The wijmo.data module works as a separate layer on top of your data source by creating a service-specific data view. The view presents a subset of the information contained in the referenced database based on the filtering applied to the data view. This allows you to take care of filtering, sorting, and grouping without having to manipulate or change the underlying data. wijmo.data is designed to work with remote data sources like AJAX and OData, with JavaScript libraries like Breeze.js and knockout.js, or with a local array.

Data allows you to do all of the following.

• Connect to both local arrays and remote data sources.
• Bind widgets such as wijgrid to these data sources with little code.
• Support server-side filtering and paging with little or no code.
• Apply JavaScript functions to reshape data, reducing code and making it declarative.

The wijmo.data module is available in v3. If you are running v2.3.x, it is not included. You can download v3 here: Downloads Page. The Data module replaces the DataSource module, which is deprecated as of version 3.2013.1. In version 3 or higher, please use the Data module instead.
