Oracle development tools come and go, but one of the few constants in the Oracle database environment is the PL/SQL programming language, which has been around for more than a decade. As Oracle's premier tool for building store procedures, PL/SQL supplements the standard database language, SQL, with the features needed to build real-world applications. This volume is suitable for newcomers to the language. It begins with a discussion of what PL/SQL is and what it's good for, and then presents language features, one at a time. A consistent and understandable example - the development of a library's electronic catalogue system - runs through the chapters.
Steven Feuerstein is considered one of the world's leading experts on the Oracle PL/SQL language. He is the author or coauthor of six books on PL/SQL, including the now-classic Oracle PL/SQL Programming and Oracle PL/SQL Best Practices, all from O'Reilly & Associates. Steven is a Senior Technology Advisor with Quest Software, has been developing software since 1980, and worked for Oracle Corporation from 1987 to 1992. Steven is president of the Board of Directors of the Crossroads Fund, which makes grants to Chicagoland organizations working for social, racial and economic justice.
