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; providing a user interface to the services layer, the user interface configured to define an analytic solution as an executable sequence of two or more of the models associated with different instances of the analytic engines, wherein the services layer provides representational state transfer web services that support direct invocation by an enterprise application and an administrative console that provides the user interface including a graphic sequence editor to build the executable sequence; registering, deploying, executing, and monitoring the models through the services layer; and storing registered data in a metadata repository that is accessible through one of: a file system and a database system.
