This document discusses big data, where most data comes from in recent years, and how tools like Hadoop can help manage large and diverse datasets. It notes that big data is defined by the 3Vs of volume, variety and velocity, and that 90% of today's data was generated in just the past 3 years. Managing big data can provide benefits like cost reduction, faster decision making and new product development, but also poses challenges regarding talent, security and the difficulty of using tools like Hadoop.

3. • Database which is large and
complex.
• Data can be structures and
unstructured.
• It is stated that almost 90%
of today's data has been
generated in the past 3
years.

4. From Where The Data Comes From

5. Do We Lead With Big Data?
Through the 3 V’s of Big Data
1.Volume
2.Variety
3.Velocity

6. •Diversity of
vendors
•Sql on Hadoop
•Lack of talent
•Security
Hadoop is hard

9. WHY IT IS SO IMPORTANT?
1) Cost Reduction
2) Time Reductions
3) New Product Development
And Optimized Offerings
4) Smart Decision Making

10. Here we discussed about the big data ,where
the data comes from and how we can manage
the data .
The tools of big data help us to manage the
large amount of data. And the tools have their
pros and cons that where they have to be
used. There are various technology that
manages the huge amount of data .We use 90%
of data in a day that was generated last 3
years . In next few year the data is 3 times
more than today’s data.
