基于模型驱动的海洋环境数据平台研究与应用

摘要

On the basis of the Model Driven Development (MDD) , a marine environment data platform is proposed, and its key points both of the data model design and functions design are discussed, and a prototype system which based on the Web Services is also implemented. Taking the data object model as its core, loosely coupling users' business logics with the marine environment data, those problems, such as low efficiency, lack of expansibility and universality, which usually exist in the traditional database design method for the marine environment data storage and management with the characteristics of dynamical changing on spatio-temporal attributes, can be solved by this data platform. By applying this data platform in the management and application for the marine environment data, and the management efficiency and sharing service can be improved.%设计了基于模型驱动架构的海洋环境数据平台，论述了其数据模型设计和功能设计，开发了基于Web Services平台原型系统。该平台以数据对象模型为核心，实现了海洋环境数据与用户业务逻辑的松散耦合，解决了传统数据库设计模式在面对具有时空动态变化特性的海洋环境数据存储与管理时出现的效率低、扩展性和通用性不足等问题，提高了海洋数据管理效率和共享服务能力。
