逻辑数据模型的一般设计目标是正确性、一致性、非冗余和简单性。
The general design objectives of the logical data model are correctness, consistency, non-redundancy and simplicity.
从这一阶段开始，该解决方案就适用自底向上的方法了，这意味着这个逻辑数据模型中仅仅将最重要和紧迫的业务主题领域锁定为目标。
Starting from this stage, this solution is adapting the bottom-up approach, which means that only the most important and urgent business subject areas are targeted in this logical data model.
本节展示如何使用一个物理模型及其对象来实现这个目标——对于逻辑模型也可以使用类似的方法。
This section shows you how to do this using a physical model and its objects. A similar approach can be used for logical models as well.
