Web Service技术在古树名木电子导游系统开发中的应用

Application of Webservice Technology in the Development of Electronic Guide System for Ancient Trees and Famous Trees

针对各省市古树名木数据库资源未广泛使用与不能共享问题,且在手机平台下多任务访问古树名木信息性能不高,易出现未响应错误的问题,提出一种基于Web Service和Android结构的古树名木电子导游系统实现方法。系统框架由安卓手机应用平台、SQL Server和基于Web Service的数据库服务器三部分组成。手机应用平台在访问Web Service服务器时,应用线程池技术,从而避免手机平台出现应用无响应错误。从而实现古树名木数据库开发利用和共享,系统的古树名木数据库中心采用Web Service与触发器技术结合方法,实现分布式异构古树名木数据库的同步操作。通过测试验证了系统的有效性。

According to the various provinces and cities of ancient and famous trees database resource sharing problem and not widely being used, and in the mobile phone platform under multi task access ovts performance information is not high, not prone to error response problems, the paper puts forward a Web Service tour system and Android structure of ancient wooden electronic guide implementation method based on the system fl＇amework by Android. Mobile phone application platform, SQL Server and Web Service based on the database server is composed of three parts. In the mobile phone application platform to access the Web Service server, using the thread pool technology, so as to avoid the mobile phone platform application not responding errors. In order to achieve the development and uti- lization of ancient and famous wood database and sharing system of ancient and famous trees using Web and Service database center the trigger technique combined with the method to realize synchronous operation of distributed heterogeneous ovts database. The validity- of this system is verified through the test.
