APEX_APPLICATION_INSTALL The APEX_APPLICATION_INSTALL package provides a number of methods to modify application attributes during the Application Express application installation process. See "APEX_APPLICATION_INSTALL".
APEX_COLLECTION

Collections enable you to temporarily capture one or more nonscalar values. You can use collections to store rows and columns currently in session state so they can be accessed, manipulated, or processed during a user's specific session. You can think of a collection as a bucket in which you temporarily store and name rows of information. See "APEX_COLLECTION".
APEX_CSS The APEX_CSS package provides utility functions for adding CSS styles to HTTP output. This package is usually used for plug-in development. See "APEX_CSS".
APEX_DEBUG_MESSAGE The APEX_DEBUG_MESSAGE package provides utility functions for managing the debug message log. See "APEX_DEBUG_MESSAGE".
APEX_JAVASCRIPT The APEX_JAVASCRIPT package provides utility functions for adding dynamic JavaScript code to HTTP output. This package is usually used for plug-in development. See "APEX_JAVASCRIPT".
APEX_PLUGIN The APEX_PLUGIN package provides the interface declarations and some utility functions to work with plug-ins. See "APEX_PLUGIN".
APEX_PLUGIN_UTIL The APEX_PLUGIN_UTIL package provides utility functions that solve common problems when writing a plug-in. See "APEX_PLUGIN_UTIL".
APEX_WEB_SERVICE

The APEX_WEB_SERVICE API allows you to integrate other systems with Application Express by allowing you to interact with Web services anywhere you can utilize PL/SQL in your application. The API contains procedures and functions to call both SOAP and RESTful style Web services. It contains functions to parse the responses from Web services and to encode/decode into SOAP friendly base64 encoding. See "APEX_WEB_SERVICE".
