Orchestrating an analytic workflow in the Teradata Unified Data Architecture

Overview

This article describes how to combine exploratory analytics and operational analytics within the Teradata Unified Data architecture (UDA). The UDA is a logical and physical architecture that adds a data lake platform to complement the Teradata Integrated Data Warehouse. In the Teradata advocated solution, the data lake platform can either be Hadoop or a Teradata Integrated Big Data Platform optimized for storage and processing of big data. Query Grid is an orchestration mechanism that supports seamless integration of multiple types of purpose built analytic engines within the UDA.
