What is required for using an External Data Object Table from Heroku in Salesforce?

Using an External Data Object Table from Heroku in Salesforce necessitates that it be validated and synced. This process is crucial because it ensures that the data structure and relationships in Heroku are accurately reflected within Salesforce. Validation confirms that the data aligns with the requirements of Salesforce, while syncing enables real-time or scheduled data updates, ensuring that the information in Salesforce remains current and consistent with Heroku's database.

The requirement of syncing and validating helps facilitate seamless integration, allowing Salesforce to treat external data similarly to native Salesforce data, providing users with the ability to work with Heroku data without needing to manually import or export the information. Proper management of this connection enhances data integrity and user experience when interacting with external data sources.
