MANAGEMENT AND SERVICE OF DISTRIBUTED MULTI SOURCE HETEROGENEOUS MARINE GEOLOGICAL DATA

摘要:
多部门合作产生的海洋地质数据有着分布式、多源、异构的特点，在建构现实的海洋地质数据库系统过程中，通过解析海洋地质数据特征，在不改变原始数据的存储和管理方式下，提出一种基于统一数据模型的异构数据集成模式和基于WCF的数据与应用发布方式，从而实现多源异构数据统一、透明的集成访问，构造数据服务的基础。
Abstract:Marine geology data produced by multiple channels are usually distributed, multi-sourced and heterogeneous. In the process of constructing a realistic marine geological database system, we noticed the characteristics of marine geological data, and then proposed a heterogeneous data integration mode based on a unified data model and the way of data and application service based on WCF. The unified logical data model is mainly made with reference to the POSC model which was generally used in the field of oil and gas. In the WCF service architecture, data and applications are packaged into class objects and transfered by object serialization and deserialization. This form of system design has the advantages of on unchanged storage and management mode of original data.
