# Getting started with Query

Yandex Query enables both [analytical processing](../concepts/batch-processing.md) of data stored in [Yandex Object Storage](../../storage/index.md) and real-time [streaming processing](../concepts/stream-processing.md) from [Yandex Data Streams](../../data-streams/index.md). Built around the concept of [unified streaming and analytical computing](../concepts/unified-processing.md), Query allows you to process both streaming and analytical data with a single query.

Query uses [YQL](https://ydb.tech/docs/en//yql/reference/syntax/), an SQL dialect, to run queries.

To learn about Query features, follow these guides:

* [Analytical processing of Yandex Object Storage data](batch-example.md).
* [Yandex Data Streams streaming data processing](streaming-example.md).
* [Unified streaming and batch data analysis](unified-example.md).
