基于EPICENTRE的海洋钻探数据库构建方法研究

摘要

随着海洋在经济发展中的地位日益突出,海洋地质调查越来越重要,如何合理地管理使用海洋地质调查数据成为研究热点.文中以海洋钻探为例,采用面向对象的技术方法,提出了基于EPICENTRE数据模型的海洋钻探数据库构建方法,实现了海洋钻探业务与EPICENTRE数据模型的关联.该方法得到的海洋钻探数据库是面向业务的,与传统的关系数据库相比具有良好的可扩展性,稳定性以及关联性等优点.文中重点对业务模型与逻辑模型的关联技术进行了介绍.%As the marine in the economic development is becoming increasingly conspicuous, the status of marine geology survey is more and more important, how to use proper management of the marine geology survey data becomes hotspot. In this paper .took the marine drilling as an example,by using object oriented technology method,put forward the marine drilling database building method based on the EPICENTRE data model .realized the association of the EPICENTRE data model and the business of marine drilling. This marine drilling database is facing with the business,compared with the traditional relational database has good expansibility,stability and relevance,etc. It focuses on the business model and the logical model associated technology.
