Web 1.0 (Simple Web), Web 2.0 (Social Web), Web 3.0 (Semantic
Web), Web 4.0 (Smart Web), still and dynamic images, and so on are
the prominent and dominant sources of data. Sensors and actuators
are deployed abundantly in specific environments for security and for
enabling the occupants and owners of the environments to be smart.
In short, every kind of integration, interaction, orchestration, col-
laboration, automation, and operation produces streams of decision-
enabling data to be plucked and put into transactional and then into
analytical data stores. As the world and every tangible item in it are
connected purposefully, the data-generation sources and resources are
bound to grow ceaselessly, resulting in heaps and hordes of data.
4.2.2 Describing the Big Data World
We have discussed the fundamental and copious changes happening
in the IT and business domains. e growth of service enablement of
applications, platforms, infrastructures (servers, storages, and network
solutions) and even everyday devices besides the varying yet versatile
connectivity methods has laid down strong and simulating founda-
tions for big interactions, transactions, automations, and insights. e
tremendous rise in data collection along with all the complications
has instinctively captivated both business and IT leaders and lumi-
naries to act accordingly and adeptly to take care of this impending
huge and data-driven opportunity for governments, corporations, and
organizations. is is the beginning of the much-discussed and dis-
coursed big data computing discipline.
is paradigm is becoming formalized with deeper and decisive
collaboration among product vendors, service organizations, inde-
pendent software vendors, system integrators, and research organiza-
tions. Having understood the strategic significance, all the different
stakeholders have come together in complete unison to create and
sustain simplifying and streamlining techniques, platforms, and infra-
structures; integrated processes; best practices; design patterns; and
key metrics to make this new discipline pervasive and persuasive.
Today the acceptance and activation levels of big data computing are
consistently on the climb. However, it is bound to raise a number of
critical challenges but at the same time, if taken seriously it will be
highly impactful and insightful for business organizations to traverse
