摘　　要：介绍基于PDA(Personal Digital Assistant)的上海港港政监督管理信息系统的功能模块和关键技术。该系统包括作为后台支持的局域网子系统和PDA子系统,以PDA子系统为例介绍Web Services在智能设备中向服务器端数据库SQL Server2005传输和下载数据的方法和优势,以局域网子系统为例介绍ASP.NETAjax(Asynchronous JavaScript and XML)技术在实现Web页面的数据显示和编辑修改方面的关键技术和优势。使用Ajax技术不仅可以降低服务器负荷而且能解决Web页面整页刷新带来的白屏问题,使用Web Services技术则可以在PDA上更加安全有效地向服务器传输数据。This paper presents main function modules and key technologies of the Information System of Supervision and Management for Harbour Governance based on PDA at Shanghai Port. The System consists of two parts including PDA subsystem and LAN subsystem which is used for background support. PDA subsystem is taken as the instance to have introduced the advantages and methods of Web Services in transferring and downloading data to database SQL Server2005 at server in intelligent devices, and ASP. NET Ajax （ Asynchronous JavaScript and XML） technology is introduced its key techniques and advantages in realizing data display of Web pages and editing modification with the LAN subsystem as an example. Using Ajax can decrease the burden of Server and resolve white screen problem incurred from webpage refreshing as well, and by utilizing Web Services technique it will be more safe and efficient to transfer data to Servers on PDA.
