The Case for Multi-Engine Data Analytics

As big data analytics have become an important driver for ICT development, a large variety of approaches that apply these advanced technologies on a wide spectrum of applications has been introduced. In this paper we argue on the need of a multi-engine environment that will exploit the largely different models, cost and quality of the existing analytics engines. Such an environment further requires an intelligent management system for orchestrating and coordinating complex analytics tasks over the different available engines. After summarizing some of the current approaches in data analytics, we outline the structure of our envisioned Multi-Engine Management System and present some of the corresponding research directions in its design and development.
