Native XML database technology of digital distribution network

The construction of ldquodigital distribution networkrdquo needs to connect multitudinous information islands in the entire distribution networks and implement the information integration and resource harmonization of multi-heterogeneous distributed systems. The data sharing and exchanging between correlated systems of distribution in China and the characteristic and advantage of data integration technology based on Native XML Database (NXD) are analyzed. A scheme of constructing data integration platform of the digital distribution network based on NXD technology is proposed, and the platform functions, architecture and key technologies are studied. The integration platform constructs unified digital distribution model and data service bus using XML as information description model, establishes the data warehouse in accord with digital distribution model by the NXD, and realizes information exchange by unified data access mode. The NXD-based data integration scheme can supply excellent connectivity for various applications and well meet the requirement on information integration of digital distribution network.
