Oracle Apex is a low-code web application development platform that allows you to create applications quickly and easily. Here’s a step-by-step guide on how to create a new application in Oracle Apex:
- Log in to your Oracle Apex workspace. If you don’t have one, you can create one for free on the Oracle Apex website (https://apex.oracle.com).
- Once you’re logged in, click on the “Create Application” button on the home page.
- In the “Create Application” dialog box, enter a name for your application and select a template from the list of available templates. You can also select a theme for your application at this stage. Click the “Create Application” button to continue.
- In the “Application Builder” interface, you can start building your application. You can add pages, regions, and items to your application by using the drag-and-drop interface. For example, you can add a report region to display data from a database table or a form region to allow users to enter data into a database.
- To add a new page to your application, click on the “Create Page” button on the toolbar. Select the type of page you want to create, such as a blank page, report page, or form page, and enter a name for the page. You can also select a layout template for the page and add regions and items to the page.
- To add a region to a page, click on the “Add Region” button on the page designer. Select the type of region you want to add, such as a report region, form region, or chart region, and configure the region settings.
- To add items to a region, click on the “Add Item” button on the region designer. Select the type of item you want to add, such as a text field, select list, or date picker, and configure the item settings.
- Once you’ve added all the pages, regions, and items you need for your application, you can preview the application by clicking on the “Run” button on the toolbar. You can also publish the application to make it available to other users.
- That’s a brief overview of how to create a new application in Oracle Apex. Here’s an example of how you might use these steps to create a simple application that displays data from a database table:
- Log in to your Oracle Apex workspace and click on the “Create Application” button.
- Enter a name for your application, such as “Employee Directory“, and select the “Desktop Application” template.
- In the “Application Builder” interface, click on the “Create Page” button and select the “Report” page type. Enter a name for the page, such as “Employee List“, and select the “Blank with Attributes” layout template.
- In the “Report Attributes” section, select the “Table” region source and select the database table you want to display data from. You can also configure the report columns and other settings.
- Click on the “Create Page” button again and select the “Form” page type. Enter a name for the page, such as “Employee Details“, and select the “Blank with Attributes” layout template.
- In the “Form Attributes” section, select the “Database Table” form type and select the database table you want to display data from. You can also configure the form fields and other settings.
- Click on the “Run” button to preview the application. You should see a list of employees on the “Employee List” page and a form for editing employee details on the “Employee Details” page.
- To publish the application, click on the “Create Application” button on the toolbar and select “Packaged Application“. This will create a package file that you can install on an Oracle Apex instance.
- To install the packaged application on an Oracle Apex instance, log in to the instance and click on the “App Builder” button. Click on the “Import” button and select the packaged application file you created in the previous step.
- Follow the prompts to import the application, and then open the application to make sure it’s working correctly.
That’s an example of how you might use Oracle Apex to create a simple application. Of course, you can add more features and functionality as needed, and there are many more options and settings available in the Oracle Apex interface. The best way to learn is to experiment and explore the different options and features in the platform. Good luck with your Oracle Apex development!
