As the advancement in the technologies across the globe have catch the lightning speed, technologies like Big Data, IoT and blockchain have make their individual identity and proven to be an asset to the various global industries. In this era, almost every techie person knoww each of them independently and also many do know their combined uses and its benefits, but for the sake of novice readers, let us see the brief of each of them.
As the name suggest, Big Data is the Data which is in Large Volume. Data can be of various types i.e. Structured Data (database – which is in order), Unstructured Data (Traditional Row-Column Storage) or Semi Structured Data (Unstructured data with some organizational properties).
There are many industries that can be efficiently be benefitted with big data analytics solutions i.e. Healthcare, Retail – Consumer, Finance Services, Web and Digital Media, Telecommunication, eCommerce & customer Service etc., where Data is in massive volume – thus, storage & further analytics needs to be done by Big Data Management Tools. Also, there are n- number of tools in the market from using which, we can manage the Big Data i.e. Hadoop, Apache Spark/Storm, Ceph, Google Big Query etc.
In simple words, IoT is the ‘Active Things’ connected to Internet. These ‘Active Things’ can be Sensors, Devices, Appliances, Vehicles etc. They either collect & send some information over some server through Internet or they receive information & act upon it or they can do both. In the upcoming days, the requirement will be of the third type – they collect information & send and also they receive some information and react accordingly. There are thousands of application of such devices in theory which will soon become reality. Also, these kind of applications will be on massive scale across varied industries and the data transferred will be in huge – managed by Big Data applications. Some examples can be taken as IoT for Buildings (Homes, Offices and Parking spaces etc.), IoT in Agriculture, IoT in Automobiles and IoT in Healthcare Sector and so on.
blockchain technology was came to light with the origins of Bitcoin. But as the time passed, it was realized that the same technology can be used for many things (various databases -which has some value), apart from just doing financial transactions securely. Blockchain technology have distributed architecture for database system. It does not have any centralized address of data, rather data is replicated as part of ‘Blocks’ at multiple machines (called nodes) on internet, thus being very difficult to hack for anyone.
In Blockchain database, each record with some key (hash code) is known as ‘Block’. It contains details like Time Stamp for particular transaction and key to previous ‘Block’ in Chain, which is also replicated at various locations/nodes.
