摘要

1970年埃德加·科德(Edgar Codd)的论文概述了关系数据库模型，这是有关数据的思想的飞跃。最重要的概念之一是数据独立性，即任何数据库的逻辑数据模型和物理存储层之间的区别。下面的摘要给出了内容的概述。我还将简要总结讲座中的关键概念，但这不是详尽的，也不包括练习中的每一个细节。

Lessons Learnt

With the 1970 paper of Edgar Codd outlining a relational database model, a leap in thinking concerning data was made. One of the most important concepts is data independence, namely the distinction between the logical data model and physical storage layer of any database. The summary below gives an overview of the content. I will also briefly summarize key concepts from the lecture, but this is not exhaustive, nor does it include every detail from the exercises.
