中国数字测震台网直接服务于我国的防震减灾事业。在“十五”中国数字地震观测网络等项目的支持下，原来的模拟记录系统将逐步被取代，这是地震观测工作中的一大飞跃。它使我们有可能更快地进行大震速报，更方便地从地震记录中获取更多、更真实的来自地球内部介质和震源过程的信息，从而进行更深入的地震科学研究。为了实现测震观测数据的共享和服务，可以通过Oracle数据库来存储数据，并开发一个应用系统来管理数据。 本论文介绍了测震数据库在Oracle平台上的设计和建立过程，并利用PowerBuilder语言来开发测震数据管理系统。 （1）测震数据库的建立。通过对Oracle数据库体系结构的分析，结合数据入库和数据使用两个环节的应用特点，参照中国地震局的有关标准，来设计数据库的库结构、表结构。根据数据库的设计，来完成测震数据库的建立工作。 （2）测震数据管理系统的开发。PowerBuilder（简称PB）是一种面向对象程序设计的数据库开发工具。运用其开发一个对测震观测数据的管理系统，实现数据的入库、管理、导出、查询、分析等业务，方便用户管理测震数据库。 测震数据管理系统开发完成后，可以实现对测震观测数据实行数据库管理，并能进行快速地查询访问。它使测震观测数据格式得到了规范与统一，实现了对数据的统一管理，方便了用户对数据的使用和共享，提高了工作效率，可以很好地为地震监测预报提供服务。

China digital seismic network can service directly to the preventing earthquakes and reducing disaster. Under the support of fifteenth China digital seismic observation network project, the original analog recording system will gradually be replaced, this is the big leap of the earthquake observation. It has made it possible for us to report earthquake faster. We can get more and real earth medium and seismic source process information from seismic records more easily. In order to realize the sharing and services of seismic observation data, we can build a database which based on Oracle to store data, and develop an application system to manage data. This paper introduces the designing and establishment of auspice database, as well as how to develop the auspice data management system by PowerBuilder. The construction of seismic database. Through the analysis on the Oracle architecture, combined with the application characteristics of data warehousing and using, in reference to the relevant standards of China seismological bureau, to design the database structure and table structure. According to design of database, we complete the establishment work of seismic database. The development of seismic data management system. The programming language PowerBuilder(PB) is a of object oriented programmer for database．PB has been applied to build a database management system, which can realize the function of data warehousing, management, export, query and analysis, also can provide convenience for user to manage seismic database. After accomplishing the development work, we can use seismic data management system to manage the data by database, and reach quick query for data accessing. The system can make the data format to achieve standard and unity, come true uniform data management. The seismic data management system is convenient and efficient for user, can offer good help for the work of earthquake monitoring and prediction.
