Abstract
Aimed at the heterogeneous system data integration problem in risk management,equipment safety management and occupational health management,based on the model of third information flow,system framework which was divided into data physical storage layer,data logic storage layer,application layer,control layer and user layer was designed.Focused on data logic storage layer and control layer in the framework,the method of implement was researched.In control layer,the technology of single sign-on was used.The Central Authentication Service (CAS) open source project was used as a platform,through the way of service tickets,authentication and authorization of the user identity were achieved.In data logic storage layer,the data request process was divided into request,distribution,access,collection,arrangement and response.In these six steps,user request was transformed into business requests of heterogeneous system,the multi-source data was merged into a single source data which used Extensible Markup Language (XML) to form a unified format,the heterogeneous system data integration was implemented.With this design,the problem of the heterogeneous data integration extraction,write-back and safety control is solved,information islands is eliminated,the maintainability and expandability of system is improved.关键词
