The function of query and statistics of data is always the basis of production management and decisionmaking businesses. According to the results of information construction and applications for many years

the mode

function and performance of data query and statistics still do not satisfy the actual needs. A component for data query and statistics based on supervisory graph software is proposed and developed. Through the design of data path architecture

the optimization of query and statistics mechanism

the developed component has achieved personalized management

lightweight analysis and flexible query of real-time data. The query and statistic component and data link mode developed in this study have been tested and applied in practice. The results show that the function of data query and statistics achieves loose coupling with database. The component can support both the operation modes of C/S and B/S

and provide unified query and statistics of data through supervisory graph from multi-data sources and multi-level organizations. The efficiency of data query and trend query reaches or approaches the level of database native management tools

and is better than that of conventional supervisory information system(SIS) websites. The integration mechanism of data components based on graph with SIS data query and report system is proposed

which helps to reduce the repetitive cost of data use.
