What is the difference between hadoop and google analytics

Question

I am new to Hadoop and everything around big data. while my research about social media data integration with big data I found a lot about Hadoop.

But I know there is google analytics too if I want to observe social media and get some statistics.

So, why are so many companies using Hadoop instead of google analytics? What is the difference between those two?

Answer 1

I will try and answer this as good as possible, as it's a strange question :)

The reason I say it's strange is they are not really related and trying to find a co-relation to compare is tricky.

Google Analytics- Typically used to track web behavior. Provides a nice UI and is typically digestible by non-technical people (marketing etc) to find insights.

Hadoop - Hadoop at its core is a file system (think of a very large hard-drive), it stores data in a distributed fashion (on n number of servers). It claims to fame is map/reduce and the plethora of applications like Hive or Pig to analyze data sitting in Hadoop.

A better comparison to the products you mentioned would be something like:

1. Why would I use Google Analytics vs Comscore? (web analytics)
2. Why would I use Hadoop vs Postgres? (data storage and data analyses)
