With the recent exponential growth of ICT, there is explosive growth of data of varied nature. Human effort is always to efficiently store the data for the current and future usages. In the present day, the people create data with a speed that 90% of the total data in the world today has been created in the last few years alone, as explained by IBM. There are many problems and challenges to handle this big data i.e. heterogeneity, scale, timeliness, complexity, and associated privacy. One has to develop suitable and flexible strategies to derive knowledge and value from this price less data. Data analysis, organization, retrieval, and modeling are foundational challenges.
