# 启动DataAbility


启动DataAbility会获取一个工具接口类对象（DataAbilityHelper）。启动DataAbility的示例代码如下：

```ts
import featureAbility from '@ohos.ability.featureAbility';
import ability from '@ohos.ability.ability';

let uri: string = 'dataability:///com.samples.famodelabilitydevelop.DataAbility';
let DAHelper: ability.DataAbilityHelper = featureAbility.acquireDataAbilityHelper(uri);
```
