Gain the basics of Ruby's map reduce and select functions and discover how to use them to
solve data-processing problems. This compact hands-on book explains how you can encode certain
complex programs in 10 lines of Ruby code an astonishingly small number. You will walk through
problems and solutions which are effective because they use map reduce and select. As you
read Ruby Data Processing type in the code run the code and ponder the results. Tweak the
code to test the code and see how the results change. After reading this book you will have a
deeper understanding of how to break data-processing problems into processing stages each of
which is understandable debuggable and composable and how to combine the stages to solve
your data-processing problem. As a result your Ruby coding will become more efficient and your
programs will be more elegant and robust. What You Will Learn Discover Ruby data processing and
how to do it using the map reduce and select functions Develop complex solutions including
debugging randomizing sorting grouping and more Reverse engineer complex data-processing
solutions Who This Book Is For Those who have at least some prior experience programming in
Ruby and who have a background and interest in data analysis and processing using Ruby.
