Databases: Relational Databases and SQL
This course is one of five self-paced courses on the topic of Databases, originating as one of Stanford's three inaugural massive open online courses released in the fall of 2011. The original "Databases" courses are now all available on edx.org.
This course provides an introduction to relational databases and comprehensive coverage of SQL, the long-accepted standard query language for relational database systems.

Advanced Topics is a broad and practical course covering indexes, transactions, constraints, triggers, views, and authorization, while OLAP and Recursion is recommended for learners with specific interest in these topics.

Preguntas frecuentes
How long will it take to go through the course material?
All of the courses are self-paced and include videos, quizzes, and/or exercises. The courses vary considerably in length and complexity, and some students work faster than others, so we're not able to predict an individual time commitment.
What background do I need?
The series of courses does not assume prior knowledge of any specific topics, however a solid computer science foundation -- a reasonable amount of programming, as well as knowledge of basic computer science theory -- will make the material more accessible.
Do I need to buy a textbook?
Detailed lecture notes are provided. Having a textbook in addition to the notes is not necessary, but you might want to purchase one for reference, to reinforce the core material, and as a source of additional exercises. Suggested textbooks and readings are listed as part of the materials.
