【问题描述】：

我无法理解逻辑设计和物理设计之间的区别。你能像列出 5 个不同一样解释它们之间的区别吗？

【问题讨论】：

需要更多上下文。 “[list 5]”指的是什么？这有关系吗？就其本身而言，它是没有意义的。

  We usually come up with logical design at high level, using straw-man kind of diagram which you can do in a whiteboard or powerpoint, whereas the physical diagram we use any standard UML diagram based on the need.

  The requirements will be input to the logical diagram, for physical diagram - logical diagram will be the input.

  The logical design is more conceptual and abstract than the physical design. In the logical design, you look at the logical relationships among the objects. In the physical design, you look at the most effective way of storing and retrieving the objects. Your design should be oriented toward the needs of the end users.
