Big data technologies

Among the big data technologies you'll need to know are the Apache Software Foundations' Java-based Hadoop programming framework that can run applications on systems with thousands of nodes; and the MapReduce software framework, which consists of a Map function that distributes work to different nodes and a Reduce function that gathers results and resolves them into a single value. Also gaining more attention is the Apache Hive data warehousing component, which offers a query language called HiveQL that translates SQL-like queries into MapReduce jobs automatically. Finally, learn how Microsoft is trying to get in on the Hadoop action with its own SQL Server-Hadoop connectors.
