增量统计方法在二代身份证系统中的应用

Application of Incremental Statistic Method to Second Generation ID Card System

报表统计在二代身份证系统中非常重要,而且要求以天为单位按行政区划统计。当数据量比较小时,可以实时统计,但是当数据量比较大时,实践表明如果采用常规的统计方法,性能较差。因此,针对这种情况,提出了一种基于ORACLE的新统计方法—增量统计法,提高系统性能,来满足省、地市、区县、派出所各级公安机关工作人员的统计需求。

Report statistics is very important in the second generation ID card system,and more it’s statistics according administrative per day.When the amount is small,the system can be real-time statistic,but when exists a large amount of data,practice shows that if use usual statistic method the system is poor performance.Therefore in this case the paper proposes a new statistic method base on oracle–incremental statistics to improve system performance and to meet the statistical requirements for all level public security staff such as provincial,city,district police station.
