An approach of integrating CORBA and XML for traffic data management

The traffic data are heterogeneous, distributed, which makes traffic data management much more difficult. Since it is becoming more and more important and imperative to manage traffic data nowadays, in this paper, a distributed architecture in accordance with CORBA is designed to realize traffic data interchange. XML is used to provide a uniform description of traffic data. A universal approach is supplied to clear up the heterogeneity of traffic data. The integration of traffic data description and distributed architecture comes true by using the mapping between XML document and CORBA IDL. Finally, this paper puts forward an architecture for the management of traffic data with three-layer structure by integrating XML and CORBA and presents a case study of this architecture called information query system for Beijing Public Transportation.
