Study Of Hbase A Nonsql Database Essay - 2009 Words

Study of Hbase-A NonSql Database Abstract: With the expansion of the internet, there has been an exponential growth in the data being collected from various social media, searching patterns and online transactions. This rapid growth of data has become difficult to be handled by relational database, thus they have been replaced with NoSql databases. The NoSql databases are distributed databases that have the ability to store and process large volumes of data. This study is focused on HBase database which is a column-oriented NoSql database. HBase is Apache’s open source database that is modeled after Google’s BigTable technology. It uses Java as the API and is developed on top of the Hadoop distributed file system (HDFS) to store and process large quantities of data, maintaining reliability and fault tolerance. This database is being used by many big enterprises including Facebook, Twitter and Yahoo to store and process large quantities of data in efficient and cost effective manner. Together HBase and HDFS allow low cost hardware to be used to provide a reliable and fault tolerant data management solution that is highly scalable solution to meet the challenges of rapidly growing data efficaciously. Keywords: BigData, No Sql database, Hadoop, MapReduce, HBase, HFDS I. Introduction: The data managed on the internet has been rising exponentially. Everyday companies collect user data in large volumes from various sources like online transactions, search queries, mobile

All Of The Good And Bad Relationships That Came From The...

Almost everyone in the world wants a relationship. Someone to call their own and to be someones. Now a days, people meet each other through school or some type of social media. However, back to when Pride and Prejudice took place (between 1796 and 1813), things were a little different. A girl back then would usually meet a man through their parents and would eventually marry that man. In this essay one will learn about all of the good and bad relationships that came from the book, Pride and Prejudice. In the book the Bennets are considered and unhealthy couple. Reason is because Mr. Bennet shows no respect of love for his wife. There are many faults to this marriage, but that is the main reason. He also shows no love to her or even spend time with her, he spends most of his time in his study alone and does not want to be disturbed. â€Å"I would like to have the library to my self, as soon as maybe† (said by Mr. Bennett). I believe he seems to act sarcastically and arrogant t o his wife. The way he makes rude comments to her is not really being a true man. Marriage means that you love the person that you have giving everything to, that you need to show them the care and compassion that they need. However, when we, the people from this time period, look upon this marriage, we see it as an unhealthy and a marriage that will go down the toilet basically, but back then to that time period is was a normal and typical marriage because back then, marriage was based on money, not loveShow MoreRelated Antithetical Love in Jane Austen’s Pride and Prejudice2011 Words   |  9 PagesElizabeth Bennet and Mr. Darcy, the main characters of Jane Austen’s Pride and Prejudice, hate each other upon their first meeting but by the end of the novel are happily married.

Challenges and Decision Making

Question: Discuss about the Challenges and Decision Making. Answer: Decision-Making When it comes to effective decision making, many factors influence this activity for it to be an efficient process. From a personal point of view, making a decision involves coming up with planned changes which will make a difference in the output expected from a process (Wheelen Hunger, 2011). In this section of the analysis, a decision-making process is discussed as seen by a colleague (Henry Joe) who wanted to change the mode of communication around a busy workplace. This individual had noted that verbal communication in issuing instructions and directions to the junior staff was becoming a problem. Since the nature of operations involved in that particular firm required execution of assignments accurately, Joe noted that verbal instructions were frequently misinterpreted. Consequently, the quality of submissions made for jobs was growing very wanting from day to day operations. This prompted a change which considered consulting and researching widely to make a valid decision. After conducting several benchmarking processes of other established organisations, Joe felt that communication via email was the best channel of giving assignments and issuing instructions (Tang, 2015). During one of the regular working hours, all the staff members were called for an impromptu meeting that was meant to introduce them to the new way of communication. The decision was made to the members present a series of staff training was arranged to have the decision implemented within the quickest time frame possible (Lewis Saunders, 2012). The meeting was also meant to present the staff with a platform on which they would state their working grievances emanating from how information is relayed to them. Various concerns were presented which directly reflected the reason as to why there were numerous misunderstandings. During the implementation of the change that came with the decision, various concerns came to reality. To begin with, the IT knowledge among the workers was wanting, and this necessitated other steps to fill this loophole. Secondly, the infrastructure requires for the implementation of the decision change also required an upgrade (Slavin, 2011). However, since the execution of that change, the outcome was felt far and near around all the corners of the firm's operation. The quality of submissions from the junior staff was improved as every working team enjoyed how their responsibilities were cut down to specific instructions. Rational Decision Making Analysis From a clear point of view, it would be very genuine to note that the logical decision-making process follows a predefined model which moves the decision to be made in a couple of phases (Fleisher Bensoussan, 2014). These phases are there to ensure that the process follows a credible procedure whose consistency makes it inevitable to have a likely and reliable decision. Nevertheless, the following path describes a rational decision-making process which ideally suits the observation summarised in the decision summary section of this discussion. Objectives Formulation In rational decision making, the directive of the process is initiated by determining what goals ought to be achieved by the model in the decision expected. Similarly, before Joe contemplated on making the decision, he considered various elements and how they would suit the problem at hand on the decision he projected to make eventually. Through a personal observation, Joe's goals were to take communication in the workplace to a whole new level. The technology was supposed to form the core of the decision affecting the process. Decision Making Criteria Before making the decision, there is a certain standard that has to be adopted according to the rational decision-making model. In most cases, a decision is not something that comes overnight and implemented at the dawn of the following day. There ought to be a process that is expected to determine how the decision will be made. It was the same approach that was used by Joe in his decision making. He decided to visit established institutions' ways of communication by sampling some of the best methods that were beneficial to the involved firms (Amin, et al. 2011). It is through benchmarking that he was able to come up with a sound and firm decision. Alternatives Identification Before settling on a particular decision as the final one, the rational decision-making model suggests that one determines alternatives in a critical evaluation process. This step or phase of decision model presents an individual with choices which at times would be advantageous than a desired one (McNeil, et al. 2015). Comparatively true, Joe also made sure that he exhausted all of the alternatives that were available to him. He had even thought critically of accommodating the use of information relay via notice boards where staff members would get their instructions. Analysis After establishing that all alternatives to a decision are viable, the rational decision-making process suggests that these options undergo a review process. It is through an analysis procedure, through consulting widely with all stakeholders, that a refined decision is made (Galliers Leidner, 2014). Joe was also aware that his decision would significantly impact the organisation in its entirety. It is for this reason that he had to engage all head of departments to get their views on the new change. Meetings were held periodically to address the decision from different perspectives which formed the analysis phase of the rational decision-making process. Final Decision Making In the rational decision model, the output of this exhaustive and comprehensive procedure happens to be a refined choice. This decision was arrived at by following all the steps above before which each step must be satisfactory addressed before moving to the next one. Before considering using emails for communication within the firm, Joe had reviewed the use of destined notice boards for the same function. However, the official look of notice boards was wanting and this disqualified those channels as the principal means of communicating relevant information. That is how Joe settled on emails as the final decision (Clegg Matos, 2016). Bounded Rational Decision Making This decision-making model stipulates that a decision made by an individual is limited to time, their cognitive mind limitations and the amount of information they have. Similarly, Joe was bounded to make a decision that had randomly hit his mind due to the communication difficulties the firm was facing. On the decision steps described above, Joe was forced to come up with a refined decision basing it on the knowledge he had about it. In other terms, Joe was confined in making a decision using the information he had obtained through a series of benchmarking activities (Habermas, 2015). Through consultations, Joe was able to settle down on a decision he thought was best for the entire organisations' progress and development. One of the potential issues that Joe had to consider was the integration of technology into the firm in line with the level of communication at that particular time. To be more particular, Joe had to think how much his company had contemplated integrating technology to vital operations of the organisation. This would then prompt him to come up with alternatives that would aid the business to achieve its long desired objective as it improves on communication. The implementation would alter the way the organisation was operating. Another critical and potential issue to have bounded Joe's decision was the financial implication of executing the decision. Integrating technology for any firm would come with number economic impact. The financial stability of the business would be the ultimate determinant of the decision to be made. Fortunately, the strategy of the company to move its operations in the technology direction made it easy for Joe's decision to be accepted by the corporation. Additionally, the financial implication regarding revenue generation after successfully implementing the decision would attract the attention of the management in a positive direction. From another angle, it would also be faithful to acknowledge that Joe encountered several limitations before he succeeded in making the ultimate decision. For instance, he was periodically rejected by some firms whose internal operations felt threatened. Businesswise, no company would feel comfortable to invite an outsider into its internal operations due to unfair competition that would arise from such a scenario (Galliers Leidner, 2014). Since information is considered as a valuable weapon for any firm. This posed a significant challenge in the information-gathering phase of his decision-making quest. Some companies would reject his physical presence for fear of feeling robbed of their creativity and ideas. From another angle, the cost of making the decision (as a process) was quite huge for some reasons. For instance, Joe had to use personal resources to come up with a decision that would impact on his line of work in a positive direction. His ambitions would, in turn, motivate his efforts, and therefore, the entire cost of the decision-making process was not massively hindered by the lack of finances from the firm's end. Additionally, the cost incurred in training the staff members on using the email platform for communication came as a barrier to his decision implementation process (Robbins Judge, 2012). In conclusion, it would be important to note that any decision-making process consumes some resources. This is mostly so when a decision process has to follow the rational decision-making model (Krejewski, et al. 2013). Similarly, Joe had to sacrifice a lot of time and physical resources such as transport that was required to come up with the decision that he eventually made. Balancing his working hours and researching for the decision elements of satisfaction were quite a process which required professional insight and personal ambitions. References Amin, S.

The Adventure of The Speckled Band Essay Example

The Adventure of The Speckled Band Paper I think the reader and Holmes thinks he is capable of committing a crime as firstly the size and strength of him enable to easily overpower or extremely hurt some one. He also seems slightly apprehensive that Miss Stoner has been talking to Holmes in case he could possible get found out about something. He also has a motive as if his step-daughters were to marry, he would have to pay our i 250 to each of them, and inconveniently one of his step-daughters is shortly to marry. I think he is a stereotypical villain as he is a very big, tall being and is very angered towards Holmes and many other people. In the end Dr Grimesby Roylott succeeds in killing of his daughter by using his deadly Indian snake so he does not have to part with any of his money, however, his plan backfires and the snake turns on its owner and he is the victim of a deadly bite. In the story Watson describes Holmes as a very well dressed person with good manners and overall follows the role of typical gentlemen. He tells us of Holmes being a late riser, as a rule. This suggests Holmes gets his own way no matter what and he is very strong willed.

He also make sure he takes in every minor detail when dealing with a case to help give him the best chance of solving it and not making any mistakes, You have come by train this morning, I see whatever your reasons maybe, you are perfectly correct. I think the author wants us to see Holmes as a very intelligent and inquisitive person who is very good at his job. He is also very reassuring and comforting as shown by when Helen Stoner is in distress about her situation after telling him what has been happening, Holmes reached forward out of his chair and stroked Miss Stoners forearm. Holmes carries out his investigation carefully by visiting Helen Stoners residence personally and examining every possible cause of the crime. He is also asks lots of questions to make sure everything is clear in his mind and he is sensible and doesnt want to take any unnecessary risks as he tells Watson to slip his Revolver into his pocket as his life may depend on it. But this does suggest he his willing to endanger himself to some extent. Holmes solves the crime by way of elimination until he is satisfied that each possibility was not the cause. Holmes dominates the story as he is the main character and has a very important role as he is the one to be solving the crimes at the end of the day. Conan Doyle reflects the fact that the Police were not very good in ways of solving the many murders and other crimes that were happening at the time and therefore many people who had the money would turn to private detectives such as the likes of Holmes to get a better chance of the crime being solved. There are two main settings in the story, Holmes office and Stoke Moran. There seems to be a link between the two main characters in the story and the two main settings. Holmes office is warm and welcoming, just like him, Ha! I am glad to see Mrs Hudson has had the good sense to light the fire. This link in called pathetic fallacy, where the mood and the atmosphere compliments the scene. Stoke Moran is unlooked after, rundown and rather abandoned-looking, just like Dr Grimesby Roylott. In the text itself, these two settings are described. Firstly, Holmes office is welcoming and we can gather this from Holmes himself, who when asked by Watson what is going on, he tells of that there is a young woman waiting for him in the sitting room, this suggests that he has unhesitatingly welcomed her in and allowed her to make herself at home, we also know that he has got up early especially to meet her. Holmes office is warm and welcoming, just like him, this is suggested by Ha, I am glad Mrs Hudson has had the good sense to light the fire. This link in called pathetic fallacy, where the mood and the atmosphere this suggests Holmes has his own place well organised and he wants the best for his guests. This is back up by I shall order you a cup of coffee as I observer you are shivering, which again suggests he wants the best for his clients. On the other hand, Stoke Moran is described as the family ruin and after the past century nothing was left save a few acres of ground. It is unlooked after, rundown and rather abandoned-looking, just like Dr Grimesby Roylott. I think the settings do fit a classic story as one setting seems to be duller and gloomier (Stoke Moran) than the other (Holmes Office). This is interesting as the villain and also the crime is situated at Stoke Moran. The atmosphere in Stoke Moran is cautious and apprehensive as is the mood, this fits with the scene as the outside is dark and dreary. There seems to be a totally different atmosphere of Stoke Moran for different times of the day. When Holmes is travelling there with Watson to examine Stoke Moran, Watson tells of how delightful the surroundings on a lovely sunny day. However, when Holmes and Watson are waiting for the signal to invade Stoke Moran to carry out further investigations they are met with very dark and gloomy surrounding and are very careful to watch their step, especially as they aware of the wild animals roaming free. It is also interesting to see the contrast between travelling to Stoke Moran and arriving there. The story is put together in chronological order and in terms of when the mystery of the story is being described, which also includes some flashbacks of events from Holmes client. The story isnt too long but is longer than a typical short story as in this one there are lots of events and red herring presented as well such as when it was first thought the gypsies were to blame for the low whistle in the dead of night and also because of the fact they were bandanas. These are used to keep the reader involved and also help to create unexpected events later on. Conan Doyle uses short sentences and victims speech to build up tension, e. g. It is not cold which makes me shiver, It is fear Mr Holmes, it is terror. He uses long sentences to keep the writing flowing and the reader reading on without stopping to take in all the information. The story is narrated by Watson who is Holmes side kick, this is interesting as what he is telling us in the story is primary evidence as he is one step behind Holmes all the way, as well as we, the readers are too. We also arent in doubt about its reliability even though he does include bias positive comments on his friend, such as I had no keener pleasure than if following which were submitted to him
