Analysis and Design of Software Framework Based on Three-tier Architecture

Component-based software development technology is the main means of software reuse.How to achieve the interaction and connection among components is the foundation of using the component technology.This paper presents a reusable software framework based on the typical three-tier architecture.The purpose is to achieve the link among components and improve the software developmental efficiency.Within this framework,the standards of interface,the communication rules and the hot spots of the framework are defined,increasing the extension of the framework.Within this framework,developers can integrate the proper components to the framework,In addition,the framework provides the standard of the interface for the components designer.
