# Kendo UI for jQuery DataSource Overview

The [Kendo UI DataSource component](https://demos.telerik.com/kendo-ui/datasource/index) plays a central role in all web applications built with Kendo UI for jQuery.

The DataSource is an abstraction for using local data (arrays of JavaScript objects) or remote data (web services returning JSON, JSONP, [oData](http://www.odata.org/), or XML). The DataSource supports CRUD (Create, Read, Update, Destroy) data operations and provides both client-side and server-side support for sorting, paging, filtering, grouping, and aggregates.

> A known limitation is the inability to name a DataSource field "data".
