I am extremely happy with the course on "Learn By Example: Hadoop, MapReduce for Big Data problems". It gives an excellent overview of hadoop and mapreduce concepts. It is a must take for all who want to build their career in Bigdata.
Unanth is redefining the Online Learning experience. I heard about this from a friend and took few courses on this platform and liked the way they selected their courses. I am impressed with the quality of the courses on Unanth.
I must say "Amazing". The course on Microsoft Excel has all the information that is required for a data analysis job. From clear structure, and contents on the course backed by support from Unanth team makes it a great learning experience.
