Embedded systems in the current increasing demand for social applications , embedded technology development is also increasing rapidly. With the increased demand and embedded systems performance enhancements , the Web application technology integration into embedded systems to be present and even hot research topic in the next few years . Therefore, in the Embedded System Web applications connect to the Internet and use the technology has a very important research and application value. This paper describes the implementation of the key technologies of embedded Web applications and SQlite database , built with ARM9 processor and embedded Linux operating system as the core development platform , studied and implemented an embedded Web server. According to the embedded systems there is a small storage space and processing power of the weak features , embedded Web server for the restrictions imposed on the problem , propose an embedded thin Web server architecture. With the use of Ajax, the original on the server side user input validation, processing and so on to the relative wealth of resources on the client PC , thus reducing part of the original on the server needs to handle the work, to reduce its load ; but it will bring the Web page code is too large, the page is not easy to update and maintain. This topic will be taken using Ajax handling mechanism embedded in HTML pages separate Java Script script , reducing the amount of code a Web page , Web pages to produce a light favorable for the maintenance and updates. According to the SQLite programming highlights and features on SQLit analysis and research , to achieve the embedded Web server embedded in an SQLite. Combined with CGI to complete its expansion capabilities to achieve the client and the embedded Web server dynamic interaction , and successfully applied in the embedded Web attendance systems. Embedded Web server application in thin attendance system, well done embedded attendance system connected to the Internet the functional requirements , to meet the system administrators remote access to the system and maintenance requirements .
