【Abstract】 This paper introduces a Web Information System automatic generation Environment(WISE) based on user-driven reusable templates,and proposes a new agile components reuse and dynamic schema modification (DSM) strategy on visual template models to meet various needs.Based on the concept of reference in Object-Rational Database,by using the idea of inheritance,the strategy defines the reference relations among templates. Not only carries out the reuse of interface elements and operations,the strategy also frees the user to overlay or to modify the elements of referenced templates.During the process of dynamic schema modification,such modification spreads abroad to all templates which refer to the template,it guarantees the system integrity and semantic consistency, brings down the complication of software development and maintenance.更多还原
