What is Big Data?

Before I say what big data is, I will explain about the questions that people often misunderstand about big data first. The most common myth associated with Big Data is that it is only about the size or amount of data. But in reality, it's not just about collecting "big" data. Big Data means a lot of data flowing in from different sources and different formats. Even before, there was a lot of information that was stored in the database. But due to the diverse nature of this data, traditional relational database systems are unable to handle this data. Big data is more than just a set of data sets of different formats. It is an important asset that can be used to benefit.

 

The three big data formats are different:

1.Structured: Organized data format with a fixed schema. Ex: RDBMS

2.Semi-Structured: Partially organized data which does not have a fixed format. Ex: XML, JSON

3.Unstructured: Unorganized data with an unknown schema. Ex: Audio, video files etc.

 

Characteristics of Big Data

These are the following characteristics associated with Big Data:

-Validity: correctness of data

-Variability: dynamic behavior

-Volatility: tendency to change in time

-Vulnerability: vulnerable to breach or attacks

-Visualization: visualizing meaningful usage of data

 

In general, big data analysis, most companies that facilitate the development and development, mainly related to the use of algae, data mining in various data sets.

The significant increase in data collection and processing capabilities has greatly improved the ability of weather forecasters to pinpoint the time and severity of hurricanes, floods, snowstorms and other weather events. Globally, more and more evidence of climate change is prompting governments and scientists to take action to protect people and property from its effects. But to take effective measures, they need to know more about the weather-from everything that will happen tomorrow to what will happen next year. According to the professor of economics and finance , Alan Anderson, PhD , “Example of an application of big data to weather forecasting is IBM’s Deep Thunder. Unlike many weather forecasting systems...
