Here is Gartner’s definition, circa 2001 (which is still the go-to definition): Big data is data that contains greater variety arriving in increasing volumes and with ever-higher velocity. The 10 Vs of Big Data #1: Volume.  |  Volume is how much data we have – what used to be measured in Gigabytes is now measured in Zettabytes (ZB) or even Yottabytes (YB). Big Data involves working with all degrees of quality, since the Volume factor usually results in a shortage of quality. Gartner stated that in 2011, the rate of data growth globally was around 59%. In recent years, Big Data was defined by the “3Vs” but now there is “5Vs” of Big Data which are also termed as the characteristics of Big Data as follows: 1. Big data is a collection of tools and methods that collect, systematically archive, and … SOURCE: CSC The image below shows the relationship between the two forms of data. Currently, for organizations, there is no limit to the amount of valuable data that can be collected, but to use all this data to extract meaningful information for organizational decisions, data science is needed. Data science is evolving rapidly with new techniques developed continuously which can support data science professionals into the future. This infographic from CSCdoes a great job showing how much the volume of data is projected to change in the coming years. This article was originally published here and reposted with permission. Volume: The name ‘Big Data’ itself is related to a size which is enormous. Maybe this is why that most focus on one specific V: Volume. Hence, BIG DATA, is not just “more” data. The terms data science, data analytics, and big data are now ubiquitous in the IT media. It makes no sense to focus on minimum storage units because the total amount of information is growing exponentially every year. Economic Importance- Big Data vs. Data Science vs. Data Scientist. The volume of data refers to the size of the data sets that need to be analyzed and processed, which are now frequently larger than terabytes and petabytes. Since the two fields are different in several aspects, the salary considered for each track is different. Figure: An example of data sources for big data. All too often definitions and key concepts in the data / BIG DATA world are not shared amongst practitioners, and fashions and fads take over. Volume is a huge amount of data. Data science is a specialized field that combines multiple areas such as statistics, mathematics, intelligent data capture techniques, data cleansing, mining and programming to prepare and align big data for intelligent analysis to extract insights and information. This tutorial explains the difference between big data vs data science vs big data analytics and compares all three terms in a tabular format. Big data, on the other hand, are datasets that are on a huge scale; so much so that they cannot usually be handled by the usual software. On the other hand, Big Data is data that reveals information such as hidden patterns during production, which can help organizations in making informed business decisions capable of leading constructive business outcomes and intelligent business decisions. Although the concepts are from the same domain, the professionals of these platforms are believed to earn varied salaries. Artificial Intelligence is the consequence of this process. Too often, the terms are overused, used interchangeably, and misused. Currently, all of us are witnessing an unprecedented growth of information generated worldwide and on the internet to result in the concept of big data. We have all the data, … The potential here is that if we crunch true BIG DATA, we can make an attempt to establish patterns and correlations between seemingly random events in the world. Big data approach cannot be easily achieved using traditional data analysis methods. Big data originally started with three V's, as described in big data right data, then there was five, and then ten. Traditional analysis tools and software can be used to analyse and “crunch” data. Big Data definition – two crucial, additional Vs: Validity is the guarantee of the data quality or, alternatively, Veracity is the authenticity and credibility of the data. In practice, BIG DATA is almost always to do with multiple sets of data, and in most cases, has little to do with personal data (though probably personally identifiable data is likely to be ubiquitous, given that sufficient correlation of multiple datasets could make personal data “fingerprints” unique). Due the complexity of BIG DATA and computational power / (new) methods required, this has only been possible to attempt in the last decade or so. It takes responsibility to uncover all hidden insightful information from a complex mesh of unstructured data thus supporting organizations to realize the potential of big data. Big data workers find it very appreciating for a company and so they started to think about smoother and faster production of big data. In big data vs data science, big data is generally produced from every possible history that can be made in an event. Data science is a scientific approach that applies mathematical and statistical ideas and computer tools for processing big data. Value denotes the added value for companies. Today, many more excellent tools, platforms and ideas exist in the field of good management of data (not just BIG DATA). This creates an enormous and immediate potential for the Public Sector in making relevant and timely improvements in “small” data management, data integration and visualisation. Arguably, it has been (should have been) happening since the beginning of organised government. Data and its analysis appeared to sit as an ‘appendix’ on the side of government. The Trampery Old Street, 239 Old St, London EC1V 9EY Contrary to analysis, data science makes use of machine learning algorithms and statistical methods to train the computer to learn without much programming to make predictions from big data. The table below provides the fundamental differences between big data and data science: The emerging field of big data and data science is explored in this post. Only useful information for solving the problem is presented. Velocity refers to the speed at which the data is generated, collected and analyzed.
