基于PDA的应用系统框架的设计和实现

Design and Implementation of Application System frame Based on PDA

随着信息技术的蓬勃发展,处理信息的方式也变得多样化。特别是随着PDA的应用越来越广泛,基于嵌入式系统的分布式数据库的信息处理系统以一种崭新的形式得以实现。在WinCE的操作系统下,使用SQLServerCE数据库,构成PDA中独立的信息系统,采用数据同步机制,与服务器的数据库进行数据交换,从而保持数据的完整性。本文提出了这种基于PDA的信息系统框架,并在此基础上将该框架成功地应用到水路征稽系统上。

Along with the booming development of information technology, the way dealing with information becomes various. Especially according with the application of PDA become more and more broad, the information processing system based on distributed database of embedded system can be realized with a new form.. Under WinCE OS, using SQL Server CE DBMS, an independent PDA information system can be composed. Adopting data synchronism, the database on PDA exchanges data with the one on server to keep the data integrality. This paper brought out such an information system frame on PDA platform, and applied this frame on Waterway toll system successfully.
