* In lecture 6 ({{:teaching:infoh417:slides-lect6.pdf|slides}}), we study the basic algorithms for physical operators, together with their cost analysis. The details (including some algorithms not discussed during the lecture) can be found in chapter 15 sections 15.1 until 15.6, pages 701-746 (in the international edition) or pages 689-734 (in the new international edition). The interested reader is also advised to read Section 15.7 (although this will not be interrogated during the exam). | * In lecture 6 ({{:teaching:infoh417:slides-lect6.pdf|slides}}), we study the basic algorithms for physical operators, together with their cost analysis.

+ | ==== Lecture 7: Cost-Based Plan Selection ==== | ||
+ | * During lecture 7 ({{:teaching:infoh417:slides-lect7.pdf|slides}}), we study the problems that occur when translating a logical query plan into an (optimal) physical query plan (i.e., estimating the sizes of subresults and join ordering). The details can be found in Chapter 16 (Sections 16.4 until 16.8, pages 792-839 in the international edition or pages 780-827 in the new international edition). | ||

+ | |||
+ | * During lecture 8 {{:teaching:infoh417:slides-lect8-part1.pdf|slides part 1}} {{:teaching:infoh417:slides-lect8-part2.pdf|slides part 2}} we gave a short introduction to transaction processing in general, and dove into coping with systems failures in particular. The details may be found in chapter 17 of the book. | ||

+ | * You are expected to solve the integrated exercise 8.2 of the {{:teaching:infoh417:02-logicalopt-ex.pdf|optimization exercises}}, and 3.5 of the {{:teaching:infoh417:04-costbasedsel-ex.pdf|cost-based plan selection exercises}} by the exercise session of **Friday, December 8**. **It is strongly suggested that you try doing these exercises, as they are typical exam questions.** | ||
+ | * You are expected to solve exercises 17.2.2, 17.2.4, 17.2.5, 17.2.7, 17.3.2, 17.3.3, 17.3.4, 17.3.5, 17.4.2, 17.4.3, 17.4.4, and 17.4.5 in the book by exercise session of **Friday, December 15**. | ||
