问题 Regardless of how well designed, constructed, and tested a system or application may be, errors or bugs will inevitably occur. Once a system has been(  ),it enters operations and support.Systems support is the ongoing technical support for user, as well as the maintenance required to fix any errors, omissions,or new requirements that may arise. Before an information system can be(  ), it must be in operation. System operation is the day-to-day, week-to-week, month-to-month, and year-t-year(  )of an information system's business processes and application programs.Unlike systems analysis, design, and implementation, systems support cannot sensibly be(  )into actual phases that a support project must perform.

答案 BACDA

解析 无论一个系统或应用程序的设计、构造和测试有多好,错误或者漏洞都将不可避免地发生。一旦系统被(实施),它就进入了操作和支持阶段。
系统支持是对用户的持续技术支持,以及修复可能出现的任何错误、遗漏或新需求所需的维护。在(支持)信息系统之前,它一定已经在运行状态了。系统运行就是信息系统的业务流程和应用程序日复一日、周复一周、月复一月、年复一年的(执行情况)。
与系统分析、设计和实现不同,系统支持不能合理地(划分)为支持项目必须执行的实际阶段。相反,系统支持包括四个正在进行的活动,即程序维护、系统恢复、技术支持和系统增强。每个活动是一种支持项目,它是由所实现系统遇到的特定问题、事件或机会(触发)。
