Yanhua DU · Zhongguo tiedao kexue · 2007
Aiming at the complexity and flexibility in the process integration of 5T system,we presented a model-driven web services composition methodology for process integration.In this method,we adopt service-oriented architecture and via Web services composition to realize process integration.We use UML model design Web service composition and define the mapping rule to realize the code generation from model automatically.Firstly,we introduce the description rules for web services composition modelling and the mapping mechanism from web service composition model to executable code.Then we use this method to construct an integration process of alarm judgement and failure disposal in 5T system and map the model to code automatically.Instance shows that the model-driven web services composition method could effectively reduce the complexity of 5T system integration,and enhance the adaptability of integration system and interoperability between hemogenous systems.
