DataSource is SmartGWT's way of creating a standard interface for populating widgets with data from the server.

You don't NEED DataSources, but they provide a relatively simple method for putting data into your widgets and having them display that data.

The thing that got me for a while was figuring out that each widget depends upon certain fields to be inside the DataSource. Once you get the fields named properly, everything starts working automagically.

I suggest you try to understand how you can use a DataSource to get/update your data instead of trying to find a way to do so without a DataSource. Why? You will find the feature makes that far easier and much more feature-rich. A DataSource is a KEY SmartGWT feature and you will regret not understanding them.
