About this knowledge path

For all of XML's good points—flexibility and adaptability, to name just two—it is a verbose meta-language. The very size of XML files can be an obstacle to efficient interchange of and access to data, especially when sending files to web services. Data compression plays a significant role in optimizing XML. This knowledge path introduces both the theoretical and the practical details of data compression. This knowledge path is designed for those who are new to XML and application development.

Activities in this path

  1. Learn the basics of data compression
  2. Apply data compression techniques to XML
  3. Consider different compression tools
  4. Learn more about data compression and XML by studying product-specific tips
  5. Put this new information in a larger context; consider getting certified in XML and related technologies
