The ability framework model has two forms.
- FA model, which applies to application development using API version 8 and earlier versions. In the FA model, there are Feature Ability (FA) and Particle Ability (PA). The FA supports Page abilities, and the PA supports Service, Data, and Form abilities.
- Stage model, which is introduced since API version 9. In the stage model, there are Ability and ExtensionAbility. The ExtensionAbility is further extended to ServiceExtensionAbility, FormExtensionAbility, DataShareExtensionAbility, and more.

- Stage model, which is introduced since API version 9. In the stage model, there is `Ability` and `ExtensionAbility`. `ExtensionAbility` is further extended to `ServiceExtensionAbility`, `FormExtensionAbility`, `DataShareExtensionAbility`, and more.
The stage model is designed to make it easier to develop complex applications in the distributed environment. The table below lists the design differences between the two models.

### Creating a Callee
For the callee, implement the callback to receive data and the methods to marshal and unmarshal data. When data needs to be received, use the **on** API to register a listener. When data does not need to be received, use the **off** API to deregister the listener.
1. Configure the ability startup mode.

# DataShare Development
The **DataShare** module allows an application to manage its own data and share data with other applications. Currently, data can be shared only between the applications on the same device.
## Available APIs
**Table 1** APIs of the data provider
|API|Description|
|:------|:------|
|onCreate?(want: Want, callback: AsyncCallback&lt;void&gt;): void|Called to initialize service logic when the data provider application is created, for example, when a database is created.|
|insert?(uri: string, valueBucket: ValuesBucket, callback: AsyncCallback&lt;number&gt;): void|Inserts data into the database.|
|update?(uri: string, predicates: DataSharePredicates, valueBucket: ValuesBucket, callback: AsyncCallback&lt;number&gt;): void|Updates data in the database.|
|query?(uri: string, predicates: DataSharePredicates, columns: Array&lt;string&gt;, callback: AsyncCallback&lt;Object&gt;): void|Queries data from the database.|
|delete?(uri: string, predicates: DataSharePredicates, callback: AsyncCallback&lt;number&gt;): void|Deletes data from the database.|
For more details, see [DataShareExtensionAbility](../reference/apis/js-apis-application-DataShareExtensionAbility.md).
**Table 2** APIs of the data consumer
| API | Description |
| :----------------------------------------------------------- | :--------------------------------- |
| createDataShareHelper(context: Context, uri: string, callback: AsyncCallback&lt;DataShareHelper&gt;): void | Creates a **DataShareHelper** instance. |
| insert(uri: string, value: ValuesBucket, callback: AsyncCallback&lt;number&gt;): void | Inserts a single data record into the database. |
| update(uri: string, predicates: DataSharePredicates, value: ValuesBucket, callback: AsyncCallback&lt;number&gt;): void | Updates data in the database. |
| query(uri: string, predicates: DataSharePredicates, columns: Array&lt;string&gt;, callback: AsyncCallback&lt;DataShareResultSet&gt;): void | Queries data from the database. |
| delete(uri: string, predicates: DataSharePredicates, callback: AsyncCallback&lt;number&gt;): void | Deletes one or more data records from the database.|
For more details, see [DataShareHelper](../reference/apis/js-apis-data-dataShare.md).
## When to Use
**DataShare** can be divided into the following:
- Data provider: Implement functions of adding, deleting, modifying, and querying data, and opening files, and share data.
- Data consumer: Access the data provided by the provider using **DataShareHelper**.
Examples are given below.
### Data Provider Application Development (Only for System Applications)
1. Import the dependencies.
```ts
import Extension from '@ohos.application.DataShareExtensionAbility'
import rdb from '@ohos.data.rdb';
import fileIo from '@ohos.fileio'
import dataSharePredicates from '@ohos.data.dataSharePredicates'
```
2. Override **DataShareExtensionAbility** APIs based on actual requirements. For example, if the data provider provides only data query, override only the query() API.
3. Implement the data provider services. For example, implement data storage of the data provider by using a database, reading and writing files, or accessing the network.
```ts
let DB_NAME = "DB00.db";
let TBL_NAME = "TBL00";
let DDL_TBL_CREATE = "CREATE TABLE IF NOT EXISTS "
+ TBL_NAME
+ " (id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT, age INTEGER, isStudent BOOLEAN, Binary BINARY)";
let rdbStore;
let result;
export default class DataShareExtAbility extends Extension {
private rdbStore_;
// Override the onCreate() API.
onCreate(want, callback) {
result = this.context.cacheDir + '/datashare.txt'
// Create an RDB.
rdb.getRdbStore(this.context, {
name: DB_NAME
}, 1, function (err, data) {
rdbStore = data;
rdbStore.executeSql(DDL_TBL_CREATE, [], function (err) {
console.log('DataShareExtAbility onCreate, executeSql done err:' + JSON.stringify(err));
});
callback();
});
}
// Override the query() API.
query(uri, predicates, columns, callback) {
if (predicates == null || predicates == undefined) {
console.info('invalid predicates');
}
try {
rdbStore.query(TBL_NAME, predicates, columns, function (err, resultSet) {
if (resultSet != undefined) {
console.info('resultSet.rowCount: ' + resultSet.rowCount);
}
if (callback != undefined) {
callback(err, resultSet);
}
});
} catch (err) {
console.error('error' + err);
}
}
// Override other APIs as required.
// ...
};
```
4. Define **DataShareExtensionAbility** in **module.json5**.
| Field| Description |
| ------------ | ------------------------------------------------------------ |
| "name" | Ability name, corresponding to the **ExtensionAbility** class name derived from **Ability**. |
| "type" | Ability type. The value is **dataShare**, indicating the development is based on the **Datashare** template.|
| "uri" | URI used for communication. It is the unique identifier for the client to connect to the server. |
| "visible" | Whether it is visible to other applications. Communication with other applications is allowed only when the value is **true**.|
**module.json5 example**
```json
"extensionAbilities": [
{
"srcEntrance": "./ets/DataShareExtAbility/DataShareExtAbility.ts",
"name": "DataShareExtAbility",
"icon": "$media:icon",
"description": "$string:description_datashareextability",
"type": "dataShare",
"uri": "datashare://com.samples.datasharetest.DataShare",
"visible": true
}
]
```
### Data Consumer Application Development
1. Import basic dependencies.
```ts
import Ability from '@ohos.application.Ability'
import dataShare from '@ohos.data.dataShare'
import dataSharePredicates from '@ohos.data.dataSharePredicates'
```
2. Define the URI string for communicating with the data provider.
```ts
// Different from the URI defined in the module.json5 file, the URI passed in the parameter has an extra slash (/), because there is a DeviceID parameter between the second and the third slash (/).
let dseUri = ("datashare:///com.samples.datasharetest.DataShare");
```
2. Create a **DataShareHelper** instance.
```ts
let dsHelper;
let abilityContext;
export default class MainAbility extends Ability {
onWindowStageCreate(windowStage) {
abilityContext = this.context;
dataShare.createDataShareHelper(abilityContext, dseUri, (err,data)=>{
dsHelper = data;
});
}
}
```
3. Use the APIs provided by **DataShareHelper** to access the services provided by the provider, for example, adding, deleting, modifying, and querying data.
```ts
// Construct a piece of data.
var valuesBucket = {"name": "ZhangSan", "age": 21, "isStudent": false, "Binary": new Uint8Array([1,2,3])};
var updateBucket = {"name": "LiSi", "age": 18, "isStudent": true, "Binary": new Uint8Array([1,2,3])};
let da = new dataSharePredicates.DataSharePredicates();
var valArray =new Array("*");
let people = new Array(
{"name": "LiSi", "age": 41, "Binary": ar},
{"name": "WangWu", "age": 21, "Binary": arr},
{"name": "ZhaoLiu", "age": 61, "Binary": arr});
// Insert a piece of data.
dsHelper.insert(dseUri, valuesBucket, (err,data) => {
console.log("dsHelper insert result: " + data);
});
// Delete the specified data.
dsHelper.delete(dseUri, da, (err,data) => {
console.log("dsHelper delete result: " + data);
});
// Update data.
dsHelper.update(dseUri, da, updateBucket, (err,data) => {
console.log("dsHelper update result: " + data);
});
// Query data.
dsHelper.query(dseUri, da, valArray, (err,data) => {
console.log("dsHelper query result: " + data);
});
```

# DataShare Overview
## Introduction
The **DataShare** module allows an application to manage its own data and share data with other applications. Currently, data can be shared only between the applications on the same device.
**DataShare** is used in application scenarios, such as contacts, short message service (SMS), and media gallery. However, not all data, such as accounts and passwords, can be accessed by other applications. Some data, such as SMS messages, can only be queried by other applications. **DataShare** provides a secure data sharing mechanism for applications.
The data provider can directly use the **DataShare** framework to share data with other applications without complex encapsulation. The data consumer only needs to learn and use a set of interfaces because the data access mode does not vary with the data provisioning mode. This greatly reduces the learning time and development difficulty.
## Basic Concepts
Before you get started, familiarize yourself with the following concepts:
- Data provider
An application that provides data and implements related services. It is also called a producer or server.
- Data consumer
An application that accesses the data or services provided by a data provider. It is also called a client.
- Value bucket (**ValuesBucket**)
One or more data records stored in the form of key-value (KV) pairs. The keys are of the string type. The values can be of the number, string, Boolean, or Unit8Array type.
- Result set
A collection of query results. Flexible data access modes are provided for users to obtain data.
- Predicate
Conditions specified for updating, deleting, or querying data in the database.
## Working Principles
**Figure 1** DataShare mechanism
![](figures/en_DataShare.png)
- The **DataShareExtAbility** module, as the data provider, implements data sharing between applications.
- The **DataShareHelper** module, as the data consumer, provides interfaces for accessing data, including adding, deleting, modifying, and querying data.
- The data consumer communicates with the data provider using inter-process communication (IPC). The data provider can be implemented through a database or other data storage.
- The **ResultSet** module is implemented through shared memory. Share memory stores the result sets, and interfaces are provided to traverse result sets.
## Constraints
- **DataShare** is subject to the limitations on the database used by the data provider. For example, the supported data models, length of the keys and values, and maximum number of databases that can be accessed at a time by each application vary with the database in use.
- The payloads of **ValuesBucket**, predicates, and result sets are restricted by IPC.

11. Unsubscribe from the status changes of the distributed data object.
You can specify the callback to unregister. If you do not specify the callback, this API unregisters all callbacks of this distributed data object.
The sample code is as follows:
```js
```js
// Unregister the specified status change callback.
local_object.off("status", this.statusCallback);
// Unregister all status change callbacks.
local_object.off("status");
```
```
12. Remove a distributed data object from the synchronization network. Data changes on the local object will not be synchronized to the removed distributed data object.
The sample code is as follows:
```js
local_object.setSessionId("");
```
## Development Example
The following example is provided for you to better understand the development of distributed data objects:
- [Distributed Notepad](https://gitee.com/openharmony/distributeddatamgr_objectstore/tree/master/samples/distributedNotepad)
When an event of the Notepad app occurs on a device, such as a note is added, the title or content of a note is changed, or the event list is cleared, the change will be synchronized to other devices in the trusted network.
