Although Hadoop is a tool that is not indispensable but still it has a pretty bright future. It competes head on with its SQL counterparts and gives really good results on huge data.
Internet giants have been using this tool for quite some time now and surely as it advances ,which it will for sure , more and more organisations are gonna switch to Hadoop from their traditional data management tools. Also , since hadoop has various libraries/languages like
● Pig A high level platform for creating map reduce programs.
● Hive Apache Hive is a data warehouse infrastructure built on top of Hadoop for providing data summarization, query, and analysis.[1]While initially developed by Facebook, Apache Hive is now used and developed by other companies such as
Netflix.
● Pegasus Pegasus is the Graph algorithms library in Hadoop.
● HIPI HIPI is a library for Hadoop's MapReduce framework that provides an API for performing image processing tasks in a distributed computing environment. HIPI stands for Hadoop Image Processing Interface.

Kerberos provides a secure authentication scheme. Authentication is needed to restrict the intruders and malicious users. The major security issues discussed are privacy of the data, integrity of data and authentication mechanism which is not there in Hadoop. Hadoop supports Kerberos for authentication and many security features can be configured with the Hadoop to restrict the accessibility of the data. The data can be associated with the user names or group names in which data can be accessed. Kerberos is a conventional authentication system, improved authentication systems can be used which are more secure and efficient than
Utilizing the cloud and social media is a plus for any HR professional that makes their work load lighter and allows them to focus on the reason that they chose HR for a career, the people that they serve.
In the past number of years data has grown exponentially. This growth in data has created problems that and a race to better monitor, monetize, and organize it. Oracle is in the forefront of helping companies from different industries better handle this growing concern with data. Oracle provides analytical platforms and an architectural platform to provide solutions to companies. Furthermore, Oracle has provided software such as Oracle Business Intelligence Suite and Oracle Exalytics that have been instrumental in organizing and analyzing the phenomenon known as Big Data.
...now use. Majority of the world’s data is unstructured. Big data technology lets us analyze and bring together data of different types. A common theme in the data is that it is diverse. It doesn’t fall into a relational structure. Different browsers send different data; users withhold information, different forms of software versions, or vendors to communicate with you. There will be many errors and inconsistency if the process involves people. Big data is used to take unstructed data and extract ordered meaning. This is for consumption by users or it is structured input into an application.
Big Data is changing the arena for big businesses. Big Data is the technology trend that has made it possible for businesses to better understand their markets. Big Data is the new natural resource, the new “oil.”
Although big data promises better margin’s, more revenue and improvised operations it also brings new challenges to the It infrastructure which is “extreme data management” .At the same time these companies should also need to look at workload automation and make sure it is robust enough to make to handle the needs that the big data is associated to as well as the needs of the business intelligence it there to serve.
...Currently, there are no other alternatives, but since the emergence of cloud computing it has already started evolving. CIO’s Florentine suspects that cloud computing will be more software based rather than hardware based in the years to come.(Florentine, & Olavsrud, 2013).
1. Introduction In the year 2016, the size of the market for big data analytics in India was two billion USD and it is expected to grow approximately by eight times to reach around sixteen billion USD by the year 2025, as per the National Association of Software and Services Companies (NASSCOM)1. India currently ranks among the top ten big data analytics market of the world1. According to Mr. K. S. Viswanathan, Vice President, NASSCOM, the big data sector in India is expected to grow at a Compounded Annual Growth Rate (CAGR) of twenty six percent over the next five years and it will have a thirty two percent share in the global market2.
The birth of this nation was built upon the hands of individuals who came to this nation seeking a better life. It must have took a lot of courage to leave their homeland, families, and a country where for the most part was efficient and well established, but so many did to start anew. Upon arriving in this nation, it didn’t take long for the settlers to discover the abundance of resources available and to know that the abundance of resources/ goods were extremely valuable. As the states flourished, so too were the desire for specific resources, goods/ services. For this reason, this paper will explain the economic perspective of comparative/absolute advantage and how they economically impact decisions made in our nation.
You may ask what big data analytics is. Well according to SAS, the leading company in business analytics software and services describes big data analytics as “the process of examining big data to uncover hidden patterns, unknown correlations and other useful information that can be used to make better decisions.” As the goal of many companies which is to seek insights into the massive amount of structured, unstructured, and binary data at their disposal to improve business decisions and outcomes, it is evident why big data analytics is a big deal. “Big data differs from traditional data gathering due to that it captures, manages, and processes the data with low-latency. It also one or more of the listed characteristics: high volume, high velocity, or high variety. Big data comes from sensors, devices, video/audio, networks, log files, web, and social media which much of it is generated in real time and in a very large scale.”(IBM) In other words, companies moving towards big data analytics are able to see faster results but it continues to reach exceptional levels moving faster than the average person can maintain.
Big data refers to data sets with sizes beyond the ability of commonly used software tools to capture, curate, manage and process the data within a tolerable elapsed time.Big Data has vast characteristic and few of them are showed below.
A data warehouse comprised of disparate data sources enables the “single version of truth” through shared data repositories and standards and also provides access to the data that will expand frequency and depth of data analysis. Due to these reasons, data warehouse is the foundation for business intelligence.
The fascination about information management, the seminar on ‘Hadoop vs RDBMS’ as well as the exposure to data-ware housing made me realize the need of a concrete base in MIS. My long term goal is to conduct research in the field of Information Systems and I look forward to develop my career in the field of MIS and a graduate degree at University of ______, _______will be the right step in that direction.
“The Big data phenomenon is driven by staggering and energizing advances in innovation. Exploiting these advances in the agricultural division could require new hierarchical linkages to be shaped – amongst suppliers and clients and among contenders.
Technology has changed modern society drastically, both positively and negatively. Technology has influenced every aspect of our life, making it simpler but not necessarily better. Albert Einstein was concerned about the advancement of technology. "I fear the day that technology will surpass our human interaction."1 Undoubtedly, what has changed the most are communication, the spread of information, and how business is practiced. Consequently, practically everyone knows how to use a computer, connect to the Internet, or use a smartphone. This is demonstrated by the way the Internet is used daily by millions of people to communicate, to sell, advertise, retrieve, and share information. Thanks to the Internet, information from anywhere in the world is at our fingertips. As a result, the advancement of technology has changed our life in many ways including; sharing of information, communication, business, education, social interaction, simplifying everyday tasks, replacing basic skills and jobs.
