# Query Data

Once the data is loaded into SingleStore, it can be queried for both analytical and transactional purposes.

SingleStore supports the following query-related features:

* The [SELECT](https://docs.singlestore.com/db/v9.1/query-data/select.md) command retrieves data from a database. From this basic SQL command, you can utilize more advanced query concepts such as [performing upserts](https://docs.singlestore.com/db/v9.1/query-data/advanced-query-topics/performing-upserts.md) and creating [common table expressions](https://docs.singlestore.com/db/v9.1/query-data/advanced-query-topics/with-common-table-expressions.md).
* The [INSERT](https://docs.singlestore.com/db/v9.1/reference/sql-reference/data-manipulation-language-dml/insert.md), [DELETE](https://docs.singlestore.com/db/v9.1/reference/sql-reference/data-manipulation-language-dml/delete.md), and [UPDATE](https://docs.singlestore.com/db/v9.1/reference/sql-reference/data-manipulation-language-dml/update.md) commands manipulate data within a database and can utilize querying elements such as `INSERT... SELECT`, `DELETE` with filters, join, and subqueries, or `UPDATE` with filters, joins, and subqueries.
* The [EXPLAIN](https://docs.singlestore.com/db/v9.1/reference/sql-reference/data-manipulation-language-dml/explain.md), [EXPLAIN UI](https://docs.singlestore.com/db/v9.1/reference/sql-reference/data-manipulation-language-dml/explain.md), [PROFILE](https://docs.singlestore.com/db/v9.1/reference/sql-reference/data-manipulation-language-dml/profile.md), and [SHOW PROFILE UI](https://docs.singlestore.com/db/v9.1/reference/sql-reference/data-manipulation-language-dml/profile.md) features can help you understand the performance of your queries. These features allow you to analyze query plans and gather execution statistics, which can aid in identifying bottlenecks and optimizing your database queries. 
* SingleStore supports [integration ](https://docs.singlestore.com/db/v9.1/query-data/connect-with-analytics-and-bi-tools.md) with a wide range of third-party data analytics and business intelligence software such as Dremio, Looker, MicroStrategy, Power BI, Sisense, Tableau, and Tibco Spotfire.
