What are the characteristics of big data
This article mainly shows you "what are the characteristics of big data". The content is simple and clear. I hope it can help you solve your doubts. Next, let the editor lead you to study and learn the article "what are the characteristics of big data?"
Big data has four main features:
1.Volume: huge amount of data
Large volume is the most prominent feature that distinguishes big data from traditional data. Generally, the amount of data processed by relational databases is at the TB level, while the amount of data processed by big data is usually above the PB level.
2.Variety: many data types
The computer data type that big data deals with is no longer a single text form or a table in a structured database, it includes order, log, BLOG, Weibo, audio, video and other complex structure data.
3.Velocity: fast data flow
Speed is an important feature that distinguishes big data from traditional data. In the face of massive data, we need real-time analysis to obtain the needed information, and the efficiency of processing data is the life of the organization.
4.Value: high potential value of data
In the field of research and technology development, the above three characteristics are enough to represent the characteristics of big data. But in the field of business applications, the fourth feature is very critical! The reason why we have invested so much effort in research and technology development is that everyone
All have an insight into the potential great value of big data. How to "purify" the value of the data more quickly through powerful machine learning and advanced analysis and dig out the potential value of big data is a difficult problem to be solved under the background of big data's application.
These are all the contents of the article "what are the characteristics of big data?" Thank you for your reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
