Oracle Application Express is an easy-to-use application development environment built on the Oracle
technology stack. There are two aspects of that previous sentence that you may find jarring — that
Oracle, a company widely known for its database technology, has an application development environment,
and that Oracle, a company thought of as delivering high-end, enterprise-ready technology, has
anything that is easy to use.
But, as this book will show, the introductory statement is completely accurate. Oracle Application Express,
commonly known as Oracle APEX or simply APEX, does benefit from the long-established enterpriseclass
robustness that is the hallmark of Oracle technology. The applications you build will be able to
support hundreds of users and many terabytes of data, scalability far beyond even the imagination of
most other development environments.
