Introduction
Oracle Application Express (APEX) is a low-code development platform that allows you to build web applications quickly and efficiently. In this guide, we will walk you through the steps to create an application in Oracle APEX from start to finish.
Prerequisites
Before you begin, make sure you have the following:
- An Oracle APEX instance installed and configured.
- Access to the Oracle APEX development environment.
- A basic understanding of SQL and PL/SQL.
Guided Tour For Oracle APEX.
Step 1: Log in to Oracle APEX
Open your web browser and navigate to the URL of your Oracle APEX development environment. Enter your login credentials to access the APEX workspace.
Step 2: Create a New Application
- Click on the “App Builder” tab in the top navigation bar.
- Click on the “Create” button to start creating a new application.
- Enter a name and an optional description for your application.
- Choose a template or create a blank application.
- Configure the application settings, such as authentication, theme, and language.
- Click on the “Create” button to create the application.
Step 3: Design the User Interface
Once the application is created, you can start designing the user interface by adding pages, regions, items, and other components.
- Click on the “Pages” tab to manage the pages of your application.
- Click on the “Create” button to add a new page.
- Choose a page type and configure its settings.
- Drag and drop regions and items onto the page to define its layout and content.
- Configure the properties of regions and items as per your requirements.
- Repeat the above steps to create additional pages and design the application flow.
Step 4: Define Application Logic
Next, you can define the application logic by adding processes, validations, and computations.
- Click on the “Shared Components” tab and select “Processes”.
- Click on the “Create” button to add a new process.
- Choose a process type, such as PL/SQL or SQL, and define its settings.
- Write the necessary code or SQL queries to implement the desired functionality.
- Configure any validations or computations to enforce data integrity or perform calculations.
Step 5: Test and Refine the Application
After designing the user interface and defining the application logic, it’s time to test and refine the application.
- Click on the “Run Application” button to preview your application.
- Test the application by interacting with the pages and validating the functionality.
- Make any necessary refinements, such as adjusting the layout, improving usability, or fixing bugs.
Step 6: Deploy the Application
Once you are satisfied with your application, it’s ready to be deployed.
- Click on the “App Builder” tab and select “Packaged Apps”.
- Click on the “Export” button to export your application as a deployment package.
- Choose the appropriate deployment option, such as on-premises or in the cloud.
- Follow the deployment instructions for your chosen option.
Conclusion
Creating an application in Oracle APEX is a straightforward process that allows you to quickly build robust web applications. By following the steps outlined in this guide, you can design, develop, and deploy applications efficiently using the power of Oracle APEX.
