# 1.1 信息系统与信息化-1 #

## 1.1.1 信息的基本概念 ##

### (1) 信息质量属性 ###

## 1.1.2 信息系统的基本概念(无重要考点) ##

## 1.1.3 信息化的基本概念 ##

### (1) 信息化从"小"到"大"的五个层次 ###

## 1.1.4 信息系统生命周期(\*\*\*\*考1分) ##

### (1) 大的方面-4大 ###

*  立项: 系统规划
 *  开发: 系统分析, 系统设计, 系统实施
 *  运维
 *  消亡

### (2) 小的方面-5小 ###

*  系统规划: 可行性分析与开发计划
 *  系统分析: 需求分析, **提出新系统的逻辑模型**
 *  系统设计: 概要设计, 详细设计, **提出系统的物理模型**
 *  系统实施: 编码, 测试
 *  运行维护
