Use Case: Offline Data Access

Scenario 1: Viewing Customer Information While Offline

Data Retrieval: A field worker uses the Fetch Offline DB action to access customer information without an internet connection.
Data Access: The worker can view customer information in the local database, but since there is no internet connection, the data is limited to the latest information stored on the device.
Result: The employee can interact with and process data while offline.

Scenario 2: Viewing Order Information While Offline

Data Retrieval: While offline, a user retrieves old order information from the local database using the Fetch Offline DB action.
Data Viewing: Since there is no internet connection, the user can only see the data stored in the local database.
Result: The user can view old order information while offline and perform operations on this data as needed.

Fetch Offline DB Action Advanced Customisations

Data Access Timing: You can perform automatic data updates by triggering the Fetch Offline DB action before the user accesses data while offline.
Data Filtering: You can use additional parameters to filter the retrieved data according to specific criteria.
Data Synchronisation: You can use the Fetch Offline DB action to present the latest data from the local database to the user before synchronising the data retrieved while offline with the server.

Technical Risks

Data Updates: To prevent data retrieved while offline from conflicting with current data, add conflict management during data updates.
Data Errors: Before processing data while offline, create data validation processes to prevent data loss or incorrect data retrieval.

The Fetch Offline DB action provides access to data in the local database while offline. Users can easily access, view, and interact with data in the database even when there is no internet connection. This action facilitates offline data management, especially in mobile applications, providing a seamless user experience.
