Advanced Oracle APEX Training (APEX201)

This advanced APEX course provides an in-depth exploration of Oracle Application Express (APEX), focusing on advanced features and best practices for building and managing robust applications. It is tailored for developers and database administrators who already have a basic understanding of APEX and are looking to enhance their skills in areas such as session state management, data loading, security, navigation, and more.

The course begins with an overview of session state in APEX, explaining the difference between persisted and in-memory session states and providing a visual illustration of how session state functions within the platform.

Next, you will delve into data loading, learning how to create applications, define data load processes, and manage data imports using wizards and API processes. You'll also explore error handling, data transformation, and working with collections. The course includes practical exercises on loading data from CSV files and building data load wizards.

The Advanced Security module covers crucial topics like custom authentication and authorization, form processing, and implementing strong password validation. You will learn strategies for password management, preventing SQL injection, and cross-site scripting, along with how to set up LDAP and Virtual Private Database (VPD) for enhanced security.

The Navigation section provides detailed instruction on creating dynamic navigation components, using the APEX_PAGE.GET_URL function, and setting up navigation menus and breadcrumbs. You will also work on exercises that reinforce these concepts through practical application.

Charting is another key focus, with lessons on different chart types, creating bar and pie charts, and dynamically altering chart settings. The Interactive Grids module teaches you how to enhance data load wizards by incorporating interactive grids.

Themes and Templates will guide you in customizing the look and feel of your APEX applications, including exercises on creating new themes and establishing best practices for template management.

You will also learn about building APEX plug-ins, with exercises to create and implement custom plug-ins, as well as advanced dynamic actions that execute both client-side and server-side code, enhancing the interactivity of your applications.

Additional modules cover working with files, using APEX Office Print (AOP) for document generation, and managing RESTful services, where you will create RESTful data services and interact with REST APIs. The course includes practical exercises to solidify your understanding of these concepts.

The Application Change Management module teaches you how to manage working copies of your applications, merge changes, and refresh copies, ensuring efficient and controlled development workflows.

The course concludes with Troubleshooting and Debugging, focusing on best practices for logging, debugging, and error handling in APEX. You'll learn how to use the APEX debugging tools and write debug messages, helping you identify and resolve issues effectively.

By the end of this course, you'll have advanced skills in APEX, enabling you to build, secure, and maintain complex applications with confidence and precision.
