面向业务的海洋地质数据服务平台构建方法

Method for construction of business- oriented marine geology data service platform

随着海洋地质调查程度的日益深入,海洋地质数据越来越多,现有海洋地质数据服务体系难以满足应用需求。通过分析现有海洋地质数据的应用现状,提出了"三层"体系结构的海洋地质数据服务平台设计方案,采用面向业务的方法设计了基于业务的统一逻辑模型,运用WCF技术和NHibernate技术初步实现了海洋地质数据服务平台,实现了对分布式异构海洋地质数据库的集成访问和基于业务模型的数据查询。与传统数据查询方法相比,用户只需选择自己的业务需求,设定约束条件即可获取数据,极大地方便了用户对海洋地质数据的应用需求。

With the deepening of the marine geological survey, marine geological data have been increasingly accumulated, but the marine geological data service system can not meet the application requirements. Through analyzing the status of the application of existing marine geological data, the authors presented “Three -layer”architecture of the marine geological data service platform design approach, designed the unified logical model based on business using object-oriented thought, implemented marine geological data services platform using WCF and NHibernate technologies, realized integrated access to heterogeneously distributed marine geology database, and achieved data query based on business models. Compared with the operation of the traditional method for data query, users can simply choose business needs, and obtain the data after setting up constraints, thus greatly facilitating the user’ s application demand for marine geological data.
