INNARDS OF BIG DATA
ABSTRACT
Data is the very crucial part for every organization, economy, business world and individual. Big data is the term for data sets so large and complicated that it becomes difficult to process using traditional data management tools or processing applications. 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. This paper presents the theoretical overview of big data contents, challenges, data storage technologies, big data analytics.
Keywords:Big data, Challenges, Bigdata analytics, Hadoop.

In most enterprise scenarios the data is too big or it moves too fast or it exceeds current processing capacity In 1997, NASA scientist used the term big data because they found difficulty with data set that is so large that they even do not get fit inside memory disk etc. They called that big data problem. It’s an interesting challenge to manage such data. Then some American scientist in 2008 popularized the term big data because they predict that big data analysis can enable unlocking of valuable knowledge and helps in decision making in varieties of fields like medical, science, agriculture, industries etc. Big data cannot be considered in isolation .it is combination of various data management technologies that progresses over the time. Big data is all about large volume, diversified data that is captured from various data sources and analysed at high velocity to provide valuable insights. In the past years big data size was in terabytes but today it is in petabytes and soon it will be in Exabyte (millions of terabytes) So it’s necessary to understand big data from all aspects and dimensions.Big data encompasses high velocity, high volume and variety of data like structured data, semi structured and unstructured data that have potential of unlocking new sources of development, providing …show more content…
That data is not in proper organised form. For example: html, xml Since big data is collection of structured, unstructured and semi structured data so big data have enough potential to do tasks that were impossible earlier like disease management, crime management, providing new direction in business enterprises.[3]. Many areas or fields of science currently facing exponential growth in volume of data as compared to past years. It is true that big data revolutionized the research field but at same time challenges are faced in dealing with big data so there is need of emergence of new technology to utilize full potential of big data and addressing confronted challenges.As discussed by The Economist [2 panel panel] “Managed well, the data can be used to unlock new sources of economic value, provide fresh insights into science and hold governments to
Hadoop [8] is an open source implementation of MapReduce programming model which runs in a distributed environment. Hadoop consists of two core components namely Hadoop Distributed File System (HDFS) and the MapReduce programming with the job management framework. HDFS and MapReduce both follow the master-slave architecture. A Hadoop program (client) submits a job to the MapReduce framework through the jobtracker which is running on the master node. The jobtracker assigns the tasks to the tasktrackers running on many slave nodes or on a cluster of machines.
The data processing tasks for all the tools is Map Reduce and it is the Data processing tool which effectively used in the Big Data Analysis[13]. For handling the velocity and heterogeneity of data, tools like Hive, Pig and Mahout are used which are parts of Hadoop and HDFS framework. It is interesting to note that for all the tools used, Hadoop over HDFS is the underlying architecture. Oozie and EMR with Flume and Zoo keeper are used for handling the volume and veracity of data, which are standard Big Data management tools [13].
I believe the impetus behind the exploration and colonization in the era of European exploration was for multiple different incentives for example, wealth, religion, and fame. Moreover, wealth and power were obtained through trading goods, valuables, gold, silver, lands, and colonies. In addition, looking for the Northwest Passage to Asia and fur trading were critical factors that defined the wealth aspect. Also, converting Native Americans to Roman Catholicism played a significant role in the expansion of colonies. Furthermore, the English came to America in search for freedom of religion.
Homeroom Reflection Junior year I have grown as a student this semester by watching the mala movie. This has helped me grow as a student because it showed me how just one voice can change so much in a community. From this experience I learned how Mala was an ordinary girl but who ones spoke up for what she believed was right for her community and the people all around her. After she started to change her community on a positive way for example, have more schools so students can have an education and making sure girls were able to attend school more often. Therefore, when she spoke up for what she thought was right and changed people 's life there was some who didn 't appreciate what she was doing so decided to shot her and ended up shooting her on her forehead.
My Omi, which means grandmother in German, often tells me stories about when she was young living in Germany. As I got older, I became more curious about the many life experiences she encountered. The stories she told me were so surreal I could not even imagine living in her shoes. Her shared moments ranged from stories of her grandmother in the concentration camp to her meeting my grandfather and moving to the United States.
Ever since I was little, being on Clearfield High School drill team was always a big dream of mine since I saw them perform at multiple of their schools football and basketball games. My parents took me to my first dance class when I was three years old and ever since I fell in love with that particular sport. I was different from all of the other kids at my school because they always got to play with the other kids from school and I always ended up having dance, but I didn’t mind because that was where most of my really close friends was at my childhood dance studio. I grew really attached to everything about that studio.
100 years of JROTC: Yesterday, Today, and Tomorrow What is JROTC, or Junior Reserve Officers Training Corps? JROTC is a class that is offered for four years during high school.
Junior year was a bit challenging for me. It was not challenging because of the work, but I joined a career program. I had to keep up with both of my schools. For me to be successful with so many things going on, I had to stay organized and think ahead. My success was that I kept all my grades above a C+.
Many segregationists had told the school board that they were going to protest at Little Rock Central High School, and not allow the black students to enter the high school. Governor Orval Faubus supported the protestors and ordered the Arkansas National Guard to block off the children. On September 4, 1957, the soldiers stood in front of Little Rock Central High School, and blockaded the entire entrance. This made national headlines, and ultimately shocked the entire nation to its feet. With a furious crowd surrounding the nine students, Elizabeth Eckford said: They moved closer and closer. ...
We all remember how terrified, clueless and lost we felt during our freshman year of high school. By the time sophomore year rolls around, you have a decent amount of friends, you know where your homeroom is, and you 're pretty much used to everything the school has to offer. During my freshman year, I felt the most typical emotions a freshman would feel from starting a new school. Similarly, in the beginning of my sophomore year, I experienced some of the same emotions as a result of transferring to a new school. The ninth grade was not a great year for me academically, socially and emotionally.
Amazon is purely an online sales portal. Based on premium web rating organizations Amazon has a position ranging from 4 to 10 on a global ranking of premium websites. The presence of Amazon in the virtual world of internet is unquestionable. Big Data is a technology area which is highly talked about during the last several years. During the last 18 months, companies in the retail sector, manufacturing, construction, and technology areas have realized the extreme potential of Big Data and are trying to gain maximum advantage from it.
Even though organizations hold huge amount of data, they cannot use them effectively as they are unstructured. However new technologies are now available which enable analysis of large, complex, unstructured data. The accessibility of technology has become easy; as a result, there is massive increase in data amounts available with the entrepreneurs. The data usage depends on the ability the way it is stored, managed and then analyzing it adequately. Big data is an upcoming and emerging trend in the field of Information technology.
The firm procures raw materials and components across the world and continually examines its production requirement against its manufacturing capacities to pursue cost reduction. Capabilities Thanks to the cloud, Revlon has been able to resolve the difficulties of big-data management efficiently by classifying all the unstructured data in the company (Swan,
As big data things continue to grow in this modern era, today we can learn how to predict or assume anything that will happen in the future with data from the past. This studies known as Predictive Analytics. Predictive analytics combine methods from machine learning, data mining and statistics to find meaning or pattern from a huge volume of data. Tom H Davenport, a senior advisor at Deloitte Analytics has broken down three primer models on doing predictive analytics: the data, statistics, and assumptions.
Big Data There are many different definitions for Big Data. SAS (n.d.) an analytical software company describes it as, “a popular term used to describe the exponential growth and availability of data, both structured and unstructured.” Many think Big Data just came into existence but it has been around for years. Banks, retail, advertisers have been using big data for marketing purposes.
