摘要
消灭“软件遗产工程”,实现软件的“自由动态修改维护”,是软件工程学面临的一大难题,至今尚未彻底解决。文中提出一种新的应用程序的构建模型—“AOV网模型”(modelofActivityOnVertexnetwork),即用AOV网描述应用程序的拓扑结构,用脚本语言构造AOV描述文件,利用事件驱动机制,通过周游AOV网,控制调度程序的运行。使程序的功能流程完全由可编辑的AOV描述文件确定,实现了软件的完全、自由意义上动态修改、维护特性。解决了可执行软件像铁板一块,不可改变和重用等弊端。作为构建模型的应用,给出了“语音服务系统”的设计与实现。
It is a tough issue that cutting the throat of ＂software inheritance project＂ and realization ＂free and dynamic revising and maintenance＂ of software.And so far the issue hasn＇t been resolved thoroughly.In this paper a new application model-＂AOV network model （Model of Activity On Vertex network）＂ is put forward.The content of AOV network model are topology framework of application described by AOV,constructing AOV description file by script language,making use of event-driven mechanism,via circuiting AOV network,controlling the running of scheduler.This makes the flow of the program confirmed by editable AOV describing file and free,thus dynamic revising and maintenance＂ of software is realized.As the application of constructing model,the design and realization of ＂Voice Service System＂ is advanced.
