How do you implement custom data import and export functionality in SilverStripe?

Answer: To implement custom data import and export functionality in SilverStripe, you would typically follow these steps:

1. Create a Custom Module: Start by creating a custom module to encapsulate your import/export logic.

2. Define Data Models: Ensure you have the appropriate DataObjects defined for the data you want to import/export.

3. Use CSV/JSON or XML: Decide on the data format (CSV, JSON, or XML) for import/export and implement parsing logic accordingly.

4. Build Import/Export Controllers: Create controllers that handle HTTP requests for importing and exporting data. Use `SS_HTTPRequest` to manage file uploads or downloads.

5. Implement Logic: In these controllers, implement logic to read from uploaded files, validate the data, and save it into the database for imports. For exports, convert DataObject records into your chosen format and output them for download.

6. Set Up Permissions: Ensure that only authorized users can access the import/export functionality by setting appropriate permissions.

7. Testing: Thoroughly test the import and export processes to handle edge cases and errors gracefully.

8. User Interface: Optionally, create a user-friendly interface in the CMS for users to manage their imports/exports.

This results in a custom solution tailored to your specific data requirements in SilverStripe.
