Steven Feuerstein's first book, Oracle PL/SQL Programming, has become the classic reference to PL/SQL, Oracle's procedural extension to its SQL language. His new book looks thoroughly at one especially advanced and powerful part of the PL/SQL language -- the package. The use of packages can dramatically improve your programming productivity and code quality, while preparing you for object-oriented development in Oracle technology. In this book, Feuerstein explains how to construct packages -- and how to build them the right way. His "best practices" for building packages will transform the way you write packages and help you get the most out of the powerful, but often poorly understood, PL/SQL language. Much more than a book, Advanced Oracle PL/SQL Programming with Packages comes with a PC diskette containing a full-use software companion. Developed by Feuerstein, RevealNet's PL/Vision Lite is the first of its kind for PL/SQL developers: a library of thirty-plus PL/SQL packages. The packages solve a myriad of common programming problems and vastly accelerate the development of modular and maintainable applications. The packages provided in PL/Vision Lite fall into three categories: Building block packages: low-level development enhancers, including string parsers, a list manager, and an interface to PL/SQL tables. Developer utilities: programs that improve your PL/SQL development environment, including a code generator, a powerful substitute for SHOW ERRORS, and an online help delivery mechanism. Plug-and-play components: pieces of code that can be used as is in your own applications, including a high-level exception handler mechanism and a generic, reusable logging mechanism. In addition to describing the details of these packages, this book explores why and how they were built the way they were. You'll come away with an increased appreciation of the PL/SQL language and the power of packages. Most importantly, you'll be ready and eager to put that power to use immediately in your own applications.

Steven Feuerstein has been having fun with Oracle software since 1987, but nothing prepared him for the Joy of PL/SQL. When not in ecstasies over his latest package creation, Steven is codirector of the Oracle Practice for SSC, a systems management consulting firm based in Chicago. He is also a senior technology officer for RevealNet and coauthor of the Reveal for PL/SQL knowledge base. Finally, Steven is the author of RevealNet's PL/Vision, the first third-party software library for PL/SQL. Steven shares his Rogers Park, Chicago, Georgian with his wife, Veva, his youngest son, Eli, two cats (Sister Itsacat and Moshe Jacobawitz), Mercury the Congo Red African Gray parrot, and the occasional carpenter ant (which Steven would be happy to name, but in ways thoroughly unprintable). He is a member of the Board of Directors of the Crossroads Fund, which provides grants to organizations in Chicago working for social change. Steven is the author of Oracle PL/SQL Programming (O'Reilly & Associates, 1995).
