+# Reading and Writing a KV Store
+
+### Overview
+
+This sample demonstrates how to use @ohos.data.distributedKVStore APIs to access a Key-Value (KV) store and add, delete, modify, and query records in it.
+

+
+
+How to Use
+
+1. Select the data level, determine whether to encrypt the data, and touch Create. The details page is displayed.
+2. Touch Add to display a window for adding KV pairs. You can customize the type, key, and value.
+3. Touch Submit to add a data record to the database. (Every key must be unique). Then you can touch the × icon in the upper right corner or the mask area to exit. The data is not updated.
+4. Touch Delete to delete the data record from the database.
+5. Touch Edit to display the editing page. You can modify the data type and value, but cannot change the key name.
+6. Touch Submit. The data in the database is updated.

+
+### How to Implement
+1. Call createKVManager() to create a KVManager instance for database management.
+2. Call getKVStore() and specify options and storeId to create and obtain a KV store of the SingleKVStore type.
+3. Call put() to add a KV pair of a specified type to the database.
+4. Call getEntries() to obtain all keys.
+5. Call delete() to delete data of specified key from the database.

 ### 具体实现
 
-1. 使用createKVManager()接口，创建一个KVManager对象实例，用于管理数据库对象。（实现代码：[](entry/src/main/ets/common/utils/KVStore.ets)）
-2. 使用getKVStore()接口，指定options和storeId，创建并得到SingleKVStore类型的KVStore数据库。（实现代码：[](entry/src/main/ets/common/utils/KVStore.ets)）
-3. 使用put()接口，添加指定类型的键值对到数据库。（实现代码：[](entry/src/main/ets/common/utils/KVStore.ets)） 
-4. 使用getEntries()接口，获取所有键值。（实现代码：[](entry/src/main/ets/common/utils/KVStore.ets)） 
-5. 使用delete()接口，从数据库中删除指定键值的数据。（实现代码：[](entry/src/main/ets/common/utils/KVStore.ets)）
