Publisher's Synopsis
This title is about putting Java to work in the Oracle database. It concentrates on real-world applications that developers can put to immediate use in their day-to-day jobs and, in addition, gives in-depth consideration to the question of when it is appropriate to use Java from a performance perspective (including benchmarks). The examples in the book clearly distinguish between situations where Java can provide functionality that PL/SQL cannot. It exploits Java's capabilities for accessing system resources outside the database - such as operating system commands and network sockets. We also make use of powerful Java Utilities for messaging and generating graphics. For example, an application whereby a pie chart image is generated from a query, and then automatically distributed to interested parties (using JavaMail) is developed.;The book is divided into four sections: section I is a fast-paced Java tutorial for PL/SQL programmers; section II covers database access with JDBC and SQLJ and shows how to smoothly and correctly convert between Java and native SQL data types; section III is the real heart of the book, where what has been learned is applied to practical problem solving with Java and PL/SQL; and section IV takes a detailed look at performance issues. Having considered Java application tuning and SQL tuning separately, the book takes a detailed look behind the scenes of Java database access and tries to illustrate how you should choose between Java and PL/SQL for database operations. This book is for experienced Oracle developers looking to understand the advantages that Java brings and to exploit them in conjunction with SQL and PL/SQL. It will also be of interest to DBAs looking to understand how Java is likely to be used inside the database and how this affects them, and beginner/intermediate Java Developers looking to apply their knowledge in the Oracle arena.
