Even now, a lot of digital information beyond imagination is being accumulated all over the world. Not only the amount of information is increasing, but the production rate of one is also getting speedy. This explosion of information has some reasons. The main reason is technology development. It can actualize things which were impossible in the past. The digital technology changes a lot of information into digitization. Also, many people utilize them with the powerful mean digital device. Men communicating by information contributed to increase the amount of information. Humans who escaped from illiteracy and economic hardship have generated many kinds of information, which are utilized in several fields such as politics, economy, law, culture, science, and so on. The production rate of information is faster than the speed of technology development. Though the digital devices handling the information are getting various, storage space is not enough to store the increased information. Sea is not calm, but it has that big waves. Likewise, lots of information comes to our life. It is important to judge what information is...

...Big Data Management: Possibilities and Challenges The term big data describes the volumes of data generated by an enterprise, including Web-browsing trails, point-of-sale data, ATM records, and other customer information generated within an organization (Levine, 2013). These data sets can be so large and complex that they become difficult to process using traditional database management tools and data processing applications. Big data creates numerous exciting possibilities for organizations, but along with the possibilities, there are challenges. Managers must understand the pitfalls and limitations, as well as the potential of big data (Levine, 2013). The focus of this report is the business potential and implications of big data as well as understanding the challenges and limitations of big data management. The potentials for big data are numerous; however, in this report only five potentials and implications for use are discussed. These include the following: knowledge management, social media, in travel, banking, and marketing and advertising. Knowledge Management One of the greatest potential for big data is knowledge management. A goal of knowledge management is the ability to integrate information from multiple perspectives to provide the insights required for valid decision-making such as where to invest marketing dollars, how much to invest, or whether to expand into a new geographic market (Lamont, 2012). In terms of knowledge management, three dimensions...

...examine the definition of big data. It also seeks to examine the components of a Unified Data Architecture and its ability to facilitate the analysis of big data. 2 WHAT IS BIG DATA Cuzzocrea, Song and Davis (2011) defined big data in part as being “enormous amounts of unstructured data produced by high-performance applications falling in a wide and heterogeneous family of application scenarios”. In recent years there has been an increasing interest and focus on big data. Many and varied definitions have been proposed but without a consensus on a single definition. The MIT Technology Review (2014), brought attention to the work of Ward and Barker (2014) which examined a number of definitions of big data that have attracted some general ICT industry support from leading ICT industry analysts and organisations such as Gartner, Oracle and Microsoft. In their work they proposed to provide a “concise definition of an otherwise ambiguous term”. The author having just attended a digital government conference with a large proportion of big data tagged presentations also noted that no single definition was offered. There was however a common content theme that supported the Ward and Barker definition of: “Big data is a term describing the storage and analysis of large and or complex data sets using a series of techniques including, but not limited to: NoSQL, MapReduce and machine learning.” 3 UNIFIED DATA ARCHITECTURE 3.1 WHAT IS THE UNIFIED DATA ARCHITECTURE?

...Big Data is a massive volume of data. It's usually so massive that it becomes complicated to comprehend using tools such as on-hand database, and traditional data processing applications. Some problems that come up are storage, sharing, analysis, and search.Even though these problems do occur it still can be helpful in business operations, and better business decisions. This data can also help give companies informations which can increase profit, bring more customers, and overall increase the business's value. Characteristics of Big Data include the five V’s. The first one is volume, which is the quantity of data. The second is Variety, which the type of Data. The third is velocity, which is the speed of the data is gathered. The fourth one Variability, which is inconsistency of data can hamper processes to manage it. The final one is Veracity, which is the quality of data captured can vary.

...Introduction to Big data Every day, 2.5 quintillion bytes of complex, every changing data are generated. (IBM) Data comes from social sites, digital images, transaction records, and countless unknown resources. The amount of data we generate daily is enormous, and the rate it is being generated is accelerating. As we head into a future where technology dominates the global market, this pace will only continue accelerate. Businesses and other entities are aware of this data and its power. In a survey taken by Capgemini and the Economist, over 600 global business leaders identified their companies as data driven and identified data analytics as an integral part of their business. Big Data solutions are considered the answer for handling this data converting it into useful information. According to the O'Reilly Radar Team (Big Data Now), Big Data consists of three variables – size, velocity and variety. Data is considered big if conventional systems cannot handle its size. It is not only that size of Big Data that matters, but also the volume of transactions that come with it. The second issue is how fast the data is generated and how fast if it changes (velocity). New data and updated data is constantly generated, and it must be processed and analyzed quickly to create real value for an organization. The final issue is data structure (variety). Data is typically collected in raw form, unstructured, from a variety of sources. To acquire useful information, data needs to be processed...

Click here to sign up for Information Management's daily newsletter to get the latest news, trends, commentary and more. The explosive growth in the amount of data created in the world continues to accelerate and surprise us in terms of sheer volume, though experts could see the signposts along the way. Gordon Moore, co-founder of Intel and the namesake of Moore's law, first forecast that the number of transistors that could be placed on an integrated circuit would double year over year. Since 1965, this "doubling principle" has been applied to many areas of computing and has more often than not been proven correct. When applied to data, not even Moore's law seems to keep pace with the exponential growth of the past several years. Recent IDC research on digital data indicates that in 2010, the amount of digital information in the world reached beyond a zettabyte in size. That's one trillion gigabytes of information. To put that in perspective, a blogger at Cisco Systems noted that a zettabyte is roughly the size of 125 billion 8GB iPods fully loaded.

...era of ‘big data’? Brad Brown, Michael Chui, and James Manyika Radical customization, constant experimentation, and novel business models will be new hallmarks of competition as companies capture and analyze huge volumes of data. Here’s what you should know. The top marketing executive at a sizable US retailer recently found herself perplexed by the sales reports she was getting. A major competitor was steadily gaining market share across a range of profitable segments. Despite a counterpunch that combined online promotions with merchandizing improvements, her company kept losing ground. When the executive convened a group of senior leaders to dig into the competitor’s practices, they found that the challenge ran deeper than they had imagined. The competitor had made massive investments in its ability to collect, integrate, and analyze data from each store and every sales unit and had used this ability to run myriad real-world experiments. At the same time, it had linked this information to suppliers’ databases, making it possible to adjust prices in real time, to reorder hot-selling items automatically, and to shift items from store to store easily. By constantly testing, bundling, synthesizing, and making information instantly available across the organization— from the store floor to the CFO’s office—the rival company had become a different, far nimbler type of business. What this executive team had witnessed first hand was the gamechanging effects of big data. Of course...

...Big Data Big Data and Business Strategy Businesses have come a long way in the way that information is being given to management, from comparing quarter sales all the way down to view how customers interact with the business. With so many new technology’s and new systems emerging, it has now become faster and easier to get any type of information, instead of using, for example, your sales processing system that might not get all the information that a manger might need. This is where big data comes into place with how it interacts with businesses. We can begin with how to explain what big data is and how it is used. Big data is a term used to describe the exponential growth and availability of data for both unstructured and structured systems. Back in 2001, Doug Laney (Gartner) gave a definition that ties in more closely on how big data is managed with a business strategy, which is given as velocity, volume, and variety. Velocity which is explained as how dig data is constantly and rapidly changing within time and how fast companies are able to keep up with in a real time manner. Which sometimes is a challenge to most companies. Volume is increasing also at a high level, especially with the amount of unstructured data streaming from social media such as Facebook. Also including the amount of data being collected from customer information. The final one is variety, which is what some companies also struggle with in handling many varieties of structured and unstructured data...

...Big Data and its Effects on Society Kayla Seifert MGT-311 November 23, 2015 Big Data is a concept that has existed for a while but only gained proper attention a couple of years ago. One can describe Big Data as extremely large data sets that have grown so big that it becomes almost impossible to manage and analyze with traditional data processing tools. Enterprises can use Big Data by building new applications, improving the effectiveness, lowering the costs of their applications, helping with competitive advantage, and increasing customer loyalty. It can also be used in other industries to enable a better system and better decision-making. Big Data has become a valuable asset to everyone around the world and continues to impact society today. The ideology of Big Data first came up in the days before the age of computers, when unstructured data were the norm and analytics was in its infancy. The first Big Data challenge came in the form of the 1880 U.S. census when the information involving about 50 million people being gathered, classified, and reported. This census contained a lot of facts to deal with, however, limited technology was available to organize and manage it. It took over seven years to manually put the data into tables and report on the data. Thanks to Big Data, the 1890 census could be placed on punch cards that could hold about 80 variables. Instead of seven years, the analysis of the data only took six weeks. Big Data allowed the government...

...Big Data/Predictive Analytics First Last Name Name of the Institution Big Data/Predictive Analytics Introduction There has been a controversial debate about the big data and the predictive analytics. With the evolution of technology and innovation, one fact needs to be appreciated that, the concept of the big data and the predictive analytics is here to stay. So it is up to the users to learn to deal with it and manage it to offset any adverse effects that may result. The proponents of the big data argue that the big data is advantageous, and the 21st-century generation benefits more from the big data and predictive analytics than the harm that the big data poses to their lives. The bottom line of the matter, however, is that, big data interferes with human’s privacy, ethics, and any unauthorized third party can access the personal data for evil purposes or their benefits. The definition of the big data takes the “3V” form; High-volume, high-variety and high-velocity information that demand the innovative forms of processing, cost-effective for improved insight and decision making. This technological definition does not encompass the societal aspect and. Therefore, it can be argued to be one-sided definition. To incorporate the societal aspect, the definition needs to be viewed in a broader manner so that the aspect of data analytics can come in. In this regard, the two terms can work together so that a meaning of full terms big data/ data analytics can denote the cloud...

...Big Data and Data Analytics for Managers Q1. What is meant by Big Data? How is it characterized? Give examples of Big Data. Ans. Big data applies to information that can’t be processed or analysed using traditional processes or tools or software techniques. The data which is massive in volume and can be both structured or unstructured data. Though, it is a bit challenging for enterprises to handle such huge amount fast moving data or one which exceeds the current processing capacity, still there lies a great potential to help companies to take faster and intelligent decisions and improve operations. There are three characteristics that define big data, which are: 1. Volume 2. Velocity 3. Variety * Volume: The volume of data under analysis is large. Many factors contribute to the increase in data volume, for example, * Transaction-based data stored through the years. * Unstructured data streaming in social media. * Such data are bank data (details of the bank account holders) or data in e-commerce wherein customers data is required for a transaction. Earlier there used to data storage issues, but with big data analytics this problem has been solved. Big data stores data in clusters across machines, also helping the user on how to access and analyse that data. * Velocity: Data is streaming in at unprecedented speed and must be dealt with in a timely manner. RFID tags, sensors and smart metering are driving the need to deal with...
