摘　　要：海洋数据可视化查询系统对提高海洋数据查询效率、改善数据展示友好性具有重要意义。针对海洋数据库数据异构问题,研究设计了可视化信息数据库,为数据可视化业务层提供统一的数据层接口。利用组件技术设计实现海洋数据转换、数据查询及数据可视化功能,解决一般海洋数据管理系统仅能满足特定需求的局限性,提高系统的可扩展性及模块的可移植性。以渤海海区数据作为数据源开发原型系统验证了该系统的实用性。This work implements a visualization system for the existing heterogeneous marine data.The system is divided into three parts： the data layer,the logic layer and the application layer.A visualization information database is designed to solve the heterogeneity problem,providing a unified access to the data layer for the logic layer.Marine data transformation,data query and data visualization modules are developed using component technology in order to eliminate the limitations that the traditional systems only works well under certain circumstances.Components based modules highly improve the extensibility and reusability of the system.The capabilities of the visualization system are illustrated by specific applications using data from the database in the selected Bohai sea area.It proves that the visualization system is of good quality and can be used in the developments of most marine data management systems.
