SCFE: A kind of Smart Client Flow Engine based on Ajax

In order to solve the lack of intelligence and server overload problem that exits in the traditional Ajax engine, a new Ajax engine based on the browser caching mechanism named SCFE (Smart Client Flow Engine) is proposed. It separates business logic layer from data access layer, and transfers business logic layer and the relevant data to the client catch to implement. The theory and the practice prove that SCFE can not only reduce the frequency of accessing server effectively and solve the server overload problem, but also make the web applications more intelligent.
