PIP:国际项目管理信息系统发展 的新阶段 国外项目管理软件经过了3个不同发展时代,形成了结构与功能完全不同的3代信息管理系统。 第一代项目管理软件产品是20世纪60-70年代基于大型计算机的集中式项目管理信息系统。这个时期的项目信息系统在结构上、数据的处理计算完全在主机上完成,因而容易把项目实施过程中的数据集中起来,形成统一的项 PIP: A New Phase in the Development of International Project Management Information System Foreign project management software has undergone three different development stages and has formed a three-generation information management system with a completely different structure and function. The first generation of project management software products was a large-scale computer-based centralized project management information system from the 1960s to the 1970s. During this period, the project information system is structurally constructed and data processing and calculation are completely completed on the host computer, so it is easy to centralize the data during the project implementation to form a unified item
