Automatic Integration of Service Oriented Systems

面向服务的系统是构建在面向服务的体系结构（SOA）上的信息系统，或者是包装为Web服务的遗留系统，这些Web服务可以通过WSDL接口调用。SOA作为一种新的系统范例，承诺了互操作性、可伸缩性和可组合性。 面向服务的系统应该快速组合成一个新的应用程序，以实现新的业务目标，并在工作完成时解决自己的问题。如果在运行时出现任何故障或业务目标发生变化，面向服务的系统应该发展并适应这些变化。我们需要自动化的方法来集成面向服务的系统，以实现这些先进的功能。由于服务的接口和内部业务流程都是独立设计和开发的，面向服务的系统的自动集成仍然是非常困难的。我们认为自动化的服务组合是实现集成的基本途径。在现有的自动化服务组合技术之上，我们希望不仅考虑没有内部行为的服务，而且考虑具有国际行为的服务;不仅要实现功能性需求，而且要实现非功能性需求;不仅要考虑接口，而且要考虑参数的数据值;不仅要考虑SOAP服务，而且要考虑其他类型的服务，例如RESTful服务。在自动化服务组合的基础上，我们将研究适应机制来应对变化。我们对云和移动的设备上的服务特别感兴趣，并将研究与这些服务的集成问题。 我们将通过开发理论，方法和工程工具来支持面向服务的系统的集成来推进这一领域。我们将与我们的工业合作伙伴一起将我们的研究成果应用于真实的世界。

Service oriented systems are the information systems built upon Service Oriented Architecture (SOA) or the legacy systems wrapped as Web services that can be invoked through WSDL interfaces. SOA as a new system paradigm promises interoperability, scalability, and composability. Service oriented systems should fast compose into a new application to fulfill new business goals and resolve themselves when the work is done. If any faults occur or business goals changed at run time, service oriented systems should evolve and adapt to the changes. We need automatic approaches to integrate the service oriented systems to realize these advanced features. As the interfaces and internal business processes of the services are independently designed and developed, automatic integration of service oriented systems is still very difficult. We think automated service composition is a basis approach to achieve integration. On top of current automated service composition techniques, we want to not only consider services without internal behavior, but also service with international behavior, not only achieve functional requirements, but also achieve non-functional requirements, not only consider interfaces, but also consider the data values of the parameters; not only consider SOAP services, but also the other types of services, e.g. RESTful services. On top of automated service composition, we will study adaptation mechanism to react to changes. We are especially interested in services over clouds and mobile devices and will study integration issues with these services. We will advance this area by developing theories, methodologies, as well as engineering tools to support the integration of the service oriented systems. We will apply our research results in real world with our industrial partners.
