面向对象技术在多媒体CAI开发系统中的应用

多媒体ＣＡＩ的开发和应用迫切需要一个专用的高性能的创作平台，以便能支持多媒体课件的快速制作，支持多媒体资源的超媒体形式的动态链接以及事件驱动的演播方式。这就需要构造一个合理的多媒体ＣＡＩ数据模型，以及采用与之相应在的开发方法。传统的数据模型和ＣＡＩ系统设计思想在解决这些问题上有许多局限，而面向对象技术则能更好地完成上述要求。本文以作者用面向对象技术开发的一个多媒体ＣＡＩ软件创作平台（称作Ａｎａｌｙ

Object-oriented Techology in Multimedia CAI Developing System

The development and application of multimedia CAI is in an urgent need of a specified and highly functioned authoring environment, which can be in support of the multiplication of multimedia courseware and hypermedia dynamic link of multimedia resources as well as the rendering of event - driven. It requires to make an appropriate data model of multimedia CAI employed a suitable way of development. However, there are some limitations on traditional data model and design performance of CAI system, while object - oriented technology is able to fulfill these requirements. In this article, the author makes introductions about the structure and data models of object - oriented multimedia CAI system and oo development method wielding multimedia CAI system, which are based on authoring environment of oo multimedia CAI software (That is, Analyzing & Guiding Studio, A&G Studio). Combining the design and application of A&G Studio, we offer a brief sketch of object - oriented data modeling of multimedia CAI, sturcture design of software system and some practical research and application of developing multimedia software.
