基于UML的计算机课程线上教学系统设计

Design of Online Teaching System for Computer Courses Based on UML

由于传统系统在实际应用中对于教学资源更新效率比较低,因此本文提出基于统一建模语言(Unified Modeling Language,UML)的计算机课程线上教学系统设计研究。系统硬件设计了教学数据存储器、服务器和数据转换器3个硬件设备;软件方面通过数据干扰去除、传输信道分配以及通信功率分配,构成数据传输机制。此外,利用UML建立系统数据库模型,存储计算机课程教学资源。实验结果证明,设计系统教学资源更新效率高于传统系统,更适用于计算机课程线上教学应用。

Because the traditional system has low efficiency in updating teaching resources in practical application, this paper proposes the design and research of computer course online teaching system based on Unified Modeling Language(UML). The hardware of the system includes three hardware devices: teaching data memory, server and data converter;In terms of software, the data transmission mechanism is composed of data interference removal, transmission channel allocation and communication power allocation. In addition, the system database model is established by using UML to store computer course teaching resources. The experimental results show that the renewal efficiency of teaching resources of the designed system is higher than that of the traditional system, and it is more suitable for the online teaching application of computer courses.
