THE DESIGN AND IMPLEMENTATION OF CDBAG-4GL-AN INTERGA-TED AUTOMATIC GENERATORS FOR RAPID DEVELOPMENT OF MIS

本文论述了“一体化MIS快速开发自动生成器系统CDBAG—4GL”的设计思想、方法和实现技术等,并对其系统构成设计、用户接口设计以及系统特点作了简要介绍,“CD-BAG—4GL”已商品化,它支持全新的MIS开发新方法——“快速原型法”;它采用高度非过程化的第四代语言作为友好用户接口;它根据用户需求定义即可快速自动地生成相应的具体MIS;它为应用开发人员和最终用户提供一个综合的全面的一体化的快速开发工具和环境,是成数量级的提高MIS开发效率、质量、缩短开发周期、降低开发成本的有效途径,是促进MIS开发走向标准化、工程化和自动化的有效方法。

This paper expounds the design and implementation of CDBAG-4GL, i. e. an intergated automatic generators for quickly development of MIS. The architecture design, user interface and characteristics of the system are also briefly described. CDBAG-4GL, which has been commercialized, supports an original method of developing MIS, i.e. Rapid Prototyping. It uses a highly nonprocedural 4th Generation Language(4GL) as the user-friendly interface. According to the application: Requirements, CDBAG-4GL can generate the corresponding specific MIS automatically and quickly. As an integrated general quickly developing tool and environment, CDBAG-4GL can greatly improve the efficiency and quality of the development of MIS, as well as reduce the cycle and costs of the develepment. In short, CDBAG-4GL provides and efficient way to standardize, engineerize and automatize the development of MIS.
