   * During lecture 1 ({{:teaching:infoh417:slides-lect1.pdf|slides}}), we present an overview of the architecture of a query compiler (see chapter 16, sections 16.1, 16.3.1 and  16.3.2 in the book) and study the translation of SQL into the extended relational algebra (see {{:teaching:infoh417:sql2alg_eng.pdf|course notes}} for the full translation algorithm).

In addition, we discuss popular heuristics for improving general logical query plans: see chapter 16, section 16.3.3 in the book which discusses the simple (but very important) logical optimizations of “pushing” selections and projections; and recognizing joins, based on the algebraic equalities from section 16.2.

 ==== 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
