Bit Data is defined as "extremely large data sets that may be analyzed computationally to reveal patterns, trends, and associations, especially relating to human behavior and interactions."
Hadoop is simply a file system for storing and processing large amounts of data (big data). It allows you to distribute processes and data across tens, hundreds, or thousands of computers.
NoSQL is simply "Not Only SQL"--it's a document-based, non-relational database engine. MongoDB is an example of a NoSQL database. SQL Server, Oracle, MySQL are examples of relational databases.
How do they all fit together? Big data is loaded into a NoSQL database where the data is stored and processed using Hadoop. That's a very high level of looking at it. I hope it makes sense.

What is Big data??
Every day,2.5 quintillion bytes of data comes from everywhere: sensors used to gather climate information, posts to social media sites, digital pictures and videos, purchase transaction records, and cell phone GPS signals to name a few. This data is big data.
What is hadoop?
Hadoop is a free, Java-based programming framework that supports the processing of large data sets in a distributed computing environment. It is part of the Apache project sponsored by the Apache Software Foundation.
What is nosql??
A NoSQL (originally referring to "non SQL" or "non relational") database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases.

You may need to be careful deleting cells, as this can mess with calculations further down or across. The alignment of reference cells may no longer be in correct place so any calculations may error out as data cannot be found, or your result may be different as another value is entered in the final result. If you have graphs etc in this file they may not work. Try saving the file to a back up location and then try editing one of the files.

All terms you are asking for are related to Database management.Nowadays all the activities are becoming database-centric and the companies have to manage a huge pool of data.The concept is Big data and the process by which the companies manages the data effectively is called hadoop. there are more process like mongoDB but Hadoop is more effective.
