A majority of the masses confuse the term ‘Big data’ and what is big data?, with the volume or size of data from the sound of its name. However, this is simply not the case. Sure, Big data is enormous and ‘big’ in number, but it isn’t just limited to the amount of data. It reaches much more beyond its volume and size.
So exactly what is big data?
It can be defined as the overwhelming amounts of data that keeps accumulating from various sources all over. This type of data is available in different types of formats. The relational traditional type of database systems are not capable of managing this kind of data, this is because of the miscellaneous nature of this kind of data.
However, one thing is for sure and that is – it exceeds the cube of being an assemblage of many databases that are available in different formats. It can be made use of for obtaining a number of benefits, this has been made possible because big data is a crucial asset. It is available in about three different kinds of formats, they are
- a) structured,
- b) semi structured,
- c) Unstructured.
In the case of structured, the example that can be seen is RDBMS, the data is present in an organized manner along with a fixed and immobile schema.
On the other hand, in semi-structured we can see data that is partially organized and is not available in a fixed format. The example here is JSON and XML. When it comes to unstructured data,
The data is in an unorganized format along with a schema that is unknown. The example that we can see in unstructured is the video as well as audio files, and many more.
