Design of Massive Information Index System for Power Grid Data Mart Considering the Hash Index

针对当前电网数据集市海量信息索引未考虑排序处理数据信息,导致系统检索效率和查全率低,稳定性差的问题,提出考虑哈希索引的电网数据集市海量信息索引系统设计方法。该系统聚类融合处理数据信息,根据关联规则挖掘结果提取与检索数据,结合哈希算法排序融合电网数据信息。该系统采用B/S三层体系,将其分为表示层、功能层和数据层,从而实现了系统的功能模块的设计,完成电网数据集市海量信息索引系统设计。实验结果表明,该系统设计方法的检索效率和查全率更高,稳定性更好。

In order to solve the problem of low retrieval efficiency and poor stability of the current power grid data mart massive information index system, which does not consider sorting data information, a design method of power grid data mart massive information index system considering the Hash index is proposed. The system clusters data information of fusion process, extracts and retrieves data according to results obtained by association rules mining, combines with the Hash algorithm sorting fusion power grid data information. The system adopts B/S three-tier system, i.e., presentation layer, function layer and data layer, thus realizes the design of system function modules, completes the power grid data mart mass information index system design. The experimental results show that the system design method has higher retrieval efficiency and recall, and better stability.
