Here you can find the <em><strong>tentative</strong></em> schedule of the class (which might change as the semester progresses). The textbook we use is also referred to as the "<a href="http://pages.cs.wisc.edu/~dbbook/" target="_blank">cow book</a>" (see more details in the <a href="https://docs.google.com/document/d/1HJnkBz8NW1W2-6PdoDHij2P2oAP_QOKeAm0L7fEkXqQ/export?format=pdf&attachment=false" target="_blank">syllabus</a>).
Note that by <i class="fa fa-book" aria-hidden="true"></i> we refer to the textbook, by <i class="fa fa-file-text-o" aria-hidden="true"></i> to additional readings, and by <i class="fa fa-external-link" aria-hidden="true"></i> to other links.

The slides will be uploaded here after each class, but they <em>cannot</em> be used as a replacement of the lectures, and will <em>not</em> be sufficient on their own. Some lectures might deviate from the textbook (in presentation, order, and content). Hence, attendance during the lecturing and during the class discussion is <em>mandatory</em> and an integral part of the class.
