This application is based on an OData version of the traditional Northwind database.

The OData source was created using the Microsoft Entity Framework over a SQL Server Compact Edition (sdf) file.

The ODataCollectionView class in the wijmo.odata.js module extends the CollectionView class to connect to OData services. In addition to getting and setting the data, it provides an easy way to specify whether filtering, sorting, and paging should be performed on the server or on the client.

Note that the grids have several data-mapped columns. For example, the orders grid shows the name of the employee rather than the ID. If you change an employee's name, the orders grid will be updated automatically.
