allowing partial(More)

Business objects are object-oriented representations of organizational concepts, such as resources and actors, which collaborate with one another in order to achieve business goals. These objects exhibit different(More)
In recent years we have witnessed the development of adap-tive workflow management systems. These systems offer an extended set of features to support both ad-hoc and evolutionary changes, while ensuring correctness of process definition and their running instances. Ad-hoc and evolutionary changes impose new access control requirements, which have been(More)
