Package Specification

Provides a query language - subset of SQL language.
Clients who wish to pass a parsed query to the Connector Framework, must implement this package objects. Then the query needs to be build by this package objects. An IOperation object should be passed to IExecutrion.execute(IOperation). IExecutrion object can be created from IConnection.newExecution()
