Lino Schildenfeld gave an introductory presentation on Oracle Application Express (APEX). He discussed that APEX is a rapid application development tool for Oracle Database that uses a three-tier architecture. Key points included that APEX is a feature of Oracle Database, is ideal for PL/SQL developers, and provides modern web development capabilities like session management and authentication out of the box. Schildenfeld encouraged attendees to try APEX themselves and provided several resources for learning more.

Editor's Notes
- The story is we are manager or rookie developers looking for information. Wanting to join and work with APEX.
- Simple architecture where page requests and submissions made from the browser are tunnelled through the mid-tier to execute in the Oracle Database and returned as HTML responses to the browser. No data manipulation or processing is performed in the mid-tier, instead the APEX engine (inside the Oracle DB) accepts the page, and interacts with the data schemas in the DB. The mid-tier can be either the preferred Oracle REST Data Services (ORDS) running in a Java Server {either Oracle Web-Logic Server (WLS), Oracle Glassfish, or Tomcat} or Oracle Embedded PL/SQL Gateway (EPG) which is part of the Oracle DB, or Oracle HTTP Server (OHS) with mod_plsql. It is common for OHS to be installed in front of ORDS to act as a proxy and serve images.
- Workspace is place where you build applications. It can be connected to one ore multiple DB schemas.
