1. A computer-implemented method for analytic solution integration, the method comprising: establishing an engine abstraction layer configured to interface with a plurality of analytic engines associated with a plurality of models; interfacing a services layer with the engine abstraction layer to provide a communication interface to invoke the analytic engines associated with the models; and providing a user interface to the services layer, the user interface configured to define an analytic solution as an executable sequence of one or more of the models.
