Framework for building Rich Internet Applications

I have been building web applications for the last 10 years. I have built a huge list of enterprise web applications in that time period. To make webwiki a success, there needs to be a rapid framework for building and deploying applications.

Such a framework will need to impose the following restrictions:

• DB Schema simplification: The database schema needs to be abstracted out to such an extent that developers feel they are in control of the schema. This schema should allow for storage of different application objects
  
• Web Service Enabled: Whatever transactions the developers write should automatically be exposed as a web service

By having automatic exposure as a web service, it allows for lot of operational flexibility as 'similar' web services can be clustered.
