Oracle APEX (Application Express) is a powerful low-code development platform that allows you to build web applications quickly and efficiently. If you’re new to Oracle APEX and eager to get started, this step-by-step guide will walk you through the process of setting up your first APEX application.


Before you begin, make sure you have the following prerequisites in place:

  1. Oracle Database:
    • A running Oracle Database instance. Oracle APEX is tightly integrated with the Oracle Database, so having access to an Oracle Database is essential.
  2. Oracle APEX Workspace:
    • An Oracle APEX workspace. A workspace is a logical grouping of database objects, applications, and users within Oracle APEX.

Step 1: Accessing Oracle APEX : To begin, ensure you have access to an Oracle Database with APEX installed. You can access Oracle APEX through a web browser. Open your browser and enter the URL provided by your Oracle Database administrator, typically in the format: http://<your_database_host>/ords/<workspace_name>/apex.

Step 2: Logging In and Navigating the Workspace : Once the APEX login page appears, enter your credentials. If you’re accessing APEX for the first time, you might need to use the default admin credentials provided during the installation. After logging in, you’ll find yourself in the APEX workspace. Take a moment to explore the navigation menu, where you can access various components such as Applications, SQL Workshop, and Team Development.

Step 3: Creating a New Application : Now that you’re familiar with the workspace, let’s create your first APEX application. Click on the “App Builder” tab, then select “Create” and choose “Database App.” Follow the wizard to configure your application, providing essential details such as the name, workspace, and authentication type. APEX offers different authentication options, so choose one that fits your project requirements.

Step 4: Selecting a Data Source : In this step, you’ll define the data source for your application. APEX makes it easy to connect to your Oracle Database tables or create SQL queries to fetch data dynamically. Choose the appropriate option based on your project needs, and follow the prompts to establish the connection.

Step 5: Building Your First Page : With the application and data source configured, it’s time to create your first page. APEX offers a variety of page types, such as Interactive Reports, Forms, and Charts. Select the page type that aligns with your application’s purpose, and follow the wizard to define the source, layout, and appearance of your page.

With pages in place, you can customize the look and feel of your application. APEX provides a variety of themes and templates to choose from. Experiment with different options until you find a design that suits your preferences.

Dynamic Actions in APEX allow you to create client-side interactions without writing JavaScript code. For example, you can use Dynamic Actions to show or hide page elements based on user actions. Explore the “Dynamic Actions” section to enhance the functionality of your application.

Before deploying your application, it’s crucial to test it thoroughly. APEX provides a built-in “Run” option that allows you to preview your application within the development environment. Test each page and interaction to ensure everything works as expected.

Once you’re satisfied with your application, it’s time to deploy it for wider use. APEX provides deployment options, including exporting your application as a packaged app or deploying it directly to Oracle Cloud. Follow the deployment wizard to make your application accessible to users.

Congratulations! You’ve successfully set up your first Oracle APEX application. This tutorial provides a foundational understanding of the APEX environment and the essential steps to create a basic web application. As you become more familiar with APEX, you can explore advanced features and techniques to build even more sophisticated applications.

Conclusion : Congratulations! You’ve successfully set up your first Oracle APEX application. This is just the beginning of your APEX journey, and there’s much more to explore and learn. In future blog posts, we’ll delve into advanced features, customization options, and best practices for APEX development. Stay tuned for more insights into making the most out of Oracle APEX!
