Blog 3: Creating My First Oracle APEX Application – Step by Step

 

Introduction

Creating your first application in Oracle APEX is an exciting step for beginners. Oracle APEX makes application development easy using its low-code features while still allowing strong control over database logic. In this blog, I explain how to create your first Oracle APEX application step by step, based on my learning experience.

This guide is ideal for beginners who are starting their journey with Oracle APEX.

Prerequisites

Before creating an Oracle APEX application, you should have:

  • Access to an Oracle APEX workspace

  • Basic knowledge of SQL

  • A web browser (Chrome, Edge, or Firefox)

How to request a free workspace to start developing web applications in oracle apex

Step 1: Login to Oracle APEX Workspace

  1. Open Oracle APEX URL (apex.oracle.com or company workspace)

  2. Enter:

    • Workspace

    • Username

    • Password

  3. Click Sign In

📌 After login, you will see the Oracle APEX Builder Home Page.

Step 2: Create a New Application

  1. Click App Builder

  2. Click Create

  3. Select New Application

  4. Enter:

    • Application Name (e.g., Employee Management System)

  5. Click Create Application

Oracle APEX automatically creates default pages like:

  • Home Page

  • Login Page

Step 3: Add a Page to the Application

  1. Inside App Builder, click Create Page

  2. Choose a page type:

    • Report

    • Form

    • Dashboard

  3. Select Form

  4. Choose table or view

  5. Click Create Page

📌 Oracle APEX automatically generates form items and processes.

Step 4: Configure Page Components

After page creation:

  • Regions are created automatically

  • Page Items are mapped to table columns

  • Buttons like Create, Save, Delete are added

  • Validations and Processes are auto-generated

This saves a lot of development time.

Step 5: Run the Application

  1. Click Run Application

  2. Login using application credentials

  3. Navigate through pages

  4. Insert, update, or view data

🎉 Your first Oracle APEX application is now running!

Understanding APEX processes helped me fix these issues.

Why Oracle APEX is Beginner Friendly

  • Minimal coding required

  • Automatic page creation

  • Built-in security

  • Tight database integration

  • Easy debugging and maintenance

Conclusion

Creating your first Oracle APEX application helps you understand how pages, regions, items, and processes work together. Oracle APEX is an excellent platform for beginners to build real-world, data-driven applications quickly and securely.

This blog is part of my Oracle APEX learning journey, and I will continue sharing more concepts and real-time issues.
