课程详情
"Introduction to Databases" had a very successful public offering in fall
2011, as one of Stanford's inaugural three massive open online courses.
Since then, the course materials have been improved and expanded, and all
materials are available for self-study. Students have access to lectures
with in-video quizzes, multiple-choice quiz assignments, automatically-checked
interactive programming exercises, midterm and final exams, a discussion
forum, optional additional exercises with solutions, and pointers to readings
and resources. Taught by Professor Jennifer Widom, the curriculum draws
from Stanford's popular Introduction to Databases course. The material
presented here is the same as the corresponding material presented on Stanford's
Class2Go platform.
Why Learn About Databases?
Databases are incredibly prevalent -- they underlie technology used by
most people every day if not every hour. Databases reside behind a huge
fraction of websites; they're a crucial component of telecommunications
systems, banking systems, video games, and just about any other software
system or electronic device that maintains some amount of persistent information.
In addition to persistence, database systems provide a number of other
properties that make them exceptionally useful and convenient: reliability,
efficiency, scalability, concurrency control, data abstractions, and high-level
query languages. Databases are so ubiquitous and important that computer
science graduates frequently cite their database class as the one most
useful to them in their industry or graduate-school careers.
课程大纲
This course covers database design and the use of database management
systems for applications. It includes extensive coverage of the relational
model, relational algebra, and SQL. It also covers XML data including DTDs
and XML Schema for validation, and the query and transformation languages
XPath, XQuery, and XSLT. The course includes database design in UML, and
relational design principles based on dependencies and normal forms. Many
additional key database topics from the design and application-building
perspective are also covered: indexes, views, transactions, authorization,
integrity constraints, triggers, on-line analytical processing (OLAP),
JSON, and emerging "NoSQL" systems.

作业非常有趣，问题需要动脑筋，但又不是特别难，整个过程像玩智力游戏一样。缺点是本课应用向的东西很少，没有proj，主要是讲SQL，编程作业也是给个数据库让你写检索的代码。我们学校这门课用的教材就是这个Prof.参与编写。

這門課後來從Coursera上搬到了斯坦福的Class2go上，當時特意買了Jeffery Ullman & Jennifer Widom的教材，後來發現也是基本用不上，Jennifer Widom的講解特別清晰。我比較喜歡Class2go的網頁編程題，對於我這種初學者挺花時間，但也很有收獲。課程的內容不僅包括了傳統的SQL,還有XML,JSON等，並附有相關練習。他們的論壇也很好，在上面問問題反饋非常及時。如果要說缺點的話，那就是Class2go的頁面佈局確實沒有Coursera好，感覺挺亂的。說一點小八卦，Jennifer Widom的丈夫在Coursera上也開課，就是斯坦福的那門Compiler

2011年冬天有3门公开课的诞生足以载入史册，一个是Andrew Ng的“机器学习”，一个是Sebastian Thrun和Peter Norvig的“人工智能导论”，还有一个就是这门“数据库导论”。在这几门课一鸣惊人之后，Andrew Ng联合Daphne Koller创办了Coursra, 而Thrun和Norvig择创办了Udacity。
不知道当年有多少同学学习了这门数据库导论课程，而这门课程目前在Coursra上是少数几个可以“自主学习”的课程，就是随时可以学习的课程，不过不能拿证书，但是这又有什么呢? 我们是来学习知识的。
