CREATING AN APPLICATION IN ORACLE APEX

Introduction

Oracle APEX (Application Express) provides a powerful, browser-based environment to rapidly create modern web applications backed by an Oracle database. Whether you're building an internal tool, a data-driven dashboard, or a full-scale business solution, creating an application in APEX is a guided, low-code experience. This blog post will walk you through the essential steps to create your first application in Oracle APEX and offer best practices to help ensure your project starts on the right path.

How to Create an Application in Oracle APEX

1. Log in to Oracle APEX
   Begin by signing in to your APEX workspace via your browser. You can access Oracle APEX either through Oracle Cloud, Oracle Autonomous Database, or a local APEX installation.

2. Navigate to App Builder
   On the APEX home page, click on “App Builder.” This is where all your applications are managed and created.

3. Click on “Create” to Start a New Application
   Choose one of the following:

   • New Application – to build an app from scratch.

   • From a File – to build an app from a spreadsheet or CSV.

   • From a Template App – to start from an Oracle-supplied sample application.

4. Define Application Details

   • Enter a name for your application.

   • Optionally, specify a schema (if you have multiple).

   • Set the application ID (leave it auto-generated unless needed otherwise).

   • Choose an application appearance (theme, icon, etc.).

5. Add Pages
   Oracle APEX will prompt you to add pages:

   • You can choose from Forms, Reports, Charts, Calendars, Dashboards, etc.

   • Use the wizard to configure each page’s data source and layout.

6. Set Features (Optional)

   • Enable features like Activity Reports, Feedback, Access Control, or RESTful Web Services.

   • These features can be added now or later via App Builder.

7. Review and Create

   • Review all application configurations.

   • Click Create Application.

   • Once created, you can click Run Application to see it in action.

8. Login to Application
   The default login uses the APEX workspace credentials. You can configure custom authentication later as needed.

Best Practices

• Use clear and descriptive naming for applications, pages, and components.

• Start with fewer features and expand incrementally.

• Enable user activity logs and feedback features to capture early user insights.

• Implement proper authentication and authorization schemes from the beginning.

• Regularly back up your application and export versions as needed.

• Test thoroughly on various devices and screen sizes using the responsive design preview.
