New release

[Rick]

Hi

A new release of Data Management will appear in a day or so in the Kindle shop.

The main changes are:

1. Greater coverage of dplyr in the Introduction to R. Dplyr is very popular with R coders.
   
2. Retitling of the chapter on Hadoop and MapReduce to Cluster Computing and the replacement of the material on MapReduce with Apache Spark. Spark is less complex than MapReduce for cluster computing and works well with dplyr. 
   

I am teaching a data management class this semester, and I will make minor updates in the text and slides as I prepare for class.

I am also teaching an advanced data management class based on R.  See http://people.terry.uga.edu/rwatson/mist5730/

All the best

Rick
