+# Distributed Data Management Subsystem JS API Changelog
+
+## cl.distributeddatamgr.1 API Change
+Changed the **relationalStore** APIs of the distributed data management (distributeddatamgr) subsystem.
+
+Before change:
+After **getRdbStore()** is called, the application determines whether the RDB store is newly created based on the **openStatus** attribute (openStatus == ON_CREATE) of the returned **rdbStore** object.
+After change:
+After **getRdbStore()** is called, the application determines whether the RDB store is newly created based on the **version** attribute (version == 0) of the returned **rdbStore** object.
+
+You need to adapt your application.
+
+ **Change Impact**
+
+The JS APIs of API version 10 are affected and need to be changed accordingly. Otherwise, certain functions cannot be properly implemented in the SDK of the new version.
+

+
+
+**Adaptation Guide**
+
+Refer to the following code to set or obtain the RDB store version for an application:
+
+```ts
+const STORE_CONFIG = {
+    name: "rdbstore.db",
+    securityLevel: data_rdb.SecurityLevel.S1
+}
+data_rdb.getRdbStore(this.context, STORE_CONFIG, function (err, rdbStore) {
+    // Before:
+    // if (rdbStore.openStatus == ON_CREATE) {
+    //     rdbStore.executeSql("CREATE TABLE IF NOT EXISTS student (id INTEGER PRIMARY KEY AUTOINCREMENT, score REAL);", null) // create table xxx
+    // }
+    
+    // Now:
+    if (rdbStore.version == 0) {
+        rdbStore.executeSql("CREATE TABLE IF NOT EXISTS student (id INTEGER PRIMARY KEY AUTOINCREMENT, score REAL);", null) // create table xxx
+        // Set the RDB store version, which is a positive integer greater than 0.
+        rdbStore.version == 3
+    }
+    // Obtain the RDB store version.
+    console.info("Get RdbStore version is " + rdbStore.version)
+})
+```
