Technologies to Analyze Big Data

Technologies to Analyze Big Data Hassan, Ruman Ul Currently, most of the companies like Facebook, Google, and Amazon are generating an extensive data and this data is termed as big data. In addition to the above mentioned sources, there are many other sources like banking, airlines, stock market, and digital media that generates big data. Nandimath, Patil, Banerjee, Kakade, and Vaidya (2013) state that the volume of data being generated daily is increasing rapidly and the size of this data is nearer to zeta bytes (p. 700). This means the size of the data is increasing quickly. This data holds a value that can benefits business organizations to improve their business stability and to increase their profit. However, this big data creates the problem of storage and processing. Prior to ten years ago, the data was stored and processed in a traditional database management system. This system is called as Relational Database Management System (RDBMS). After the rise of big data, it is really difficult for the RDBMS to process this large d ata. Thus, many researchers focuse their study in developing a technology that can effectively analyze the big data. After extensive research, Google has proposed a google file system for storing the big data and a map reduce algorithm for processing this data. Moreover, Nandimath et al. (2013) assert that Apache hadoop is used for distributed processing of big data (p. 700). This framework helps many organizations in efficiently analyzing their big data. Beside Hadoop, the other technologies that help in analyzing the big data are Pig, Hive, Hbase, Zoo Keeper, and Sqoop. Each tool has their own requirements, so the usage of these tools depends on the criticality of the data and the requirement of the organization or business. However, the three major technologies to analyze big data are hadoop, hive, and pig. Hadoop is one the major technologies to analyze the big data. It is the framework developed by Apache for processing extensive data sets. This framework helps business firms to effectively process their unstructured data like video, audio and image. In addition, this framework benefits many business organizations to improve their financial stability by effectively analyzing their data. Furthermore, the hadoop framework consists of two main components, hadoop distributed file system (HDFS) and map reduce programming paradigm. The function of HDFS is to store the comprehensive datasets in distributed environment. Distributed environment allows the developer to store the large data sets on multiple machines. Thus, it helps in improving the retrieval process of immense data. In addition, Nandimath et al. (2013) state that â€Å"Hadoop uses its own file system HDFS which facilitates fast transfer of data which can sustain node failure a whole† (p. 700). It also helps developer to o vercome the storage problem. For example, if immense data is stored on a single machine then it creates a problem of processing and retrieving because of its size. Thus, if that data is distributed on multiple machines then it provide an ease for the developer for processing and retrieving. Beside fast processing and retrieving, reliability is also a benefit of HDFS. HDFS achieve high reliability by replicating the data on different machines. Therefore, if any machine fails in distributed environment, then the data of that particular machine will be easily recovered through backups. According to Dittrich and Ruiz (2012), the benefit of map reduce is that developers need to define only single functions for map and reduce task (p. 2014). This map reduce paradigm helps developers to overcome the problem of efficiently processing the data. Moreover, Nandimath et al. (2013) believe that the purpose of map is to divide the job into smaller parts and distribute it to different nodes, while the purpose of reduce is to generate the desired result (p. 701). For instance, if Facebook wants to analyze the user interest then the Facebook will first deploy the generated data on HDFS and performs the map task to divide the zeta byte of data and then perform the reduce task to get the desired result. Thus, it shows that hadoop helps organizations for efficiently analyzing their extensive datasets. Another technology to analyze big data is hive. It is a data warehouse framework build upon hadoop. It provides an ability for the developer to structure and analyze the data. In hadoop, the data processing task is performed using Java programming language where as in hive, processing a task is performed using structured query language (SQL). In addition. Borkar, Carey, and Liu (2012) assert that â€Å"Hive is SQL-inspired and reported to be used for over 90% of the Facebook map reduce use cases† (p. 2). Thus, the main goal of hive is to process the data through SQL like interface. Moreover, the traditional SQL standards were restricting the hive from performing some intensive operations like extracting, transforming and loading the big data. As a result, hive developed their own query language called hive query language (HQL). Besides traditional SQL standards, HQL includes some specific hive extensions that provide an ease for the developer to effectively analyze the big data. Furthermore, hive helps developer to overcome the scalability issue by using distributed file system mechanism. It also helps them to achieve the fast response time through HQL. For example, general SQL statements like SELECT and INSERT will consume more time on traditional database management system for big data where as in hive the same operations can be performed efficiently. Moreover, Liu, Liu, Liu, and Li (2013) conclude that with precise system parameter tuning in hive, an acceptable performance can be achieved (p. 45). This means if the developer precisely changes the system parameters for analyzing the data, then performance efficiency can be improved for that task. Besides hadoop and hive, pig is also a major technology to analyze the big data. Pig allows the developer to analyze and process the enormous datasets quickly and easily through transformation. It is also called dataflow language. The pig framework is used along with HDFS and map reduce paradigm. The working of pig is similar to that of hive except the query language. In pig a task is performed using pig latin whereas in hive, the task is performed using HQL. The main benefit of pig is that pig latin queries can be integrated with other languages like Java, Jruby, and Python and it also allow users to define their own functions to perform the task as per their needs. Moreover, as pig is a dataflow language it helps developer to illustrate the data transformation process. For example, in pig it is easy to perform the data transformation operations like Split, Stream, and Group compare to SQL. In addition, the pig framework is divided into two parts pig latin language and pig interpret er. The pig latin is a query language to process big data. In addition, Lee, Lee, Choi, Chung, and Moon (2011) assert that in pig framework a task is processed using pig latin language (p. 14). The pig latin queries help developer to process the data efficiently and quickly. Another component of pig framework is pig interpreter. The work of interpreter is to convert the pig latin queries into map reduce jobs and also to evaluate the bugs in pig latin queries. For example, if Facebook developer writes the pig latin query to find the people in India that like rock music, then this query is first interpreted by pig interpreter to identify bugs and then it is converted to map reduce jobs. Thus, with the help of pig latin queries, developers can avoid the stress of writing a tedious code in java to perform the same action. In conclusion, the three technologies to process the big data are hadoop, hive, and pig. These frameworks help business organizations to find the value from their data. In addition, each technology is useful for performing a task differently. For instance, Apache Hadoop is useful for analyzing the offline data and it cannot process the real time data like banking data. Moreover, hive provides a SQL like interface that makes the processing a lot easier because the user does not have to write the lengthy tedious code. Hive is good for those user who are not good at programming and best in SQL. Similarly, pig also makes the processing task much easier for  users. All the map reduce jobs can be written in pig latin queries to get desired results. Therefore, organizations should select the technology based on their data formats and requirements. However, all these technologies help organizations to process and store their data efficiently.

African American Musuem

Intro to Museum Studies Professor Kirsch September 19,2010 The African Museum in Philadelphia is notable as the first museum funded and built by a municipality to help preserve, interpret and exhibit the heritage of African Americans. Opened during the 1976 Bicentennial celebrations, the AAMP is located in historic Philadelphia, a few blocks away from the Liberty Bell. Charles H. Wesley was a noted African American historian, educator, and author.He was the fourth African American to receive a Ph. D. from Harvard University. An ordained minister, Wesley’s distinguished career included 40 years of leadership with the African Methodist Episcopal Church. In 1976, he served as Director of the Afro-American Historical and Cultural Museum in Philadelphia, now known as the African American Museum in Philadelphia. Programs The African American Museum that is located in Philadelphia, Pennsylvania has some interesting education programs.These education programs focus on arts, culture, a nd heritage education. They place a major emphasis on the interests of the students, educators, artists, historians, scholars, and community organizations. These programs offer diversity with scheduling. The programs explore various African forms of cultural expressions. In these programs there are literary performances, hands on demonstrations, workshops, and storytelling performances as well.The African American Museum in Philadelphia feels its programs can be a vital link between the permanent and visiting collections for the many communities they serve. Exhibitions The exhibitions in the African American Museum in Philadelphia can some to be pleasing to the eye and stimulating to the mind. According to the African American Museum of Philadelphia these exhibitions invoke a deep collection of emotion ranging from pride and passion to excitement and enthusiasm.When visitors enter the museum they will come to Gallery 1, which includes a interactive timeline, images draw from histori cal record, that spans 100 years of history. In Gallery 2 there are full size video projections in which visitors can in engage in them. Once they are activated, a monologue about life in Philadelphia will begin. Some other aspects of the exhibit include an experience where you can walk the streets of Philadelphia through a large scale map, which is located between galleries 1 and 2 .

Power in the wrong hands

Power in the Wrong Hands In Lord of The Flies by William Golding, A Tale of Two Cites by Charles Dickens, and Into Thin Air by Jon Krakauer people in power use their position to corrupt others. This suggests people should be mindful who they put In power. In these novels the authors show that no matter what age, race, social status, or even gender a person is, if given some-kind of power and competition they have the potential to become corrupt. Also, these three writings demonstrate that fear gives the ability to control people or a person.In A Tale of Two Cities by Charles Dickens, Madame Defarge knits registry of all the people who are against her and the revolution. As Madame Defarge adds names to the registry the Jacques or revolutionaries follow by her orders and kill each person on this list. Defarge states â€Å"It would be easier for the weakest of poltroon that lives, to erase himself from existence, than to erase one letter of his name or crimes from the knitted register of Madame Defarge† (Dickens 212).The more people the revolutionaries kill for Madame Defarge the more names she knits into the registry. Therefore, each time a Jacque kills a person it adds to her ower and gives her more authority over the rest of the people. Madame Defarge feeds off of and gains her power and position through installing fear into the eyes of those who are opposing to her. Now she does not only add those who are against her and are aristocrats, she knits names of those who she simply Just wants dead. Madame tells â€Å"then tell the wind and fire where to stop..But dont tell me† (Dickens 419). By the end of the novel, Madame Defarge ultimately becomes terrifying in her unwillingness to deviate from her plan of revenge against the aristocrats. In Lord of he Flies by William Golding, Jack wants nothing more than to be the absolute ruler of the island. Jack explains â€Å"Next time there will be no mercy† (Golding 31). Golding added â€Å"he looked around fiercely, daring them to contradict† (Golding 31). Jack tells that next time he will stop at nothing to prove to the rest what he is capable of.As a game all of the boys start playing that they are killing a pig; however, when the kids become overwhelmed they end up killing Simon. The boys chant â€Å"kill the beastl Cut his throat! Spill his blood! † (Golding 152). The boys chanting in the circle gradually ecome blood thirsty as they pretend to kill the â€Å"pig†. They kill Simon when he crawls Into the circle for his turn to be pig. Because Jack has a desire for blood he shows no attempt to stop the boys from tearing Simon apart.Once He killed Piggy, Jack realized that he had the ultimate power of the island. Jack then screamed â€Å"see? See? That's what you'll get! I meant thatl There Isnt a tribe for you anymorel†(Goldlng 181). Warning Ralph that he is next to die and that the hunt for him is on. It is very clear to Roger and Jack that they c an eliminate their threat, Ralph, from the island due to heir power over the tribe of choir boys. In Into Thin Air by Jon Krakauer, the leaders of the groups become corrupt as they endure fear of dying on the mountain.http://en. wikipedia. org/wiki/Into_Thin_Air https://www.slideshare.net/egalbois/the-1996-everest-tragedy-case-studyhttp://www.jonkrakauer.com/bios/jon-krakauer

Personality Disorders What Causes A Personality Disorder

Personality disorders is a deeply ingrained pattern of behavior of a specified kind, typically manifest by the time one reaches adolescence and causing long term difficulties in personal relationships or functioning in society. Someone with personality disorder not only effects the person with it but the love ones as well. A question that is always raised while talking about personality disorder is what causes a personality disorder? Some doctors and professor believe that things happen in a person’s early childhood. Then you have the scientist that feel as though it is a genetic thing. Stated in an article by MF Lenzenweger he stated that there is 9.0 to 15.7 percent of the US population has been diagnosed with personality disorder. There are numerous types of personality disorders. The more common three are Cluster a, b, and c. Inside each cluster there are disorders that fall into that category. Some quick prevalence of PPD is that 2.5% of the US have PPD. PPD lands in cluster a. The problem with personality disorders is that it doesn’t always have precise numbers nor can anybody explain how these disorders become upon individuals. Doctors and scientist both have different ways an individual can contract personality disorders. I am interested in this topic because it isn’t known as to where personality disorder comes from and to try to pinpoint it will be challenge.
