Wishing all the readers of my blog a happy and prosperous New Year 2015. In this year one can see how the big data technologies mature or adopted within organizations. What happens to predictive analytics/machine learning type of technologies, how well they come into mainstream organizations. How is the role of data scientists going to evolve, along side with the traditional data warehouse technologies. There is a very good introduction course on The Data Scientist's toolbox that covers the foundation required for Data analysis and Data Scientists role.www.coursera.org.
