The purpose of this manual is to give guidance on how to use the eighth edition of the book An Introduction to Database Systems──referred to throughout the manual as simply "the book," or "this book," or "the present book," or just "the eighth edition"──as a basis for teaching a database course. The book is suitable for a primary (one- or two-semester) course at the junior or senior undergraduate or first-year graduate level; it also contains some more forward-looking and research-oriented material that would be relevant to a more advanced course | h Il I I I I N S T R U C T O R S M A N U A L I i I II II f o r h Il I I I A n I n t r o d u c t i o n I I I I t o I I I I D a t a b a s e S y s t e m s I I I I I I I I I I I I Eighth Edition I I I I I by C.

Students are expected to have a basic understanding of a the storage and file management capabilities indexing hashing etc. of a modern computer system and b the features of a typical high-level programming language Java Pascal C PL I etc. . Let me immediately say a little more regarding these two prerequisites 1. In connection with the first please note that although the book proper contains nothing on the subject there s an online appendix available Appendix D Storage Structures and Access Methods that does provide a tutorial overview of such matters. That appendix is an upgraded version of material that was included in the book proper in the first six editions. But file management isn t specific to database systems what s more it s a huge subject in its own right and it has textbooks of its own see .
