【正文】 th a foreground program, and then users can store and query data through the browser or client. This project is to design and implement a WEB database based ARM. Entering data through the soft keyboard, users can connect with the server and perform query data. PC acts as a server and FriendlyARM Tiny6410 development board with external touch screen as a client. The software part of the system consists of server and client ponents. It uses Qt graphical user interface to develop and SQLite database to store data. Then we can connect to database and operate it in Qt. The client runs the Linux operating system. A driver is transplanted to control and use of the wireless work card to achieve wireless work connection. Client interface mainly includes user login screen and query screen. According to the embedded systems developing process, this thesis consider Qt programming, SQLite databases designing and Embedded Linux operating settings. Taking the student information system for example, users operate on the ARM terminal and gain the student information that stored in a remote server. This information is transferred to the ARM terminal via work. The information can be further applied to other systems and lay the foundation for more plex embedded system designs.
