摘要
沉降监测数据库是安全监测数据存储与管理的基础,应确保数据库具有可靠性和扩展性,本文以城市地面沉降监测数据处理系统为例,结合数据库的知识,详细阐述了系统数据库设计思路与过程,实现了数据管理的有效、简便、科学。系统数据库主要含有3个部分,包括原始观测数据库、网平差数据库和沉降变形数据库。通过这3个部分数据库,系统能进行原始水准数据处理、平差、变形分析及沉降数据的处理。
As database of subsidence monitoring is the foundation of data storage and management in safety monitoring , we must en-sure that the database has the reliability and scalability .Taking the urban land subsidence monitoring data processing system for exam -ple, combined with knowledge of database , this paper elaborates the design ideas and process of the database and implements effec -tive, simple, scientific data management .The database contains mainly three parts：the database of original observation , the database of network adjustment , the database of settlement deformation .So the system can implement functions such as raw level data process-ing, adjustment, deformation analysis and settlement data processing with three databases .
