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。

在一台计算机中维护保险信息的优点是()

A提高公司分部访问保险数据的速度 

B促使容量大规模增长 

C避免由于数据分片而导致失控 

D为所有用户提高系统可用性
