 +==== Reading Assignment 1: Physical data organisation ​ ====
 +
 +   * We take an intermezzo in the compilation of SQL to logical query plans, and consider how a DBMS physically organizes its data on disk.  ({{:​teaching:​infoh417:​slides-ra1.pdf|slides}}). The details may be found in chapter 13 of the book and constitute the first reading assignment.
 +
 +==== Lecture 3: Index Structures ​ ====
 +
 +  * During Lecture 3 ({{:​teaching:​infoh417:​slides-lect3-part1.pdf|slides part I}},  {{:​teaching:​infoh417:​slides-lect3-part2.pdf|slides part II}}) we study sparse and dense index structures, and BTrees. The details are found in chapter 14, sections 14.1 and 14.2 in the book.
 +
 +==== Lecture 4: More Index Structures ​ ====
 +
 +  * During Lecture 4 ({{:​teaching:​infoh417:​slides-lect4-part1.pdf|slides}},​ {{:​teaching:​infoh417:​slides-ch13-indexstruc.odp|slides in OpenOffice Impress format}}) we have studied index structures based on hashing. Hash-based indexes are discussed in depth in section 14.3 and 15.7 in the book.
 +  ​
 +  * In addition, we have also introduced data warehouses {{:​teaching:​infoh417:​slides-lect5.pdf|slides}}) and motivated the need for multidimensional index structures. Subsequently,​ we  and have studied various index structures that deal gracefully with multidimensional search keys. See sections 14.4-14.6, pages 661-688 (in the international edition) or pages 649-676 (in the new international edition) of the book.
