# Access Multiple DBs in CloudCode Tasks

By default, a `DB` object is exposed when the CloudCode task is invoked.

### Accessing Other Deployments

To access a different deployment within the same app or a different app, a new DB object can be created:

```javascript
// Same app, different deployment
const otherDB = await CloudCode.createDB('https://{app-deployment-id}.backend.{region-code}.journeyapps.com/', '{backend-deployment-id}', {username: '{backend-deployment-id}', password: 'mypassword'});
const otherDB = await CloudCode.createDB('https://{app-deployment-id}.backend.{region-code}.journeyapps.com/', '{backend-deployment-id}', {token: 'mytoken'});
// Example
const otherDB = await CloudCode.createDB('https://62d541f4156bc4dd685318da.backend.us.journeyapps.com/', '62d541ff9f54b7000706c585', {token: 'mytoken'});

// Different app
const otherDB = await CloudCode.createRemoteDB('https://{app-deployment-id}.backend.{region-code}.journeyapps.com/', '{backend-deployment-id}', {username: '{backend-deployment-id}', password: 'mypassword'});
const otherDB = await CloudCode.createRemoteDB('https://{app-deployment-id}.backend.{region-code}.journeyapps.com/', '{backend-deployment-id}', {token: 'mytoken'});
// Example
const otherDB = await CloudCode.createRemoteDB('https://62d541f4156bc4dd685318da.backend.us.journeyapps.com/', '62d541ff9f54b7000706c585', {token: 'mytoken'});
```

<Warning title={"Accessing other apps with different data models"}>

If you try to use this to access another app's DB, make sure to use `createRemoteDB` and not `createDB`. Otherwise, you'll get errors like `TypeError: Cannot read property 'where' of undefined`

</Warning>

<Info title={"Use environment variables to store credentials"}>

It is best practice to use masked environment variables to store and reference passwords or tokens when using `createDB`. [Read more about environment variables here](/docs/cloudcode/advanced-cloudcode-topics/deployment-environment-variables/).

</Info>

### Alternative: Accessing APIv4 directly

APIv4 can be accessed directly using `fetch`. To avoid hardcoding APIv4 credentials, the details of the current deployment are exposed on the task:

```javascript
async function downloadUserData(backend) {
 		let response = await fetch(backend.url + '/objects/user.json', {
        headers: {
            Authorization: backend.authorization
        }
    });
    if(!response.ok) {
        throw new Error(response.statusText);
    }
    let data = await response.json();
    return data.objects;
}

async function downloadSchema(backend) {
    let response = await fetch(backend.url + '/datamodel.json', {
        headers: {
            Authorization: backend.authorization
        }
    });
    if(!response.ok) {
        throw new Error(response.statusText);
    }
    return await response.text();
}

export async function run() {
    let users = await downloadUserData(this.backend);
  	console.log('Users', users);

    let schema = await downloadSchema(this.backend);
    console.log('Schema', schema);
}
```
