One implementation provides a computer system that integrates software applications with analytical software applications. In this implementation, the computer system is programmed to receive a request from a software application to execute an analytical task, such as a prediction task or a key performance indicator (KPI) lookup task. The request includes a task name and input information. The computer system then uses the task name to identify an analytical engine and a data store, and invokes an analytical software application in the analytical engine to execute the analytical task. The analytical task is executed using the identified data store and the received input information. The computer system receives task output from the invoked analytical software application, the task output including output information generated during execution of the analytical task. The computer system then sends the output information to the software application that made the request.
