Introduction of big data
Big data is also a data which are very large in size. Big data means huge data that increases over time.
Big data term is used to describe a large amount of data.
Usually we work on megabytes and gigabytes size but the size of big data is in terabytes of Petabytes or Exabytes or even more.
Big data is in different formats that cannot be handled by traditional tools and applications and constantly increasing the size of this data.
Example
Facebook’s database generates more than 500 terabytes of data every day, this data is generated mainly by commenting photos and videos upload messages, etc
Types of Big Data
Big Data' could be found in three forms:
Structured
Structure data is data that is well-organized and through which we can easily get information. Big data contains a large amount of data, out of which the data is well organized and can be easily stored, processed and analyze.
So structure data refers to highly organized information that can be used easily.
structure data can be stored in tabular column such as relational database.
For example:
Their are 5000 employees in an organization , maintaining data of all theses employees, storing them, processing and analyzing them so that we can easily get any information and take any decision. Because structure data is limited data and does not produce any confusion.
