Abstract: Tianjin public emergency early warning information release system（TJEWRS）is a very important comprehensive information release system in Tianjin,it is the total export of early warning information release authorized by governments at all levels,and forms a four-level interconnected early warning information release system with the national early warning release system（NEWRS）. Baodi District public emergency early warning information release platform（BDEWRP）,as the third level of the early warning release system,plays an important role in disaster prevention and mitigation and emergency management in the region under its jurisdiction. However,due to the early construction,the data statistics function is relatively simple,and with the continuous development of early warning release business,it can no longer meet the current data statistics needs. In order to facilitate the statistics of various early warning information release data of BDEWRP,BDEWRP query statistics tool was designed and developed based on TJEWRS database,so as to optimize business data statistics and reduce the workload of business personnel. This paper introduces the design purpose,significance,design idea,process and main query statistics algorithm of BDEWRP query statistics tool.
