Based On The GWT Framework Of The Human Resources Information Management System Design And Development

With the development of computer networks and lightweight database in a lot of use of many small and medium enterprises, business needs a lot of human resources information management and query needs, requirements system faster interactive capabilities. When the user’s query is not fixed demand often transform fixed user interface can only adapt to the fixed demand, this lack of interaction of human resources information management system, and obviously can not meet the needs of users. Web applications now used interfaces that were not generated through templates on a web server but with JavaScript in the client browser. Using Ajax techniques to build web applications caused an huge change in web application architecture. JavaScript asynchronously send data requests to the server, and update web pages will not lead to refresh. The previously smooth Web applications, more and more like a fully integrated desktop applications, the operation does not appear to pause or integrity of the interface refresh.Google Web Toolkit (GWT) is a Java-based application framework for Ajax. By this framework, Java developers do not have to learn JavaScript, also can be able to create Ajax applications easily. How to build based on the GWT human resources information management system is the focus of this discussion content.This article discusses the technology is based on the the GWT framework of systems research and realization. Presentation layer using a the SmartGWT framework for the realization. The purpose of this system is to make the user through a small number of database configuration can connect and use the flexible query and information management system and database. Due to the use of design patterns GWT rich client/server-based framework, the client automatically download scripts and static files from the server once. Use GWT’s AJAX-based front-end technology can greatly alleviate the pressure of the server. This system uses the Java programming language (GWT library) write AJAX front, then GWT cross compiler optimized JavaScript JavaScript can run on all major browsers. Human resources information management system is stressed on the client system, in order to focus on the client’s design, extensive use of reusable Control and user interface module, greatly reducing the amount of code in order to achieve a flexible information management capabilities.
