## When to Use<a name="section18502174174019"></a>
You can set your application to call the **ReminderRequest** class to create scheduled reminders for countdown timers, calendar events, and alarm clocks. When the created reminders are published, the timing and pop-up notification functions of your application will be taken over by the reminder agent in the background, even when your application is frozen or exits.
## Available APIs<a name="section1633115419401"></a>

**Encrypting an RDB Store**
You can encrypt an RDB store.
When creating an RDB store, you can add a key for security purposes. After that, the RDB store can be accessed only with the correct key. You can change the key but cannot delete it.
Once an RDB store is created without a key, you cannot add a key any longer.

## How to Develop<a name="section116922712311"></a>
1. Create an RDB store.
1. Configure the RDB attributes, including the name and storage mode of the database and whether it is read-only.
2. Initialize the table structure and related data in the database.
3. Create an RDB store.
The sample code is as follows:
```
import dataRdb from '@ohos.data.rdb';
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",}
let rdbStore = await dataRdb.getRdbStore(STORE_CONFIG, 1);
await rdbStore.executeSql(CREATE_TABLE_TEST);
```
2. Insert data.
1. Create a **ValuesBucket** object to store the data you need to insert.
2. Call the **insert\(\)** method to insert data into the RDB store.
The relational database \(RDB\) manages data based on relational models. With the underlying SQLite database, the RDB provides a complete mechanism for managing local databases. To satisfy different needs in complicated scenarios, the RDB offers a series of methods for performing operations such as adding, deleting, modifying, and querying data, and supports direct execution of SQL statements.
A type of database based on the relational model of data. The RDB stores data in rows and columns. An RDB is also called RDB store.
-**Predicate**
A representation of the property or feature of a data entity, or the relationship between data entities. It is mainly used to define operation conditions.
-**Result set**
A set of query results used to access the data. You can access the required data in a result set in flexible modes.
-**SQLite database**
A lightweight open-source relational database management system that complies with Atomicity, Consistency, Isolation, and Durability \(ACID\).
## Working Principles<a name="section4810552814"></a>
The RDB provides a common operation interface for external systems. It uses the SQLite as the underlying persistent storage engine, which supports all SQLite database features.

# Lightweight Data Store Development<a name="EN-US_TOPIC_0000001230830543"></a>
## When to Use<a name="section13841104521714"></a>
The lightweight data store is ideal for storing lightweight and frequently used data, but not for storing a large amount of data or data with frequent changes. The application data is persistently stored on a device in the form of files. Note that the instance accessed by an application contains all data of the file. The data is always loaded to the memory of the device until the application removes it from the memory. The application can perform data operations using the **Storage** APIs.
## Available APIs<a name="section15173156141712"></a>
The lightweight data store provides applications with data processing capability and allows applications to perform lightweight data storage and query. Data is stored in key-value pairs. Keys are of the string type, and values can be of the number, string, or Boolean type.
**Creating a Storage Instance**
Create a **Storage** instance for data operations. A **Storage** instance is created after data is read from a specified file and loaded to the instance.
**Table 1** API for creating a **Storage** instance

## How to Develop<a name="section146940394256"></a>
1. Import **@ohos.data.storage** and related modules to the development environment.
```
import dataStorage from '@ohos.data.storage'
import featureAbility from '@ohos.ability.featureAbility' // Used to obtain the file storage path.
```
2. Create a **Storage** instance.
Read the specified file and load its data to the **Storage** instance for data operations.
```
var context = featureAbility.getContext()
var path = await context.getFilesDir()
let promise = dataStorage.getStorage(path + '/mystore')
```
1. Write data.
Use the **put\(\)** method of the **Storage** class to write data to the cached **Storage** instance.
```
promise.then((storage) => {
let getPromise = storage.put('startup', 'auto') // Save data to the Storage instance.
getPromise.then(() => {
console.info("Put the value of startup successfully.")
}).catch((err) => {
console.info("Put the value of startup failed with err: " + err)
})
}).catch((err) => {
console.info("Get the storage failed")
})
```
1. Read data.
Use the **get\(\)** method of the **Storage** class to read data.
```
promise.then((storage) => {
let getPromise = storage.get('startup', 'default')
getPromise.then((value) => {
console.info("The value of startup is " + value)
}).catch((err) => {
console.info("Get the value of startup failed with err: " + err)
})
}).catch((err) => {
console.info("Get the storage failed")
})
```
1. Store data persistently.
Use the **flush** or **flushSync** method to flush data in the **Storage** instance to its file.
```
storage.flush();
```
2. Observe data changes.
Specify **StorageObserver** as the callback to subscribe to data changes for an application. When the value of the subscribed key is changed and the **flush\(\)** method is executed, **StorageObserver** will be invoked. Unregister the **StorageObserver** when it is no longer required.
```
promise.then((storage) => {
var observer = function (key) {
console.info("The key of " + key + " changed.")
}
storage.on('change', observer)
storage.putSync('startup', 'auto') // Modify data in the Storage instance.
storage.flushSync() // Trigger the StorageObserver callback.
storage.off(...change..., observer) // Unsubscribe from the data changes.
}).catch((err) => {
console.info("Get the storage failed")
})
```
1. Delete the specified file.
Use the **deleteStorage** method to delete the **Storage** singleton of the specified file from the memory, and delete the specified file, its backup file, and damaged files. After the specified files are deleted, the application cannot use that instance to perform any data operation. Otherwise, data inconsistency will occur. The deleted data and files cannot be restored.
```
let promise = dataStorage.deleteStorage(path + '/mystore')
# Lightweight Data Store Overview<a name="EN-US_TOPIC_0000001230752103"></a>
Lightweight data store is applicable to access and persistence operations on the data in key-value pairs. When an application accesses a lightweight **Storage** instance, data in the **Storage** instance will be cached in the memory for faster access. The cached data can also be written back to the text file for persistent storage. Since file read and write consume system resources, you are advised to minimize the frequency of reading and writing persistent files.
A type of data structure. The key is the unique identifier for a piece of data, and the value is the specific data being identified.
-**Non-relational database**
A database not in compliance with the atomicity, consistency, isolation, and durability \(ACID\) database management properties of relational data transactions. The data in a non-relational database is independent.
## Working Principles<a name="section682631371115"></a>
1. When an application loads data from a specified **Storage** file to a **Storage** instance, the system stores the instance in the memory through a static container. Each file of an application or process has only one **Storage** instance in the memory, till the application removes the instance from the memory or deletes the **Storage** file.
2. When obtaining a **Storage** instance, the application can read data from or write data to the instance. The data in the **Storage** instance can be flushed to its **Storage** file by calling the **flush** or **flushSync** method.
**Figure 1** How lightweight data store works<aname="fig1657785713509"></a>
-**Storage** instances are loaded to the memory. To minimize non-memory overhead, the number of data records stored in a **Storage** instance cannot exceed 10,000. Delete the instances that are no longer used in a timely manner.
- The key in the key-value pairs is of the string type. It cannot be empty or exceed 80 characters.
- If the value in the key-value pairs is of the string type, it can be empty or contain a maximum of 8192 characters.
