摘要
在信息技术飞速发展的当代,如何对高精度、多维度、多源异构的海洋环境数据进行有序管理和高效应用是一项重点和难点。通过采用特定领域建模(DSM)技术,设计面向海洋领域的环境数据管理模型,论述其数据对象抽象和元模型构建过程,并开发了应用系统实例,验证了模型的有效性,在实现海洋环境数据与具体业务逻辑的松散耦合的基础上,解决了基于数据库的传统设计模式在管理多源、异构、多模态的海洋环境数据时遇到的效率低下、灵活性差和扩展性不足等问题,提高了海洋环境数据的管理效率和服务能力。
Along with the rapid development of information technology, orderly management and efficient application is an important and challenging technique for marine environmental data, which have high-precision,multi-dimensional and multi-source heterogeneous features. This paper puts forward an ocean-oriented environmental data management model based on DSM, expounds abstraction of data objects and meta-model＇s establishment process concerning this model, and then illustrates an application instance to prove its validity. The proposed model integrates marine environmental data and concrete business logic in a loosely coupled manner,and therefore solves the problems of low efficiency, less flexibility and insufficient extensibility in managing multi-source, heterogeneous and multi-mode marine environmental data based on traditional database design,and ultimately improves the management efficiency and service capacity of marine environmental data.
