One of the fundamental problems in complicated system environment is the mechanism of data interaction and sharing between heterogeneous data sources. The known solutions, using middlewares to unify data formats, are not reliable due to the tightly coupled architecture, poor portability and reusability, large update latency, etc. To solve this situation, we herein introduce the concept of Service Data Object (SDO) into a platform of aircraft collaboration designing, to build a data integration mechanism among the multidisciplinary applications that collaborate the designing process. We propose a Global Uniform Model Generation Algorithm (GUMGA) to automatically generate the uniform data format of the applications, using XML as a bridge among heterogeneous data sources. A case study is implemented and tested to prove that GUMGA can shield the isomerism among data sources, and provide an effective and extensible solution to deal with the data integration problem in complicated systems.
The idea of service-oriented architecture is always used for modern software system designing. SOA offers methods for system development and system integration. In order to meet the demand of dynamic business, improve the quality of service and quality of experience, this article increases the dynamic service execution engine on the integration layer based on industry standard architecture model of S3. We propose a Dependable Adaptation Dynamic Enterprise Service Bus(DAD-ESB) and design Dependable Service Select Algorithm(DSSA). At last, a performance evaluation experiment between static and dynamic dependable service composing is tested. The experimental results show that the dynamic dependable service composition has the high advantages, and with the dependability increasing, the success rate of calling is much higher.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
