Big Data
Big Data is a collection of very large data sets that may be analyzed computationally to reveal patterns, trends, and associations,also especially relating to human behavior and also interactions. And Big data is a word for data sets that are so huge otherwise complex that traditional data processing application software is inadequate to deal with them. Challenges include capture, storage, analysis, data cu-ration, search, sharing, transfer, visualization, querying, as well as also updating and information privacy. The term “big data” often refers simply to the use of predictive analytic, consumer deeds analytic, otherwise certain other advanced data analytic method that extracts value from data, and seldom to a particular size of data set.
What is Big Data
Big data really means a big data. It is a collection of huge data-sets that cannot be processed via traditional computing techniques. Big data is not merely a data; rather it has become a complete subject so then, which involves various tools, techniques, as well as frameworks.
What is Big Data Management
Big data management is the organization, administration, and also governance of large volumes of both structured as well as unstructured data. Consequently the objective of big data management is to ensure a high level of data quality as well as accessibility for business intelligence as well as big data analytic applications. Corporations, government agencies, in addition to other organizations use big data management strategies to help them contend with also fast-growing pools of data, typically involving many terabytes or even petabytes of information saved in a variety of file formats. As a result, efficient big data management helps companies locate precious information in large sets of unstructured data as well as also semi-structured data from a variety of sources, including call detail records, system logs, as well as also social media sites.
Characteristics of Big Data
thus there are four types of characteristics are given below
- 1st is Volume
- 2nd is Velocity
- 3rd is Variability
- 4th is Veracity
What Comes Under Big Data
- Black Box Data:
It is a part of helicopter, airplanes, and also jets, etc. It captures voices of the air travel crew, recordings of microphones and earphones, as well as the performance and information of the aircraft.
- Social Media Data:
Social media likewise Facebook as well as Twitter hold data otherwise information as well as the views posted by millions of people across the globe.
- Stock Exchange Data:
The stock exchange data holds data in addition to information about the ‘buy’ as well as also ‘sell’ decisions made on a share of different companies made by the customers.
- Power Grid Data:
This also comes under the big data.The power grid data holds data as well as information consumed by an exacting node with respect to a base station.
- Transport Data:
Transport data includes model, capacity, distance as well as availability of a vehicle.
- Search Engine Data:
Search engines recover lots of data from different databases.
Consequently all these are the part of big data and as a result Big data is very useful in today’s life.
Consequently the data will be of three types
The three types of data are
- Structured data: Relational data.
- Semi-Structured data: XML data.
- Unstructured data: Word, PDF, Text, Media Logs.
