Data is everywhere, all pervasive, omnipresent and infinite. At the outset, it might be a bit hard to comprehend the universal perspective of data. As we move along, it will become apparent that data has impact on all quarters of life and every second, data is churned in huge numbers.
The quantum of data generated is mind boggling and it is hard to assign a fixed number today because the size keeps growing at exponential rate every second. This explosion of data happened ever so quickly and the unit of measurement norm today is in peta bytes and zeta bytes. To provide a context to the size of data, GB = 1,000,000,000 and ZB = 1,000,000,000,000,000,000,000.
Millions of data is captured all around us every second for different needs and purposes. Since data always is singular in nature, the reasoning behind every datum needs a thorough study. Each recorded observation of data has to be perceived from the right angle in order to make sense. Data is a phenomenon that cannot be realized until you look at the right place for the right content with right context in order to understand different drivers that influence data generation. Data Warehousing, Business Intelligence & Analytics field(s) are dependent on deep understanding of the different drivers in order to execute the right analysis and correct interpretation of data.
