| Abstract: | The individual mineral rights fieht verification data has the characters of small- amount, large-nLmlber, heterogeneous, and multi-resout＇ces. It is a challenge task to quickly query and extract data from massive and heterogeneous mining right fieht verification data. This paper discuussed and established the scientific and reasonable data model, and put forward the integrated application of database technology, including partition, storage procedure, optimizing query sentences, etc. It effectively improved the access and extract efficiency of verification data, and provided references for the same and similar application requirements. |
