+# Database Update
+
+### Overview
+
+This sample shows how to perform operations on a relational database (RDB) store, including adding, deleting, modifying, and querying data and performing database transactions.
+
+For details, see RDB store.
+
+
+### Preview
+![image](screenshots/device/DataBaseUpgrade_en.gif)
+
+### How to Use
+
+1. Tap the drop-down list box, select an option, and enter the field to add.
+2. Tap **Update**. The progress bar is displayed. If you tap the cross (x) icon before the progress bar reaches 100%, a transaction rollback is performed. As a result, the user information is not updated.
+3. Tap **Update**. The progress bar is displayed. If the progress bar reaches 100%, the transaction is committed and the user information and the backup RDB store are updated.
+
+4. Tap **Roll back**. The RDB store will be rolled back to the previous version.
+
+   You may need to roll back an RDB store when an error occurs during database execution. The RDB store can be rolled back to its previous version only. If the RDB store is updated, you can roll back to the latest version.

+```
+### How to Implement
+
+* The functionalities in this sample are based on the RDB store.
+* The operation of adding field values is implemented based on **executeSql**.
+* The transaction operations are implemented by **commit()** and **rollback()**.
+* Version rollback is implemented based on RDB backup and restore. When the version is updated, the database is backed up. When the version is rolled back, the database is restored.
+
+### Required Permissions

+
+3. The DevEco Studio version must be DevEco Studio NEXT Developer Beta1 or later.
+
+4. The HarmonyOS SDK version must be HarmonyOS NEXT Developer Beta1 SDK or later.
