摘　　要：海洋传感观测服务能够实现多个海洋观测系统间的数据共享与集成,支持大范围、多学科的海洋科学研究。在软件开发过程中,由于不同观测系统的数据库异构互异,导致传感器观测服务软件难以复用,开发效率低。本文针对数据库结构的相似性进行分析,提出海洋传感观测服务的柔性开发模型,设计可适配于异构数据库的服务构件。该构件通过配置观测数据在具体数据库的存储结构,实现了数据库结构向服务模式定义的映射;服务构件根据配置信息生成数据库查询语句,实现观测数据的自动提取,避免了数据库异构导致的重复开发的问题。通过将服务构件应用在实际开发中,验证了该模型的有效性与可行性。Ocean sensor observation service enables data sharing and integration among multiple ocean ou- serving systems and supports multidisciplinary science research in large scale. In software development process, sensor observation service software is difficult to use and the development efficiency is low due to database structure is heterogeneous between different observing systems. This paper analyzes similarities of different database structures, proposes flexible development model for ocean sensor observation service and designs service component that can adapt to heterogeneous databases. The service component realizes mapping from database structure to service schema by configuring actual database storage structure; the component generates database query according to configuration information and implements automatic ex- traction of observation data, avoiding repetitive developments caused by database heterogeneity. The mod- el is proved to be feasible and efficient through applying it to practical developments.
