Hi,
I imagine any of you would be able to explain this to me.
If I understand correctly, Hadoop is a type of database that handles unstructured data.
How does Map Reduce play into it's use?

Can you give a simple example?

thanks,
Paul

Hadoop is NOT a database. It is framework to process data.

Hadoop is implementation of MapReduce paradigm.

Read about MapReduce paper by google for intro to MapReduce

Look for Wordcount example from Google site for an example.
