centralized file data base 释义集中式文件数据库
The first iteration defines the architecture - is it manual or automated, is it centralized or distributed, is it on-line or batch, is it flat files or a relational data base, etc.
第一个迭代定义体系结构—它是人工的还是自动的，是集中的还是分散的，是在线的还是批命令式的，是直接文件存储还是通过关系性数据库等等。
During that transformation, applications and data sources were physically dispersed across the hardware base, creating a need to link once centralized but now dispersed components.
在这个转变过程中，应用程序和数据源在物理上分散在硬件群体上，这就产生了一种需求，即把过去是集中的、但现在是分散的部件连接起来。
