Query2 must have the facility to allow query execution and retrieval of results from hetergeneous backend.It must provide a framework (Storage processor framework) which provide the facility to let allow the backend plug-in their own code.

The Query storage processors for a respective backend must provide the following facilities.

(a) Query execution and results retrieval.
(b) Query mapping from Query2 to native Query language or any query interpretation.
(c) Conversion of native results to Query2 result data structure.

Query mapping or transformation of Query can be helped if we have an EMF model of the Interal Query BQL AST.Already a bug opened for this
https://bugs.eclipse.org/bugs/show_bug.cgi?id=353092

Once we get the model it will make the storage processor framework more robust and more flexible.
