While writing an email, calling, texting, tweeting, streaming audio and video, playing game, online shopping, reservation, user activity generates data about their needs and preferences, as well as the quality of their experience with millions of machines and process every moment of every fraction of a time. Even when we are not using our devices, the network is generating time, location, offline records, pending messages and other data that keeps services running and ready for next use. Organization are starting to appreciate the importance of using more data in order to support decisions and arrangements for their strategies. There considered and proved through the study and practical implementation cases that More Data usually beats better structure and management. A massive sets of data gives a better output and wide range of correlations but also working with it can become a challenge due to limitations of processing. So Organizations initiated to evaluate that they can chose to invest more in processing massive sets of data rather than investing in costly algorithms and techniques. Vision of big data is that organizations will be able to reap and harness every byte of relevant and interrelated data and use it to make the best decisions. Big data technologies not only consider solution for massive sets of data, but more importantly, the ability to understand and take advantage of its full value. There is a lots of new challenges to handle big data, real-time communication, and decisions create lots of other challenges and issues regarding analyzing, management and processing. This article intends to define the concept of Big Data and stress the importance of Big Data. This paper also throws some light on other challenges and issues. Keywords Massive Data Sets, Big Data, Analytics, Correlations, Scalability. I. INTRODUCTION big data is an all broad term for any collection of data sets so massive and complex and that increase complexity to process them using classical data processing applications. The processing applications cover analysis, capture, curation, search, sharing, storing, transfer, visualization, privacy violation, and secure infrastructure that is too divers, fast changing or massive for conventional technologies, skill and infrastructure to address efficiently. Every second, minute, and an hour, we create millions bytes of data and that s too much from last decades. This data comes from everywhere: social media sites and response, digital records like picture, movie, fingerprint data, climate information from sensors, GPS and GIS data, Financial data, Transportations, Health and Hospitalities to name a few and this is a big data. Nowadays big data is a growing torrent some of examples are 1639 millions of mobile users worldwide in 2014[2] and they are producing data, 600TB data per day processed by Facebook[3], 10000 PB data stored in NSA data center[4], 235 terabytes data collected by the US library of congress by April 2011, 10 gigabytes of data may be transferred from its servers every second in CERN LHC Project, Amazon generates over $80,000 in online sales, 2.7 ZB of data exist in the digital universe today and they are few. With expanding of data, big data is capturing its value.other way we are living in a voluminous informational environment and we are moving a knowledge based environment. But voluminous informational environment provide better decision after analysis it. How much data generate by company, government and any entity that belongs to universe represents a big space where great amount of information added every time.

The swelling ranks of organizations that increasingly depend on big-data technologies include dozens of familiar names and a growing number you ve never heard of. II. DEFINITION OF BIG DATA There are some of definitions of big data In IBM s view Big Data has four aspects: volume, velocity, variety and veracity. Volume: refers to the quantity of data gathered by a company. This data must be used further to obtain important knowledge; Velocity: refers to the time in which Big Data can be processed. Some activities are very important and need immediate responses, that is why fast processing maximizes efficiency; Variety: Refers to the type of data that Big Data can comprise. This data can be structured as well as unstructured; Veracity: refers to the degree in which a leader trusts the used information in order to take decision. So getting the right correlations in Big Data is very important for the business future. [4] VOLUME Data at Rest, Ofload or cold data in TB, PB Redundancy elimination Transactions, Retention Records,Tables, Files VELOCITY Data in Moion, In Stream, In Batch Analysis to enable decisions within fractions of a seconds VARIETY Data in many forms Structured Unstructured Semistructured Data access midleware and ETLM VERACITY Data in doubts Data uncertainity Managing the reliablity and predictability of inherently imprecise data types Big data is the term increasingly used to describe the process of applying serious computing power the latest in machine learning and artificial intelligence to seriously massive and often highly complex sets of information."[5] Big Data: when the size and performance requirements for data management become significant design and decision factors for implementing a data management and analysis system. For some organizations, facing hundreds of gigabytes of data for the first time may trigger a need to reconsider data management options. For others, it may take tens or hundreds of terabytes before data size becomes a significant consideration. [6] "Big data (also spelled Big Data) is a general term used to describe the voluminous amount of unstructured and semistructured data a company creates -- data that would take too much time and cost too much money to load into a relational database for analysis. Although big data doesn't refer to any specific quantity, the term is often used when speaking about petabytes and Exabyte s of data."[7] The definition of Big Data is very fluid, as it is a moving target what can be easily manipulated with common tools and specific to the organization: what can be managed and stewarded by any one institution in its infrastructure. One researcher or organization s concept of a large data set is small to another. [8] We define Big Data as a cultural, technological, and scholarly phenomenon that rests on the interplay of: (1) Technology: maximizing computation power and algorithmic accuracy to gather, analyze, link, and compare large data sets. (2) Analysis: drawing on large data sets to identify patterns in order to make economic, social, technical, and legal claims. (3) Mythology: the widespread belief that large data sets offer a higher form of intelligence and knowledge that can generate insights that were previously impossible, with the aura of truth, objectivity, and accuracy.[9]

Big Data Introduction, Importance and Current Perspective of Challenges 223 By Roger Magoulas from O Reilly media first introduced to the computing world Big Data term in 2005 in order to define massive amount of data that traditional data management techniques cannot manage and process due to the complexity and size of this data A study on the Evolution of Big Data as a Research and Scientific Topic shows that the term Big Data was present in research starting with 1970s but has been comprised in publications in 2008. Nowadays the Big Data concept is treated from different points of view covering its implications in many fields. According to MiKE 2.0, the open source standard for Information Management, Big Data is defined by its size, comprising a large, complex and independent collection of small data sets, each with the potential to interact. In addition, an important aspect of Big Data is the fact that it cannot be handled with standard data management techniques due to the inconsistency and unpredictability of the possible combinations. The Oxford English Dictionary (OED) defines big data as an extremely large data sets that may be analysed computationally to reveal patterns, trends, and associations, especially relating to human behaviour and interactions: much IT investment is going towards managing and maintaining big data In 2011 big data study by McKinsey highlighted that definitional challenge. Defining big data as datasets whose size is beyond the ability of typical database software tools to capture, store, manage, and analyze, the McKinsey researchers acknowledged that this definition is intentionally subjective and incorporates a moving definition of how big a dataset needs to be in order to be considered big data. As a result, all the quantitative insights of the study, including the updating of the UC Berkeley numbers by estimating how much new data is stored by enterprises and consumers annually, relate to digital data, rather than just big data, e.g., no attempt was made to estimate how much of the data (or datasets ) enterprises store is big data. In addition, in Gartner s IT Glossary Big Data is defined as high volume, velocity and variety information assets that demand cost-effective, innovative forms of information processing for enhanced insight and decision making. In a simpler definition we consider Big Data to be an expression that comprises different data sets of very large, highly complex, unstructured, organized, stored and processed using specific methods and techniques used for business processes. There are a lot of definitions on Big Data circulating around the world, but we consider that the most important one is the one that each leader gives to its one company s data. The way that Big Data is defined has implication in the strategy of a business. Each leader has to define the concept in order to bring competitive advantage for the company. III. IMPORTANCE OF BIG DATA The main importance of big data exist because more data more accurate results. Big data consist in the potential to improve efficiency in the context of use a large volume of data, of different type and various kind of dimensions. If big data is defined properly and used efficiently all over, organization can get a better view on their business therefore leading to efficiency in different areas like sales, improving the manufactured product, health report, data selection, statistical sample and so forth. Big data can be used effectively in the context of- 1. Big Data can provide transparent way of significant value by making and processing information. There is still a massive information not in digital form, e.g. traditional and classical records, sensors based data, or not textual based data not easily accessible and searchable through networks due to source of efficiency. 2. As organization create, store and process more transactional data in digital form, they can process more accurately and detailed efficiency and performance on everything from records and expose flightiness and boost functionality. In fact organization can store, analyse, process, and control big data using controlled experiments to make accurate decision. 3. Big Data allows segmentation of records and therefore much more precisely made-to-measure products or services.

IJAEST, Volume 4, Number 3 Vinod Sharma et al. 4. More data more analysis more accurate results that improve decision-making, minimize risk, and expose valuable fact from insights that would otherwise remain hidden. 5. Big Data can be used to develop the next generation of products and services. 6. Big Data act as a bridge the Gap between IT and Business 7. Big data can create new business model based on legacy and classical data 8. Getting the Right Information for Your Business 9. In information technology in order to improve security and troubleshooting by analyzing the patterns in the existing logs and events; 10. In customer service by using information from call centers in order to get the customer pattern and thus enhance customer satisfaction by customizing services; 11. In improving services and products through the use of social media content. By knowing the potential customers preferences the company can modify its product in order to address a larger area of people; 12. In the detection of fraud in the online transactions for any industry; 13. In risk assessment by analyzing information from the transactions on the financial market. 14. Big data can provide better results and transformative potential in Health care, Public Sector Administration, Retails, Manufacturing, and Personal Location, Proving the Value in IT to Business. Big data can do much more that are listed from above but that follow some inconsistencies and issue due its wide features like Volume, Velocity, Variety, Veracity, Value and many others. IV. BIG DATA CHALLENGES AND DILEMMAS Big Data is rapidly growing day by day due to massive data sets that comes from various resources but also reflects the trend in field of science and technology, this trend opens the door to understanding the data world and its hidden part for making decisions. Volume is not entirely the issue of big data but processing, analysis and controlling of traditional, structured, and unstructured data. Structured data depend on process and type s storage but need to differentiate in between data-driven-process and process-driven-data. Nowadays big data handling requirements are completely different from traditional data platform. Some of challenges are facing nowadays 1. The understanding of big data structure is major concerns before storing, processing, analyse it. According to IBM Volume, Velocity, variety, and Veracity is important factor but handling big data require more (e.g. values). There the time is important factor in transactional analysis because some of them need to be require highly frequent in order to accessing fast any change in the environment. 2. Considering the concept that Big Data is new in Organization, it is necessary for these organization to learn how to use new technology after invention of it in competitive age. 3. Prepare IT Specialist for handling big data. Only right talent can handle new technology and interpret the data for meaningful information for business. According to McKinsey s study on Big Data called Big Data: The next frontier for innovation, there is a need for up to 190,000 more workers with analytical expertise and 1.5 million more data- literate managers only in the United States. This statistics are a proof that in order for a company to take the Big Data initiative has to either hire experts or train existing employees on the new field. [10] 4. Privacy and Security is major challenges for big data. Because Big Data consists a massive amount of complex structure data, and it is very tedious for a company for considering security, privacy and authentication levels according to users and process. If we developing big data platform for handling global business need then consider capability of security in various range.

Big Data Introduction, Importance and Current Perspective of Challenges 225 5. There is difficult to identify the right data for right process or user and determining best utilization of this and that very different from the traditional platform. 6. Accessibility and connectivity of big data from third party processing data points is in initial phase of development. A majority of data points are not yet connected today, and organization often do not providing right platforms for access and processing the data across the enterprise. Organization offering some of utilities to integrate operational technologies, such a real-time grid management, cloud, with information technologies like smart metering. 7. Big Data rapidly change day by day and data world is evolving fast. IT architecture require a strong innovative technological partner that can help for adapt rapidly changes in big data. 8. Major organization need continuous availability and high scalability of Big Data Platform. Because your data never go down due to high scalability from different data centers. 9. Flexible design for multiformity of workload. Because dimension of big data in various range. 10. Cost of platform doesn t have to break the bank. IV.CONCLUSION Nowadays big data entering in our life in the context of better processing, and results. This technology emerging various kind of technology and provide values from discovery of knowledge. In this paper we discuss about basically three issues Definition, Importance and Challenges of big data. We discuss which definition is suitable for current scenario of big data then answer of why we using big data after that challenges of acquire big data. Today lot of platforms and challenging situations are there ahead of this world to make new technologies for both processing and storage. Extensions of traditional database technologies are also discussed to deal with big data. So more technologies can be made to deal with big data processing and storage to make it more concise and meaningful. REFERENCE [1] IBM, IBM BIG DATA. [Online].
