Every day, all around the world, programmers have to recycle legacy data, translate from one vendor’s proprietary format into another’s, check that configuration files are internally consistent, and search through web logs to see how many people have downloaded the latest release of their product.

This kind of data crunching, may not be glamorous, but knowing how to do it efficiently is essential to being a good programmer. This book describes the most useful data crunching techniques, explains when you should use them, and shows how they will make your life easier. Along the way, it will introduce you to some handy, but under-used, features of Java, Python, and other languages. It will also show you how to test data crunching programs, and how data crunching fits into the larger software development picture.

Data Crunching covers areas of most interest to working programmers:

  • Using Plain Text Files
  • Learning Regular Expression syntax
  • Parsing XML using SAX, DOM, and XSLT
  • Encoding data in binary files
  • Handling relational databases using SQL
