Application of Mobile Database in Flood Prevention System on PDA Ran Chongshan Chi Jingyuan Abstract: In order to satisfy the unique demand in flood prevention，this paper designs an implement a flood prevention information management system on PDA based on embedded mobile database. The most important part of this system is designing and implementing a middle-level software component based on SQL Server 2000 and SQL Server CE embedded mobile DBMS, using many kinds of programming technique (including embedded system programming, mobile database technology, mobile communication technology, and so on ).This component realizes the Push-Style information service based on SQL Server CE, expanding the function of this embedded mobile database management system
