System analysis and system design are divided into following processes: system requirement, requirement analysis, the system static modeling, the system dynamic modeling and physical modeling.

系统分析和设计划分为如下过程：系统需求，需求分析，系统静态建模，系统动态建模。

Since the business computing environment changes from time to time, the separation of logical and physical data modeling will help stabilize the logical models from phase to phase.

因为业务计算环境随时间变化，所以逻辑和物理数据建模的分离将帮助稳定一个阶段到另一阶段的逻辑模型。

There are three levels of data modeling: conceptual, logical, and physical.

数据建模有三层：概念、逻辑和物理。
