This book covers everything you need to know to master Web application development in an Oracle environment - using PL/SQL. It is packed with practical tips that save the reader time, effort and frustration while developing and deploying Internet-ready, e-commerce applications using Oracle 9i. The book also provides important information on core topics such as HTML, Java, XML, WML, Perl and PHP, as well as covering various maintenance duties, such as troubleshooting, debugging, indexing, testing and site analysis. As Oracle's premier tool for building store procedures, PL/SQL uniquely supplements the standard relational database language, SQL, with the features needed to build real-world applications.
