| + | ==== Lecture 4: More Index Structures ==== | ||
| + | |||
| + | * During Lecture 4 ({{:teaching:infoh417:slides-lect4-part1.pdf|slides part I}}, {{:teaching:infoh417:slides-lect4-part2.pdf|slides part II}}, {{:teaching:infoh417:slides-ch13-indexstruc.odp|slides part II in OpenOffice Impress format}}) we have studied index structures based on hashing, and discussed the typical architecture of a DBMS. The details are found in section 14.3 and 15.7 in the book. | ||
| | | ||
| + | ==== Lecture 5: Multidimensional Index Structures ==== | ||
| + | |||
| + | * During lecture 5 ({{:teaching:infoh417:slides-lect5.pdf|slides}}) we study various index structures that deal gracefully with multidimensional search keys. The details may be found in sections 14.4-14.6, pages 661-688 (in the international edition) or pages 649-676 (in the new international edition) of the book. | ||
