...MapReduce: Simplified Data Processing on Large Clusters Jeffrey Dean and Sanjay Ghemawat jeff@google.com, sanjay@google.com Google, Inc. Abstract MapReduce is a programming model and an associated implementation for processing and generating large data sets. Users specify a map function that processes a key/value pair to generate a set of intermediate key/value pairs, and a reduce function that merges all intermediate values associated with the same intermediate key. Many real world tasks are expressible in this model, as shown in the paper. Programs written in this functional style are automatically parallelized and executed on a large cluster of commodity machines. The run-time system takes care of the details of partitioning the input data, scheduling the program’s execution across a set of machines, handling machine failures, and managing the required inter-machine communication. This allows programmers without any experience with parallel and distributed systems to easily utilize the resources of a large distributed system. Our implementation of MapReduce runs on a large cluster of commodity machines and is highly scalable: a typical MapReduce computation processes many terabytes of data on thousands of machines. Programmers find the system easy to use: hundreds of MapReduce programs have been implemented and upwards of one thousand MapReduce jobs are executed on Google’s clusters every day. 1 Introduction Over the past five years, the authors and many others at...

...in research and routine diagnostics. However, the major hurdle is not the practical performance of the experiments themselves but rather the efficient evaluation and the mathematical and statistical analysis of the enormous amount of data gained by this technology, as these functions are not included in the software provided by the manufacturers of the detection systems. In this work, we focus on the mathematical evaluation and analysis of the data generated by real-time quantitative PCR, the calculation of the final results, the propagation of experimental variation of the measured values to the final results, and the statistical analysis. We developed a Microsoft® Excel®-based software application coded in Visual Basic for Applications, called Q-Gene, which addresses these points. Q-Gene manages and expedites the planning, performance, and evaluation of real-time quantitative PCR experiments, as well as the mathematical and statistical analysis, storage, and graphical presentation of the data. The Q-Gene software application is a tool to cope with complex realtime quantitative PCR experiments at a high-throughput scale and considerably expedites and rationalizes the experimental setup, data analysis, and data management while ensuring highest reproducibility.

Brazil’s President Dilma Rousseff consider this action a breach of international law and the Brazilian Federal Data Processing Service known as Serpro will build a secure email system for Brazil’s federal government. The statement by the Director of National Intelligence James R. Clapper said, “We collect this information for many important reasons: for one, it could provide the United States and our allies early warning of international financial crises which could negatively impact the global economy. It also could provide insight into other countries’ economic policy or behavior which could affect global markets.” Brazil over the years pursued close relationships with key U.S rivals like Iran, Venezuela, and Cuba and also because of corruption in 2007 three Petrobras executive where arrested. This will be enough reason for NSA to snoop on Brazil. Information is the key to resolved present and future issues.

...To evaluate the financial health and expected growth of Automatic Data Processing Inc., there are a few ratio analyses that can be looked at. The return on assets ratio analysis is a good indicator to see how profitable ADP Inc. is doing relative to its assets. Below is a line graph referring to the past five years of ADP’s ROA. In 2010, one can see that it started off well, but then started to decline until 2011. This occurred because there was a decline in employment as well as an increase in failed businesses (IBISWorld). After 2011 it’s percentage started to increase, as ADP better managed its assets to gain more earnings. The next ratio analysis to evaluate financial health is long-term debt to equity. Finding the long-term debt to equity ratio is important as it indicates the leverage of the firm. If the ratio is high than it is more risky which implies that there are more liabilities and less equity. As shown below, in a five-year span, the long-term debt to equity line graph looks the opposite of the one above. From 2010 to 2011 there is an increase in the ratio, which as mentioned before, there was an increase in failed businesses, causing the long-term debt to equity ratio to rise and become more risky. Fortunately, the risk decreased as ADP increased their clientele and client retention. The last ratio analysis is equally as important as the last two, as it is shows how much revenue ADP Inc. has made. The total asset turnover line graph also shows a trend of the past...

Gadekar2 1 Department of Computer Engineering, JSPM’s Imperial College of Engineering & Research, Wagholi, Pune Bhosale.harshawardhan186@gmail.com 2 Department of Computer Engineering, JSPM’s Imperial College of Engineering & Research, Wagholi, Pune devendraagadekar84@gmail.com Abstract: The term ‘Big Data’ describes innovative techniques and technologies to capture, store, distribute, manage and analyze petabyte- or larger-sized datasets with high-velocity and different structures. Big data can be structured, unstructured or semi-structured, resulting in incapability of conventional data management methods. Data is generated from various different sources and can arrive in the system at various rates. In order to process these large amounts of data in an inexpensive and efficient way, parallelism is used. Big Data is a data whose scale, diversity, and complexity require new architecture, techniques, algorithms, and analytics to manage it and extract value and hidden knowledge from it. Hadoop is the core platform for structuring Big Data, and solves the problem of making it useful for analytics purposes. Hadoop is an open source software project that enables the distributed processing of large data sets across clusters of commodity servers. It is designed to scale up from a single server to thousands of machines, with a very high degree of fault tolerance. Keywords -Big Data, Hadoop, Map...

...information. Huge amounts of raw data are produced during every operational transaction in the company. Processing raw data into valuable information allows an enterprise to take more accurate decisions into action. Information technologies give support in big business systems like (ERP) Enterprise Resource Planning, utilized in recognizing, extracting and analyzing business data, such as, sales revenue by product and/or department. Measuring data is difficult, and companies have to have complex systems for tracking ERP. Outsourcing Data With changing times, systems need to have data energy uses calculated into the core processes to retain more accurate data. Measuring impact is the recognized way in which you show the value your organization is delivering to its recipients and the general public as a whole. Often, companies feel the need to cut internal energy use; therefore, they outsource data processing duties. Businesses must be cautious when outsourcing data. This outsourcing can cause serious issues if the outsourced work is inaccurate or worse, manipulated to cause intentional damage to the company. It is difficult to have patience with outsourced companies that produce inaccurate work, as that is the main objective: they were hired to do the job proficiently and accurately. Having internal processes in place for data formulas can cut down significantly on misuse and incorrect data entry, as well as cut back on security breaches. Making sure that the data is properly reduced and...

...aAPPLICATION CONTROLS Application controls are programmed procedures designed to deal with potential exposures that threaten specific applications, such as payroll, purchases, and cash disbursements systems. Application controls fall into three broad categories: input controls, processing controls, and output controls. Input Controls Input controls at this stage are designed to ensure that these transactions are valid, accurate, and complete. Data input procedures can be either source document-triggered (batch) or direct input (real time). Source document input requires human involvement and is prone to clerical errors. Some types of errors that are entered on the source documents cannot be detected and corrected during the data input stage. Dealing with these problems may require tracing the transaction back to its source (such as contacting the customer) to correct the mistake. Direct input, on the other hand, employs real-time editing techniques to identify and correct errors immediately, thus significantly reducing the number of errors that enter the system. Classes of Input Control a. Source Document Controls. Careful control must be exercised over physical source documents in systems that use them to initiate transactions. Source document fraud can be used to remove assets from the organization. In the absence of other compensating controls to detect this type of fraud, the system would create an account payable and subsequently write a check in payment...

...Evolution In order to keep up in the global revolution of internet Amazon has created services they can provide to businesses to utilize their unused processing capacity. These services make Amazon’s infrastructure available to companies and individuals to help them run the technical and logistical parts of their businesses (Introduction to Information Systems). I believe that Amazon is moving beyond its core competency, which began as an online book retailer. Amazon has gone from selling books to also selling some electronics, such as E-Readers. With the addition of the services Amazon is now introducing, they are more able to compete with Microsoft and Google. In adding services at reasonable prices Amazon has created and implemented a sound strategy that should help to keep them in the forefront of the global internet market. The services Amazon has added so far include Simple Storage Service (S3), which allows businesses to store data and applications on Amazon disk drives, Amazon charges 15 cents per gigabyte per month. Elastic Compute Cloud (EC2) is a service in which Amazon rents out processing power starting at 10 cents per hour. Some businesses use both of these services together saving the companies both money and time. The third service Amazon has added is called Mechanical Turk, this service combines processing power with networks of people who are paid to recognize inappropriate content in images or transcribing audio. Companies post work to Mechanical Turk...

...| Internet of Things | 2014| Pragya Vaishwanar | Aricent Marketing Research Report | Summary It’s fair to say that more people have heard of the “internet of things” than have experienced it. More objects are becoming embedded with sensors and gaining the ability to communicate. The resulting information networks promise to create new business models, improve business processes, and reduce costs and risks. There is breathless press coverage of the phenomenon—always patiently re-explained by tech pundits as the trend by which all of one’s most mundane possessions will become internet-connected. These are invariably coupled with estimates that the internet of things will be a multi-trillion dollar business. 2014 is really, finally the year that the “internet of things”—that effort to remotely control every object on earth —becomes visible in one’s everyday lives. In a sense the internet of things is already with us. For one thing, anyone with a smartphone has already joined the club. The average smartphone is brimming with sensors—an accelerometer, a compass, GPS, light, sound, altimeter. It’s the prototypical internet-connected listening station, equally adept at monitoring our health, the velocity of our car, the magnitude of earthquakes and countless other things that its creators never envisioned. Yet despite repeated declarations one of the most successful sellers of baubles that help make your home “smart,” Smart-things, has only shipped 10,000 or so units since...
