This presentation discusses big data, including what it is, its key characteristics, big data science, and big data analytics. Big data refers to large, unstructured data sets that come from various sources like social media, flight recorders, etc. It is characterized by its volume, velocity, variety, and value. Big data science works to categorize and structure this unstructured data to make it useful by applying big data analytics techniques like analyzing massive amounts of data, categorizing it, and extracting meaningful information. The presentation wishes all attendees a happy and prosperous day.

2. What Is Big Data ?
 Big data is a unstructured data mean in this form we
find data which is un meaningful or we can say un
useful form of data.
 In this form of data we are seeing data have in
terabytes or in petabytes.
 Big data can be have in any form.
 This is a unmeaning full information which has
produced from any where. (Facebook, twitter, Flight
data recorder and etc.)

3. The dimension or characteristics of big data.
 VOLUME (Data size terabytes, petabytes etc.)
 VELOCITY (Speed to increasing the size of data)
 VALUE (What is usability of that unstructured data)
 VARITY (Format of data mean txt, audio, video,
number or data)

4. Big Data Science
 Big data science provide us a method to categorized
all unstructured data.
 Big data science make all unstructured data in a
useful data form.
 Making unstructured data in a useful, categorised
and structured form called Big data analytics or big
data science.

5. What have in Big data analytics.
 Analysing massive amount of data.
 Categorising in a specific structured form.
 Getting a useful information.
 Process all unusual data.
 Appropriate information.

6. A HAPPY AND PROSPEROUS DAY
TO ALL FRIENDS.
