Overview of this book

Organizations are leveraging the use of data and analytics to gain a competitive advantage over their opposition. Therefore, organizations are quickly becoming more and more data driven. With the advent of Big Data, existing Data Warehousing and Business Intelligence solutions are becoming obsolete, and a requisite for new agile platforms consisting of all the aspects of Big Data has become inevitable. From loading/integrating data to presenting analytical visualizations and reports, the new Big Data platforms like Greenplum do it all. It is now the mindset of the user that requires a tuning to put the solutions to work. "Getting Started with Greenplum for Big Data Analytics" is a practical, hands-on guide to learning and implementing Big Data Analytics using the Greenplum Integrated Analytics Platform. From processing structured and unstructured data to presenting the results/insights to key business stakeholders, this book explains it all. "Getting Started with Greenplum for Big Data Analytics" discusses the key characteristics of Big Data and its impact on current Data Warehousing platforms. It will take you through the standard Data Science project lifecycle and will lay down the key requirements for an integrated analytics platform. It then explores the various software and appliance components of Greenplum and discusses the relevance of each component at every level in the Data Science lifecycle. You will also learn Big Data architectural patterns and recap some key advanced analytics techniques in detail. The book will also take a look at programming with R and integration with Greenplum for implementing analytics. Additionally, you will explore MADlib and advanced SQL techniques in Greenplum for analytics. This book also elaborates on the physical architecture aspects of Greenplum with guidance on handling high-availability, back-up, and recovery.

Greenplum Database

Greenplum Database is a collection of several PostgreSQL database instances acting as one interconnected database using highly-tuned optimizer. It is an MPP shared nothing database that involves more than one node to cooperate to execute one operation. Every node has its own disk, memory, and operating system. Greenplum uses this high-performance system architecture to distribute the load of large volume of data warehouses and is able to use all of the system resources in parallel to process a query.

Greenplum Database is based on PostgreSQL 8.2.15 and is very similar with respect to SQL support, features, configuration options, and so on (additionally, features from PostsgreSQL 8.3 and 9.0 have been included). The internals of PostgreSQL have been modified or supplemented to support the parallel structure of Greenplum DB. The interconnect component enables...
