Big data is all the rage. So you better buckle down and learn the
ins and outs of Hadoop, Hive, Pig, Solr, Spark, and all the other
Apache tools people say are absolutely required to take advantage
of the revolution. Right? Maybe not. As Neil Dunlop, chair of the
Computer Science Department at Berkeley City College in California
demonstrates in Big Data for the Little Guy , it turns out that a
data analyst or tech-savvy IT or business manager armed with the
latest versions of Excel and Power BI can import data into them and
perform valuable, professional analyses of a company's Big Data
assets.§§While Big Data for the Little Guy: Big Data Processing and
Analysis Using Power BI in Excel 2013 covers prominent tools such
as Hadoop and the NoSQL database Cassandra, it recognizes that most
small and medium-sized businesses don't have the Big Data
processing needs of a Netflix, Target, or Facebook. Instead, it
shows how to import data and use the self-service analytics
available in Excel with Power BI. As you'll see through the book's
numerous case examples, these tools - which you already know how to
use - can perform many of the same functions as the higher-end
Apache tools many people believe are required to carry out in Big
Data projects.§§To set the business context, veteran
programmer/developer, teacher, and Excel/Power BI expert Neil
Dunlop starts by reviewing the importance of analyzing data before
making important business decisions and then determining when
higher-end tools such as Hadoop and Cassandra are necessary. He
then shows in great depth how small and medium-sized businesses can
meet most of their data analysis needs using Excel with Power
BI.§Through instruction, insight, advice, and case studies, Big
Data for the Little Guy will show you how to:§§Import and mash up
data from web pages, SQL and NoSQL databases, the Azure Marketplace
and other sources.§Tap into the analytical power of PivotTables and
PivotCharts and develop relational data models to track trends and
make predictions based on a wide range of data.§Understand basic
statistics and use Excel with PowerBI to do sophisticated
statistical analysis - including identifying trends and
correlations.§Use SQL within Excel to do sophisticated queries
across multiple tables, including NoSQL databases.§Create complex
formulas to solve real-world business problems using Data Analysis
Expressions (DAX). §Along the way, you'll learn how to present the
data using visual tools such as slicers, dashboards that summarize
real-time results in relation to goals, data-driven maps, and OLAP
cubes for multidimensional analysis. Through the book's emphasis on
real-world cases and examples, you'll understand how to meet most
of your big data analysis and decision needs using Excel and Power
BI. That will save you time, money, and effort while providing the
answers you need to critical business questions - faster and more
accurately than ever.§§
