Hector Garcia-Molina, Jeffrey D. Ullman, and Jennifer Widom, well-known computer scientists at Stanford University, have written an introduction to database systems with a comprehensive approach. The first half of the book provides in-depth coverage of databases from the point of view of the database designer, user, and application programmer. It covers the latest database standards SQL-1999, SQL/PSM, SQL/CLI, JDBC, ODL, and XML, with broader coverage of SQL than most other texts. The second half of the book provides in-depth coverage of databases from the point of view of the DBMS implementor. It focuses on management, covering the principal techniques in these areas with broader coverage of query optimization than most other texts. Advanced topics include multidimensional and bitmap indexes, distributed transactions, and information integration techniques. This comprehensive book is valuable either as an academic textbook or as a professional reference book.

I was pleasantly surprised to find that "Database Systems: the
complete book" is extremely readable and very complete
(living up to its title). The first half of the book covers
database systems at the high level, discussing relational
and object models. Even the chapter on relational algebra is
more readable that other work I've waded through. Every time
a concept is introduced the authors provide an example.
The second half of the book covers database implementation
and archiectural issues (e.g., B-trees and other data
structures for fast database implementation).
The sub-title ("The Complete Book") is not an exageration.
It is a great pleasure to find a book that covers database
systems from the user level to low level disk I/O. The authors
even provide some interesting observations on commercial
database trends. In the excellent chapter on the Object
Definition Language (ODL) and object database systems they
note that the early predictions for object database systems
proved overly optimistic since these systems did not provide
users enough of an advantage over relational systems to
displace these systems in the market.
The authors are professors at Stanford and this book is
a college textbook. The complete coverage of database
systems and the readable nature of this book makes it
an excellent reference for professionals like me who
took database systems long ago and need a complete
current reference.
