Research and Application of Data Integration in Aircraft Designing Based on SDO

摘要

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.
