面向地震层析成像数据库的设计方法

Approach to Designing seismic Database on Tomographic Studies

本文概述了面向对象数据库的特点，及与传统数据库的区别．结合面向地震层析成像数据库的设计，具体描述了定义地震事件对象、地震震相和地震台站对象，确定属性、操作和类的方法．最后，讨论了用Ｆｏｘｐｒｏ２．５ｆｏｒＷｉｎｄｏｗｓ实现面向地震层析成像数据库的一些特征．

In this paper, we review the relational and current object-oriented database design methodology and attempt to show the difference between them, and that describe the approach to designing the seismic database, including to identny the object of earthquake, seismic phase and station, as well as their attributes, operation on the attributes f and classes.Finally we present the features of tomography oriented on Anplementing seismic database by using Foxpro 2. 5 for Windows.
