植物信息系统的设计与应用

Plant Information System Design and Application

本文将分布式数据库技术与网络技术相结合,并将分布式技术引入植物标本数据库网络查询系统,采用WebSer-vice技术及异步调用方法实现分布式数据检索,不仅能方便internet网络用户查询植物标本数据,而且可提高标本数据的利用率,有利于实现资源共享;运用Internet网络技术、ASP技术以及数据库技术将植物标本馆进行数字化,使标本及其各种属性得到永久性保存;为了弥补集中式数据库系统在覆盖率、更新率、访问权限控制、专业性及网络负载等方面存在的缺陷,本文设计并实现了一个可扩展性强的分布式植物标本信息系统。

This paper will be distributed database technology and network technology, and the introduction of plant specimens distributed database technology for network systems, using Web Service technology and asynchronous method called distributed data retrieval, the network will not only facilitate intemet users for plant specimens data, And specimens can improve the utilization of data, be conducive to realizing the sharing of resources; The use of Intemet technology, ASP and database technology to digital technology will Herbarium, specimens and its various attributes to be a permanent preservation; order to make up a centralized database system in the coverage, renewal rate, access control, professionalism and network load In areas such as the shortcomings, This paper designed and implemented a scalable, distributed information system of plant specimens.
