The model is composed of the system development cycle and the system maintenance cycle 此模式包含了系统发展周期及系统维修周期。
If use it , the information system development cycle can be shortened , and information system can be recycled 组件式开发可以缩短信息系统的开发周期,可以实现信息系统的重复利用。
Student teams will work a case study through the full information system development cycle using project management and modelling tools 学生以小组形式使用项目管理和模型工具完成一个完整信息系统的开发。
The measure should be meaningful to the end - user or purchaser of the system , and could be easily extracted early on in the system development cycle 量度的资料须对终端用户或系统购买者具有意义,并可以在系统发展周期的初期轻易计算出来。
The system development cycle covers a number of phases starting from project request , feasibility study , systems analysis and design , implementation and post implementation review 系统发展周期由数个阶段所组成,包括最初之计划要求,其后之可行性研究,系统分析及设计,推行,及最后之计划推行后的覆检。
