Large data Resource description model supporting efficient query retrieval

In view of the problem of large data resource description model which can not support efficient query retrieval in a unified query interface, the extension function is introduced by extending the trace attribute of large data partition management model, in order to support the construction of large diversity data information resource organization mode. On this basis, the inverted retrieval mode which supports high efficient retrieval of large data resources is given, and it is proved that it is much more efficient than traversal retrieval mode and hierarchical retrieval mode. At the same time, the unified query mechanism in dialect mode is given. At present, the large data resource description model has been successfully applied in the unified planning of information resources and the construction of National housing Information System in the Ministry of Housing and Urban and rural construction.
