在WEB 應用的背景下，針對系統可擴展性不強、開發難度大、系統耦合性等方面的不足，提出了一種基于數據島技術與AJAX、JavaScript 技術相結合進行WEB 系統應用的
方法，通過對系統的設計實現，得出利用上述技術實施系統的可行性，最終得到簡單、易行、層次分明、開發周期較短的WEB 系統。

Abstract: Under the web application background, the system scalability is not
strong, the development is great difficulty and coupled. So such as the shortage,
we proposed a new technology based on data Island and AJAX, JavaScript technology
combined with the application system WEB method. According to the design and
implementation of the system, that using the technical implementation, so the
feasibility of eventually is simple, easy, structured, and can achieve shorter WEB
system development cycle.
