The Definitive Plain-English Guide to Big Data for Business and Technology Professionals
Big Data Fundamentals provides a pragmatic, no-nonsense introduction to Big Data. Best-selling IT author Thomas Erl and his team clearly explain key Big Data concepts, theory and terminology, as well as fundamental technologies and techniques. All coverage is supported with case study examples and numerous simple diagrams.
The authors begin by explaining how Big Data can propel an organization forward by solving a spectrum of previously intractable business problems. Next, they demystify key analysis techniques and technologies and show how a Big Data solution environment can be built and integrated to offer competitive advantages.

Understanding the business motivations and drivers behind Big Data adoption, from operational improvements through innovation
Planning strategic, business-driven Big Data initiatives
Addressing considerations such as data management, governance, and security
Recognizing the 5 “V” characteristics of datasets in Big Data environments: volume, velocity, variety, veracity, and value
Clarifying Big Data’s relationships with OLTP, OLAP, ETL, data warehouses, and data marts
Working with Big Data in structured, unstructured, semi-structured, and metadata formats
Increasing value by integrating Big Data resources with corporate performance monitoring
Understanding how Big Data leverages distributed and parallel processing
Using NoSQL and other technologies to meet Big Data’s distinct data processing requirements
Leveraging statistical approaches of quantitative and qualitative analysis
Applying computational analysis methods, including machine learning
