BIG DATA :MEANING, CHALLENGES, OPPORTUNITIES,APPLICATIONS,TOOLS Big data is certainly one of the biggest buzz phrases in it today. The term ’Big Data’ appeared for first time in 1998 in a Silicon Graphics (SGI) slide deck by John Mashey with the title of ”Big Data and the Next Wave of InfraStress” [9]. -Combined with virtualization and cloud computing, big data is a technological capability that will force data centers to significantly transform and evolve within the next five years. Similar to virtualization, big data infrastructure is unique and can create an architectural upheaval in the way systems, storage, and software infrastructure are connected and managed. Big data is an amalgam of large and varieties of data sets including structured data, semi structured data and unstructured data so it’s beyond the capability of traditional tools to capture, store, process and analysis of big data. It is true that big data have capability of unlocking new sources of development in many fields but at the same time researchers are being confronted challenges with big data. This paper reveals the various challenges faced with big data and opportunities realized with big data. Keywords: Big data, Challenges, Opportunities, Security Issues. INTRODUCTION: Big data refers to the collection and subsequent analysis of any significantly large collection of data that may contain hidden insights or intelligence (user data, sensor data, machine data). when analyzed properly, big data can
Abstract- Big data is a hot research topic in today’s world. Data has become an indispensable part of every economy, industry, organization, business function and individual. With the fast growth now-a-days organizations has filled with the collection of millions of data with large number of combinations. This big data challenges over business problems. Big Data is a new term used to identify the datasets that due to their large size and complexity. Big Data mining is the capability of extracting useful information from these large datasets or streams of data, that due to its volume, variability, and velocity. We address broad issues related to big data and/or big data mining, and point out opportunities which help to reshape the subject area of today’s data mining technology toward solving tomorrow’s bigger challenges emerging in accordance with big data.
Big data is used to refer to availability of massive volume of data, both structured data and unstructured data, (Viktor & Kenneth, 2014). The data is so large and grows exponentially that processing it using traditional techniques is difficult. The data is not only massive, but also diverse and fast changing. Organizations, therefore, require modern techniques, infrastructure, and advanced personnel skills to address it efficiently. In simple terms, the volume, variety, and the velocity of the data is too great.
Big Data is an expansive phrase for data sets so called big, large or complex that they are very difficult to process using traditional data processing applications. Challenges include analysis, capture, curation, search, sharing, storage, transfer, visualization, and information privacy. In common usage, the term big data has largely come to refer simply to the use of predictive analytics. Big data is a set of techniques and technologies that need or require new forms of integration to expose large invisible values from large datasets that are diverse, complex, and of a massive scale. When big data is effectively and efficiently captured, processed, and analyzed, companies
Big data is nothing but collecting of datasets. Organizations in current world demands data to be broken down which can used to get more high effectiveness and benefit. Big data refers to the large amounts of data which collected from various devices such as mobiles, sensors and social media etc. Generally, large amount of data have been regenerating by IT industry such as satellite data, mobile devices and etc. This data is being growing rapidly day by day and it would be referred as Big Data.
Big data is a relatively recent concept in the marketing world that describes the process of analyzing massive data sets to uncover trends. The data sets are so large that it would be almost impossible to find such trends without high-powered analytical technology. Big data has been facilitated by the ability to gather massive amounts of information about consumer profiles and shopping trends. The primarily facilitators of big data collection are credit card companies and online companies like Google and Facebook that track people's purchasing and computer usage patterns. Big data has been used in a lot of different industries to revolutionize everything from health care to manufacturing to government (Manyika, et al,
Big data refers to the data sets whose size is bigger than traditional data base tools and contains the ability to acquire, store, manage and analyze data (Watson, H.J., & O. Marjanovic, 2013). Big data often has the following four characteristics, that is to say, it has a vast volume of data, fast transferring and dynamic system of data, a variety types of data and huge value of data. As the development of big data is faster and faster, the use of it also becomes broader and boarder, like researching on customers’ preference, taking it on military use and so on. This essay will mainly discuss the influences big data has on consumers.
Let us start by defining Big Data. Big Data is the term for datasets that are too big to process in traditional ways such as databases and simple analytics software. The size of big data is a moving target as storage and processing capacities grow. Because these datasets are so big (100 petabytes if you are Facebook for example) when working with them, you face a few challenges: storage space, searching, analysis, and
Five years ago, few people had heard the phrase ‘Big Data.’ Today, it’s hard to go an hour without seeing it implemented practically in our daily life. The promise of a highly accurate data-driven decision-making tool is an attractive lure for any organization in any industry. However, big data is not without its own problems.
Although we hear the term ‘big data’ frequently now, the true definition of big data does not seem to have a singular, agreed upon definition. Depending on who you ask, big data can mean many different things. What would seem to be the most intuitive definition of ‘big’ data is not necessarily the correct one. Though the size of the data is an important aspect, it is not always the defining factor. According to Dell EMC’s video, Big Ideas: How Big is Big Data, big data is “any attribute that challenges the constraints of system capability or business need.”1 Will Hakes, Co-Founder and CEO of Link Analytics, claims that big data cannot be defined in precise terms and is, effectively, a “rallying cry.”2 Hakes does, however, agree that any
Big data is often referred to and defined in many different ways.In layman terms, we can interpret it as massive or huge amounts of information which cannot be handled efficiently by the current technologies and softwares. But recent technological advancements like data analytics, and social or media networks allow process, transfer, allocate, measure and represent enormous amounts of data which can also be referred to as Big Data.
Big data is an extensive collection of structured and unstructured data. It is a modern day technology which is applied to store, manage and analyze data that are not possible to manage, store and analyze by using the commonly used software or tools. Since all of our daily tasks are overtaken by the modern technologies and all the businesses and organizations are using internet system to operate, the production of data has increased significantly in past
You may have heard the term “Big Data” often these days and the importance of analytics attached to it. The availability of good data set and analytics of it provide organizations ability to understand consumer behavior and future prospects. This has now become an essential part of every business operation. Data itself is not a new thing to humans, written records have been in existence since 4th millennium BC. What has changed recently is that with digital inventions and significant growth in internet access, most people are on the electronic grid for longer periods and spending lot of time on emails, messaging, entertainment and social media applications. This huge growth in data generation has given birth to the concept of
Big data is a popular term used to describe the improvement and availability of data in both structured and unstructured formats. Structure data is located in a fixed field within a record or file and it is present in the relational data bases and spreadsheets whereas an unstructured data file includes text and multimedia contents. The primary objective of this big data concept is to describe the extreme volume of data sets i.e. both structured and unstructured. It is further defined with three “V” dimensions namely Volume, Velocity and Variety, and two more “V” also added Value and Veracity. Volume refers to the amount of data, Velocity depends upon the speed of the data processing, Variety is described with the types of the
The massive amount of data available is where the term “big” data comes from. The processing power of a typical server is not vast enough to store this data; new technologies help to ease this burden. To put into perspective how much data is out there, six billion people today have cell phones that are transmitting data. Most United States company currently store a minimum of one-hundred terabytes. It is estimated that by the year 2020, there will be forty zettabytes of data available. This is three-hundred times the amount available in twelve years ago.
