What is data science? A 2 Z of fastest growing technology of the world
(What is Data Science)
Data science, the branch of science in which data is studied, in the same way as in space science, we study space.
Let us understand in detail,
There are many branches in the subject of science such as: – space science, biology, zoology, medical science, industrial-science etc.
Subject related data is very much in all of these and keeping all these data in a structured manner, studying it is not an easy task.
All these sciences are related to their own related subjects.
Whereas data science is such a science in which the data related to any subject of the world has to be kept in a very structured way.
So that further this data can be used in any analysis and desired information can be obtained.
Till a few years ago, no one knew anything about data science and today data science is a great need of the world.
why data science is important | Why is data science necessary?
Friends, whether it is education or business, healthcare sector or space research, tourism or grocery, there has been a lot of expansion in all fields.
A lot of data is generated in all the fields and it is a very difficult task to record, store or process/analyse all these data and also to get any specific desired information.
There are many mistakes in this, a small mistake can make a big difference in the final result.
In view of all this, a science was needed which could record, store or process/analyse not only Gigabyte (GB) or Terabyte (TB) data but also Petabytes (PB) or Exabytes (EB) data. Along with this one can get any specific desired information.
So this type of science is called data science.
In data science, both structured or unstructured types of data can be used.
Computers are used in data science but it is completely different from computer science. data science is mainly the science related to statistics
In which comes data collection (gather) data organization, data analysis and data presentation.
difference between data science and data mining
Most people remain confused about what is data science and what is data mining.
Data mining is a sub-discipline of data science, in which the data of its work is extracted from very large data and some specific software is used for them which are called data mining tools.
List of data mining tools used in data science
Many tools are used, some of which are as follows:-
- SAS Data mining
- Rapid Miner
- Oracle Data Mining
- Apache Mahout
- Advanced miner
- Analytic Solver
- Tanagra etc.
Who is a data scientist?
Those professional experts working in data science, who work on big data (very large amount of data), do data mining.
And according to the requirement of his company / clients, share his data analysis with the senior leadership, management or his clients of the company, are called data scientists.
