摘要：分析林业信息系统中信息孤岛形成的原因,提出基于服务的数字林业数据管理平台体系结构。服务层通过Web服务技术屏蔽了操作系统和数据库系统的异构性,公用数据元目录机制消解了系统在语义层的异构性,汇聚层融合子节点元数据并统一访问接口,从而在全林业行业范围内实现分布异构数据的统一管理和访问。平台保持系统间的松耦合性,克服异构数据转换的关键性难题,向用户提供简单一致的数据访问方式,符合当前林业管理体制,具有广阔的应用前景。
The reasons for the formation of isolated island in forestry information system were analyzed,and a service-oriented architecture of digital forestry data management platform was proposed in this paper. The service layer shielded the heterogeneity of operation system and database system by means of Web service techniques,the common data element directory eliminated the system heterogeneity at semantic level,and the aggregation layer integrated the metadata of sub node and unified the access interface,which realized the unified management and access of distributed heterogeneous data in the whole industry of forestry. The platform kept the loose coupling among the systems,and overcame the key difficult problems in the exchange of heterogeneous data. The proposed platform will provide a data access method for asers in a simple and consistent manner,which conforms to the current forestry management system and has a broad prospects in application.
