We created a demo, http://demo.snaplogic.org/griddemo.html of the data mashup displayed in the Dojo Grid that uses a large data set and manipulates it entirely via SnapLogic framework. Data residing on the server or multiple servers is fed into SnapLogic's easy-to-create - either in GUI designer or Python - Pipelines that allow various manipulations and transformations (filtering, sorting, joining, etc.) and expose the results via RESTful interface.

The URIs of the Pipelines are fed to Dojo Grid via SnapLogic's Dojo dataStore. In this demo data filtering by State on the original, large dataset and then by Zip on the resulting set is done on the server, and the client-side javascript is limited to implementing the actual on-click mashup with Google Maps. The flexibility and interoperability of SnapLogic Pipelines makes creating and manipulating data feeds from many different original sources to be displayed in Dojo Grid a very attractive proposition.
