问题 单项选择题

根据以下信息,回答第18题至第22题。

一家历史悠久的保险公司拥有4500名职工和150个销售办事处。10年来,该公司一直使用一个只有低速终端链接的大型主机系统,为区域办事处和公司分析人员提供支持。该公司推销个人和团体的人寿保险以及投资产品。由于数据转换费用高且传送速度慢,所以并非所有有需求的人都可以进入主机系统。

考虑到要在今后的3年内将公司的市场份额增加15%,管理人员认为缺乏响应系统是一个非常棘手的问题。他们认为,如果公司对于保险持有者和新客户的需求反应更迅速,则成长目标是可以实现的。

每个人都同意用户需要以更快的速度获取保险信息,但是就如何实现这一点却无法达成一致意见。关于提高访问速度和支持新的应用,最受欢迎的方法有两个。一是在升级后的主机上整合现有的独立数据库,二是在基于局域网(LAN)的个人计算机上安装通信软件使数据库查询标准化,并将其发送至总部。甚至公司的250名信息系统专业人员都平均分为两个阵营,分别支持这两个备选方案。

只在公司分部的局域网中维护保险信息的优点是()

A高公司分部访问保险数据的速度 

B避免由于数据分片而导致失控 

C增加了总部员工对保险信息的访问 

D减少在多个站点备份数据的需求

答案

参考答案:A

解析:

 只在公司分部的局域网中维护保险信息可以增加公司分部访问保险数据的速度,因为常规的重复性事务和查询避免了远距离通信。选项(b)不正确,因为只在公司分部的局域网中维护保险信息意味着由于数据分片可能会失去一些控制。选项(c)不正确,因为仅仅在公司分部的局域网中维护保险信息可能降低总部员工访问保险数据的速度。这是由于要访问存储在公司分部的保险数据需要进行通信。选项(d)不正确,因为即使将保险数据存储在公司分部,一些数据仍然需要在总部进行复制。
