    (3) Create an RDB store.
 
-   The sample code is as follows:
+   FA model:
 
     ```js
-    import data_rdb from '@ohos.data.rdb'
+   import data_rdb from '@ohos.data.rdb'
+    // Obtain the context.
+   import featureAbility from '@ohos.ability.featureAbility'
+   let context = featureAbility.getContext()
+
+   const CREATE_TABLE_TEST = "CREATE TABLE IF NOT EXISTS test (" + "id INTEGER PRIMARY KEY AUTOINCREMENT, " + "name TEXT NOT NULL, " + "age INTEGER, " + "salary REAL, " + "blobType BLOB)";
 
-    const CREATE_TABLE_TEST = "CREATE TABLE IF NOT EXISTS test (" + "id INTEGER PRIMARY KEY AUTOINCREMENT, " + "name TEXT NOT NULL, " + "age INTEGER, " + "salary REAL, " + "blobType BLOB)";
-    const STORE_CONFIG = { name: "rdbstore.db" }
-    data_rdb.getRdbStore(this.context, STORE_CONFIG, 1, function (err, rdbStore) {
+   const STORE_CONFIG = { name: "RdbTest.db" }
+   data_rdb.getRdbStore(context, STORE_CONFIG, 1, function (err, rdbStore) {
       rdbStore.executeSql(CREATE_TABLE_TEST)

+   import data_rdb from '@ohos.data.rdb'
+    // Obtain the context.
+   import Ability from '@ohos.application.Ability'
