Enterprise Data Warehousing and Data Mining Coursework

Enterprise Data Warehousing and Data Mining - Coursework Example To this end data mining systems are used, are they all they could be and are they really the only way of sorting the chaff from the wheat? Keywords: data, mining, search, find, information, business intelligence. Implementing Data Warehousing To bring a data warehousing system into a company means first analyzing the situation that exists, the size of the organization, its present systems and what they can do to improve the problem without extra costs, it is quite likely there are professional statisticians in the company who simply need help to get their work done a little faster. To bring a new system into the company means ensuring there is a business need as that must always drive implementation so there must be an emphasised need such as competitors are getting products to the marketplace first. Stated by Davis (1994). Once it has been decided there is no choice, but to purchase, then a study of what applications are available in the marketplace must be done, a needs definition will give information on just what is needed from the new system, it may need to be custom built or modified such as has been done for the data mining tool now used by Jaeger. Stated by Grant (2008). With a large company there are going to be many demands from different groups for something that addresses their needs, but as a person responsible for buying the tool it is important it can answer as many differing demands as possible. The implementation often means a company must upgrade its present IT, its hardware, networks and PC’s may need replacement or upgrading, so the cost of implementation becomes more than just the cost of purchasing the new system. Thearling, (2003). Figure 1: Convergence of Three Technologies for Data Mining, Thearling (2003) Once the data warehouse is in place data mining can begin, but the two things are separate, data warehousing is not data mining. For data mining to go ahead it is probable that software for this role will have to be bought, and implemented after the warehousing system is in place, creating a time delay. Applications available include: Sybase IQ 15.3 -- this business intelligence/analytics and data warehouse focused relational database management product is now powered by a so-called "new generation" of shared everything Massively Parallel Processing (MPP) technology. Bridgwater (2011). Another application is that used by Jaeger's new loss prevention programme aims to change managers' behaviour by giving them the data they need to take action. Jaeger went to UK loss prevention specialist Oris, which has a strategic partnership with product identity and shrink management company Checkpoint Systems. Oris also supplied IDM Systems' Oracle-based LossManager data mining application. Data from its electronic point of sale system lets Jaeger identify the source of losses, integrate information from other applications such as RFID and CCTV, monitor investigations, and provide action alerts for managers. "From data mining we knew that 84% of goods stolen were taken from near doors, despite 70% of our [more than 120] stores having tagging," Hearn said. Stated by Grant (2008). Benefits of a Data Warehousing System Data warehousing can be very useful in the right situation, it can give just the information needed from all

Can Feelings Have An Rational Basis Philosophy Essay

Can Feelings Have An Rational Basis Philosophy Essay Emotions are part of our everyday life, every moment of our life we are feeling an emotion, whether its happiness, sadness, fear, anger, surprise, or disgust. Emotions are expressed in three ways: 1. Emotions as an obstacle to knowledge, 2. Emotions as a source of knowledge and, 3. Intuition. Our emotions are very powerful and do have a rational basis. Emotional intelligence is not an oxymoron because with emotions we wouldnt have any intelligence. I agree with what Robert Solomon stated. He is completely correct by claiming that virtually all sense perception, and reasoning, must involve emotion. Emotions are an integral part of us and when strong enough they can sometimes distort the three other ways of knowing. Our perception of things can be colored by strong emotions, and there is doubtless some truth in sayings like love is blind and fear has many eyes. ( van de Lagemaat pg.151). This emotional coloring makes us aware of aspects of reality to the exclusion of others. For example when we love a person we think they are perfect and have no flaws as to when you loathe them you see only their faults. Our emotions can also negatively affect our reasoning causing to not have open minds. A person with powerful emotions is likely to use more emotive language. Our emotions also serve as a source of knowledge; it is difficult to live life without emotion. Our emotions help us reason through things. For example if you look down a cliff you know not to jump because you are scared and your fear helps you reason to not jump because you will die. So with what was mentioned previously w e can conclude that our feelings do have a rational basis because they help reason through things that go on during our everyday lives. Reason and emotion although are usually thought of as opposite things they are more on a continuum of some sort. Most of the time were somewhere along the middle of the continuum with our thoughts and feeling floating around our mind. For example if we are doing mathematical problems we will use less of our emotions and steer more to the other side of the continuum. Another way to think of reason and emotion is to think of our emotions being more or less rational. (van de lagemaat pg.156). The main problem with the previously mentioned idea is that sometimes our emotions are irrational such as fear and disgust. Although we know that it is safer to fly in a plane than to drive in a car most of us are terrified to get on planes. The last way emotion is a way of knowing is through intuition. The word intuition is typically associated with the aha momen t of insight when you suddenly see the solution to a problem without going through any conscious process of reasoning. (van de lagemaat pg.158) There are three types of intuition; core intuitions, subject-specific intuitions, and social intuitions. Core intuitions are our most fundamental intuitions about life, the universe and everything. For although reason and perception are usually said to give us knowledge they ultimately depend on intuition. According to core intuitions, the laws of logic are the starting point for all our reasoning, but we cannot prove them in terms of any more fundamental laws. If asked to justify them, most people would say that they are intuitively obvious. (van de lagemaat pg. 158). As for perception, it is an important source of knowledge, but we cannot be sure on the evidence of our senses alon that life is not a dream. Yet we have an overwhelmingly strong intuition that the dream hypothesis is false and that what we are experiencing is reality. A good way to explain why our knowledge is intuitive is by playing the why? game. If you were to ask a friend to claim something that she knows and then ask her why she believes that this is true and then ask her again why she believes that what she explained is true eventually she will say that it is intuitively obvious. We cant take these intuitions for granted but we cant just reject them either. As for subject specific intuition we sometimes appeal to intuition to justify our knowledge claims in various areas of knowledge. There is a wealth of evidence to suggest that our uneducated intuitions in subjects as logic, mathematics, physics, biology, history, economics and ethics are at best confused and at worst false. As for social intuitions we tend to be over confident about our own intuitions.( van de lagemaat pg 162). For example men always think they know it all and never need help in anything, we think we can fix anything and that we know how to get anywhere. The reason for this is our pride so we intuitively believe that what we think is right. As for emotional intelligence it is definitely not an oxymoron in some cases taking into account what was mentioned before. With our emotions we acquire much knowledge. Although in some cases we tend to put our pride before everything else and stop ourselves from acquiring any knowledge. Our intelligence of the world helps manipulate our emotions. We know that a cliff is tall and that jumping from heights hurts so our fear kicks in stopping us from ever attempting to jump off a cliff unless one day we find out that nothing harmful comes from jumping off a cliff. When Robert Solomon says that emotions are systems of judgments and that virtually all of our experiences is to some degree affective, and even our most dispassionate judgmentsà ¢Ã¢â€š ¬Ã‚ ¦ can be adequately understood only within some larger emotional context he basically claims that all sense perception, and reasoning, must involve emotion. I agree with this statement because everything that we do has a emotional reaction. For example if someone dies youll feel sad, if you win the lottery youll be happy, if you see a scary movie you will have fear. In other words all incoming sensory perception will have an emotional reaction. As for reason as mentioned before reason and emotion are closely related and are on the same continuum. A persons reasoning and emotions are close together but may vary depending on the task you are doing. To sum up what was previously mentioned, emotions as a way of knowing is explained in three ways: 1 as an obstacle to knowledge, 2 as a source of knowledge and, 3 as intuition. Emotions and reason are usually thought of as opposing forces when in fact they go together. Emotion and reason are on the same continuum. Without emotions we cant reason and with reason we can block emotions. It may be confusing but for example without fear how can we reason that jumping off a cliff is bad. Another thing is that with enough reason we can block emotion or come to our senses for example after we watch a scary movie we might be scared but with reason we can stop ourselves and conclude that it is impossible for what occurred in the movie to happen in real life. Emotional intelligence is not an oxymoron because with intelligence with have emotions. Finally what Robert Solomon stated makes perfect sense because without emotion how can we interpret what we perceive or how could we reason? Work cited Van de Lagemaat, Richard.

The Apaches Essay -- essays research papers

Due to the educating of the Apaches and their persistence behavior, they flourished in the Great Plains region of the US. The American Indian Tribe first got their name "Apache" from the Yuma Indians. The word Apache means "fighting men". They were hunters, farmers and seed gatherers. The Apache were known for their love of Warfare and raiding, today we would call them thieves. When the Spaniards first came to the Americas they were constantly being under attack by the Apache. The Tribe would steal the Spanish horses and eat them. They were not yet introduced to the technology of using the horse as transportation. The Apache used their dogs to help move their wickiups or homes around because they were nomadic people. Wherever the buffalo went they followed. The horse began to become transportation and no longer a meal source once the Indians watching the Spaniards ride their horses. Since the Apache loved war so much it was a surprise that they let the Spaniards on their land. The fact was the Apache let them stay on the land so that they could keep raiding them for their supplies. The persistence of the Tribe helped them make a name for themselves. (Josephy, 117) The Spanish Police began to capture and make slaves out of all the Apache trying to raid the pueblo, or town. They tried to convert the Apache to Christianity but this did not prove successful. Even though the Apache liked to steal the Spaniards supplies they eventually signed a peace treaty. (Josephy, 373) When the Spaniards were fighting with the Americans in the Mexican war the Apache were a nuisance. The Spanish troops were so busy in this war that the Apache did not have enough supplies. So they were forced to disobey the peace treaty and steal for survival. The act of breaking the peace treaty sparked warfare.(Terrell, 148) There were many branches of the Apache Indians spread across the Great Plains. They began to unite and raid near by New Mexican towns. When the tribes Apache Mimbreno and Apache Gileno united, they became the most feared groups of all the Indians. The Americans and Spaniards both did not want to get entangled into their raids of fury. This group of Indians killed more people during raids, stole more food, they were just plain out vicious Indians. The persistance of the tribe helped them make a name for themselves. The Spaniards during the Mexican w... ...ech on how honored he was to make peace with such great people, the confederates. â€Å"I am glad I have come. My heart if full of love for my pindah brothers†¦When I lie down at night the treaty will be in my heart, and when I arise in the morning it will still be there. And I will be glad I am at peace with my pindah brothers.† (Nicholas, 232) The Americans held this speech close to the hearts and they took him to his up most sincerity. On the way back from El Paso Nicholas ran off from the horses and group together his raiders. The Raiders and Nicholas rode to the Americans stock herd and stole it. They killed 2 Guards while doing so. The confederate Congress passed a law to kill all Indians spotted. Soldiers were to persuade the Apache to believe they made peace then once they had them they were to kill them. (Haley, 234) The Apache’s raiding helped keep the Americans on their toes. They flourished as a tribe despite the many different branches of them. Their aggressive behavior helped them become well known and never too weak under the rule of white men. Even though this tribe ended up with the other Indians in reservation camps, they still left a lasting impression on history.

Education †high school Essay

High school, as well as college, is just another part in everyone’s lives. Almost everyone goes through such a transition between two very diverse and different worlds. These diverse worlds can be compared and contrasted; however, not all are aware of the possible similarities and differences between them. The purpose of this essay is to compare and contrast the students in high school and students college in terms of the level of the academics, time schedule, as well as the culture practiced by each student. First of all, high school is the first step to a higher level of learning. High school equips us with the proper knowledge needed in order to survive college and other higher levels of learning. Also, there are many subjects in high school such as: math, science, English, art, piano classes and many other subjects. The students are more relaxed and they will learn more carefully. Compared to the time schedule of college students, high school students’ schedules are much more fixed because the standard call time is at 7:30 a. m. and end at 3:00p. m. Students are much more immature and they need guidance in order to lead themselves to better lives. They study inside a single classroom all day, thus having little freedom; on the other hand, the students in the college have different single rooms for each subject. College, on the other hand, is a different story. The subjects a student will learn and discuss are much more specific since students finally chose the best major and a career path students will take in the future. College students are more experience and their workload is much more complex and heavy. They have more responsibilities to carry out in college. The curriculum is much more specific and complicated because detailed topics are being discussed regarding your chosen career path. College student’s time schedules are very flexible because the students can choose their own desired time schedule. These students are much more outgoing and independent compared to high school students. The culture of college students is much more diverse because there is a huge number of students inside a college; many student come from all over the world. College introduce students to each others culture and nationality. People can really see the distinctive difference between these two phases in life; however, there are also some similarities students will experience during their transition into college live. Friends from your high school will usually be there for you especially when you keep a constant connection between them. Studying habits such as cramming for a test or homework, breaking the rules and disciplinary sanctions are still evident in both high school and college to help each other’s. To sum up, we all know that almost all students goes through high school and college. We can compare that college is much more challenging and complex than high school. This is a higher level of learning, thus, requiring more time, effort as well as devotion to studies. Even though college is very tiring at time, I still believe that college is a much more enjoyable and exciting. To have that kind of freedom in your schedule is very rewarding; however, proper judgment is a must since we are all mature students now.

Homeschooling should replace normal schooling

Homeschooling should replace normal schooling for the betterment of students in Hong Kong. Homeschooling refers to the education of children at home, typically by parents or tutors, unlike the formal settings of schools. In many countries around the world, children are not legally obligated to attend school. In England, France, Canada, the United States and Australia, it is perfectly legal for parents to educate their kids at home. Homeschooling is becoming more popular every day, with a growth rate of 7 to 15 percent per year over the world. There are about two million children currently earning at home in the world.Homeschooled kids do well on standardized tests, are welcome at college and universities, and as adults, have a reputation for being self- directed learners and reliable employees. This essay is going to examine whether homeschooling should replace normal schooling for the betterment of students in Hong Kong. Homeschooling makes children miss the golden opportunity to pr actice their social skills. School is the miniature of society. One needs to have not only knowledge of the world, but also interpersonal communication skills in order to survive, not to mention excel in a society.If a child is taught at home solely by his/ her parents, the child misses the chance to meet and interact with other kids. Peer learning has vital benefits as well. By communicating with friends, students can improve their interpersonal skills. Homeschooled children cannot take part in extra-curricular activities like debate, choir and team sports. As interactive learning is such an important component in modern education, homeschooling deprives children of their chance to develop their social skills and network, and even friends. Furthermore, home is not the most suitable environment for learning which lower he effectiveness of learning.Home cannot provide many different hardware which can only be provided by day schools. For instance, the different kinds of experiments m ust be conducted in a safety equipped and qualified laboratory . The many apparatus like Bunsen Burner, funnel and beaker can only be found in a laboratory. Home can never provide such hardware to support the diverse learning needs of children . The equipment of language labs, music room and library only appear in a school setting. Besides, there are too many temptations at home, such as television nd computer games, which would prevent children from concentrating on learning.Homeschooling undermines the development of creative thinking. Parents-to- children teaching is atter all the indoctrination ot parents thinking and values system to their children. In Hong Kong, most parents are very concerned about their children and hope them have a bright future. Therefore, they may try to give what they think is the best to the children. It is common that parents force their children to have piano lesson, choir practice, drawing class and so on in Hong Kong. Parents tend to orcefully spoon feed what they want their children to know.In many cases, children cannot develop multiple thinking perspectives. They Just do what their parents ask them to do. Their creativity and critical thinking, which are highly-valued in today's competitive world, can hardly be formed. On the other hand, it is not suitable to implement home-schooling in Hong Kong. Most parents have full time Job. They do not have time to teach their children. Moreover, parents are not professional in teaching when compared to trained teachers. They may not know how to teach their children effectively. Also, it is impossible for parents to know all knowledge of different subjects.In school, teachers are specialize in few subjects and they can concentrate on those subjects to prepare teaching materials. According to Bill and Ana Moody, who homeschool their children, they admitted that it is hard to teach science topics properly at home. They do not have sufficient knowledge of science and science requires to do experiments. Homeschooling brings another problem: how to assess the ability of students? Hong Kong is a knowledge-based society, it is important to have certificates to prove ne's academic Usually, one will get a Job easily with higher education level.Different jobs have different required education levels. If homeschooling is implemented, there is no standard to assess students unless all students Join public examinations offered by authorized organization and the Education Bureau. Homeschooling does not provide a standard to assess whether students has understand the knowledge fully. As every parents and tutors may have design a different curriculum for students, there is no standard of what basic knowledge that students should learn.Some people argued that a unified education system simply cannot cater for the individual needs of each and every student and, therefore, homeschooling is a better way for children to learn as it is more flexible which can cater individual's needs . It can provide a tailor-made learning schedule which can cater learning speed of the children and specific requirements by those who best understand them: their parents. It may allow students a more flexible combination of subjects which cater for individual needs. This would arouse interest in study, giving students the initiative to learn.However, small class teaching , which is quite popular in Hong Kong, can also cater the needs of different children. Due to the decreasing birth rate, schools started to implement small-class teaching and has smaller teacher-to student ratio. This allows teachers to pay more attention to each student in class. Flexible combination of subjects can also be achieved by new curriculum. In the past, usually students were divided into art, science and commerce classes and they were only allowed to choose subjects which are related to each other. Now, students under the new curriculum are allowed to choose subjects freely.For example, student can choo se to study Biology, a science subject, and grapny, an art subject. Some also claimed that homeschooling can enhance close family relationship. However, this may not be true. Conflicts and arguments are easily happened when parents stay with their children all the time. Parents may easily lose temper when their children are not listening to them or cannot follow their teaching schedule as they are more emotionally affected when facing their own children. Moreover, children may easily lose concentration on learning as there are too many temptations at home as mentioned before.If parents punished their children for this, the parent- child relationship would suffer. All in all, homeschooling should not replace normal schooling for the betterment of students as there are too many weaknesses of homeschooling though admitted that normal schooling has its flaws. In the current education system, students are required to study a fixed and long syllabus within a short period of time. Students study under tremendous pressure and may eventually lose interest in study. However, homeschooling neglects the social development of children which is vital in modern society.
