What is BigData?

BigData is really a big data, when you do not have sufficient space to store a data that's where the problem arise. For instance, if you have 8GB of SD Card & you have utilized 7.5GB already, now you cannot add on 650MB of data into that right?, yes.. 

So there is no definite size for BigData!..

We have traditional database system to store the data that are structured, ex(rows & columns, some specific format). But now adays organizations are more concerned about their customers/clients/investors & want to improvise their business. In order to meet that, they need to analyse all forms of data & make a decision. 

Types of Data :
> Structured -- Database 
> Semi-Structured - XML document
> Unstructured  - Images, Videos, Text, PDF , Word Document & so on..

We might be clear with Structured / Semi-Structured &  have seen it before, but why do they want to analyse Unstructured?..

For Instance :

As soon as you click on some link in web, there are huge amount of data that are getting logged/generated behind the scenes about users, using which analysis can be done & find what kind of product/information that customer is looking into & reach customer accordingly.

By analysing images/videos, pattern matching can be done...

Well, am clear with everything but what Hadoop is doing here?-- Should be your next question?

Keep watching that in next post..
