ViewModels

We should support some form of ViewModel. A very simple implementation could depend explicitly on MongoDB. I'm struggling to come up with the exact js API, but the features would be:

• readonly
• aggregate data from multiple data sources based on model relations
• focus on read performance (and local caching config?)
• able to be created without DBAs / sql / etc
• avoid joins and slow SQL operations
• query the aggregated data

A real use case for this is illustrated in the access control example app. The client currently makes a single http request and the server calculates the account balance on demand.

With a ViewModel, the app would make the request to the ViewModel which would be backed by an aggregation (including caluclations) of all the transaction data.

Sounds like a good idea but I would suggest a slightly different name to avoid confusion with front-end views. Maybe DataViewModel or something.

Maybe DataViewModel or something.

How about ClientModels, MobileModels, FrontModels?
