Oracle APEX Part 3 - All the Objects in APEX.

In Oracle APEX, "Objects" typically refer to various components or building blocks that you can use to design and develop applications. These elements are fundamental to creating pages, adding functionality, and enhancing user experience within your APEX applications. Here are some key elements you'll commonly work with in Oracle APEX:

1. Pages:

• Pages are the main building blocks of an APEX application. Each page represents a distinct interface or functionality within your application.
• Types of Pages
• 
  
  
  
  

1. Regions:

   • Regions are containers within a page that hold content. They define the layout and appearance of different sections of your page. Examples include Static Content, Interactive Report, Form, Chart, and more.
   • Types of Regions -
   • 
     
     
     
     

2. Items:

   • Items are user interface controls that allow users to input data or make selections. Examples include text fields, select lists, radio buttons, checkboxes, and date pickers.
   • Types of Items -
   • 
     
     
     
     

3. Buttons:

   • Buttons trigger actions within your application, such as submitting a form, navigating to another page, or executing a process.
   • Types of Button -
   • 
     
     
     
     

4. Processes:

   • Processes are server-side actions or logic that execute when certain events occur, such as page load, button click, or form submission.
   • 
     
     
     
     

5. Validation:

   • Validation rules ensure that data entered by users meets specified criteria or format before being processed further.
   • below are some of the validations available-
   • 
     
     
     
     

6. Dynamic Actions:

   • Dynamic Actions enable you to create client-side interactions and behaviors without writing JavaScript code. They respond to user actions like button clicks, item changes, and page load events.
   • 
     
     
     
     

7. Shared Components:

   • Shared Components are reusable elements across multiple pages or applications. Examples include navigation menus, application-level items, and authentication schemes.
   • 
     
     
     
     

8. Charts and Reports:

   • APEX provides built-in components for creating interactive charts and reports based on SQL queries or web services.
   • 
     
     
     
     

9. Themes and Templates:

   • Themes define the overall look and feel of your application, including colors, fonts, and styles. Templates provide pre-defined layouts for pages and regions.
   • 
     
     
     
     

10. Authentication and Authorization:

• APEX includes features for managing user authentication (login/logout) and authorization (access control) to secure your application.
• 
  
  
  
  

These elements collectively enable you to build sophisticated web applications quickly within Oracle APEX, leveraging a combination of declarative development and SQL for backend logic. Understanding how each element works and interacts with others is key to efficiently developing and maintaining your APEX applications.
