Abstract

In the context of building software systems, Service-oriented Systems (SOS) have become one of the major research topics in the past few years. In SOS, services are basic functional units that can be created, invoked, composed, and if needed deleted on-the-fly. Since these software systems are composed of different services there is no easy way to assure the Quality of Service (QoS), therefore, formal specification of both functional and extra-functional system behavior, compatibility, and interoperability between different services have become important issues. As a way to address this issues, resource-aware timing behavioral language REMES was chosen to be extended towards service-oriented paradigm with service specific information, such as type, capacity, time-to-serve, etc., as well as Boolean predicate constraints on control flow guarantees. In this thesis we present a design framework that provides a graphical user interface for behavior modeling of services based on REMES language. NetBeans Visual Library API is used to display editable service diagrams with support for graph-oriented models. A textual dynamic service composition language was implemented, together with means to automatically verify service composition correctness. We ensure also an automated traceability between service specification interfaces, where both modeling levels are combined in an efficient tool for designing SOS.
