# Data Stores

## Usage

{% hint style="success" %}
Use Data Stores to easily make variables persistent and retrievable.
{% endhint %}

Data Stores are used primarily in [Message Scripts](/unifi/3.0/configuration/message-scripts.md) and [Poll Processor](/unifi/3.0/polling/poll-processors.md) scripts when you want to get and set functional data that is relevent to the integration but does not belong on the target record.

This is particularly handy in a uni-directional integration where polling the remote system is necessary. You can store data such as:

* The last time a request was made
* Identifiers that have been seen before
* Watermarks

## Example

### Storing Strings

Use `getData` and `setData` to work with simple string-like data.

```javascript
// Store the current log count
var log_count = bond.getData('log_count');
bond.setData('log_count', parseInt(log_count, 10) + 1)
```

### Storing Objects

You can also work with objects just as easily by using `getDataObject` and `setDataObject`. These functions automatically take care of encoding the object for database storage and decoding it for JavaScript usage again.

```javascript
// Store the logs that have been seen
var logs_seen = bond.getDataObject('logs_seen'); // [1375, 1399, 1748]
logs_seen.push(2140);
bond.setDataObject('logs_seen', logs_seen);
```
