摘要 在综合现有的信息系统开发方法的基础上,提出一种新的信息系统工程开发方法──模块抽象机制法;本文详述依赖于数据库的支持模块抽象机制法的开发工具DISGTS(DatabasebasedInformationSystemGeneratedToolSystem)的设计与实现。 In our development work, we foresee the need in China for a high level database application processor [8]. In this paper, we present such a processor, which we call DISGTS(Database based information System Generated Tool System).Fig. 4 is a schematic diagram of DISGTS, which is based on the concept of modular abstraction, which, in turn, comes into being after our careful study of the very recent object-oriented concept [3] and two known engineering development methods: (1) the wellknown life-cycle method: (2) rapid prototyping technique [1].Modular abstraction is done differently for different objects: (1) abstraction based onrelation database theory, when object is clearly related to databade; (2) abstraction based onexperience when object is only remotely related to database. DISGTS is developed in Microsoft Windows 3. 1 wicli Foxpro on PC386 or 486. Preliminary success in using DISGTSindicates that it is promising.
