Declarative Programming

With Application Express, coding is declarative. That means that no code is generated, no code is compiled, and you interact with wizards and property sheets. The SQL language is used to define reports and charts, so some knowledge of SQL is very helpful. You can optionally write snippets of code using PL/SQL, if procedural logic is needed. Declarative code yields fewer differences between developers and this consistency makes Application Express applications easy to maintain and manage.
