Industry essay: What are Web Services?
Web services have been hyped over the past year to be the most
innovative improvement that has come to the Internet. It has been
adopted by many companies, and has reached the forefront of
applications development. So what is all the hype about?
Web services can be described as an application that can be deployed
or called over the Internet that allows applications to communicate
with each other- regardless of the language in which they are written
or which systems platform and operating system is being used. Each
service is a discrete unit of code, and performs a small set of given
tasks.
Typically, web services make use of standard web protocols to perform
its tasks- it usually follows an order: 1) find the web service
requested, 2) determine how the web service is called once it is
found, and 3) call the program or service requested. For the search
portion, UDDI (Universal Discovery, Description, and Integration) is
mainly used. It is a service that essentially is a directory of web
services, and UDDI helps the user find the web service or program for
which he is looking. WSDL (Web Service Definition Language) is most
often used to describe how the web service or program should be
called, and XML to communicate this. Finally, Simple Object Access
Protocol (SOAP) encodes the XML data sent and received, and shares the
data in messages over http.
The potential power of web services can be displayed in a number of
different ways. Web services are being used to integrate all sorts of
data- from local programs interfacing with each other across a local
area network, to large enterprise-level applications communicating
across the Internet. A few examples of how web services can be
utilized are listed below:
* A utility pole is damaged in a remote area of Massachusetts, and a
utility company has to come in and replace it. However, in order
to do this, the cable, telephone, and electric utility companies
have to act in a certain order in order for the damaged pole to be
removed. Web services can be used to determine the status of the
actions taken by the individual companies, since the order of the
actions is based on which utility owns the pole.
* A company wants to measure how much a particular product it has
sold, which customers bought how much of the product, when the

...partners." In other words, web services
allow the bounds on software integration to be greatly expanded. It is
now a great selling point for companies, particularly those that
develop software. And at first, those companies that develop web
services will benefit, but the success will eventually give way to
those businesses that leverage web services in the most useful manner.

Later on in the story the sprit his old dead friend and business partner, Jacob Marley, visits Scrooge in bed and warns him of the three sprits that are going to join him in the night. The first sprit to join him at 1 o'clock, the second at 2 o'clock, and the third at 3 o'clock. As the clock strikes one, the first sprit joins him, the sprit of Christmas past. He takes Scrooge back to his childhood. Scrooge sees how nice he was as a child. He also takes him back to his teenage years and shows him his old girlfriend that he was going to marry, but instead marries his one true love, money. After that experience, Scrooge is sent back to his bed to wait for two 'o clock. When that time comes a Giant comes to take him to see Christmas Present. They both go to Bob Cratchit's home to see his wife, kids, and the most special kid of all Tiny Tim. Tiny Tim is very sick and needs medical treatment, but Bob does not make enough money for that. So Tim sticks it out and still is full of Christmas sprit. As the Cratchit family sit down to Christmas dinner, which is very poor, they say a prayer, but the prayer is stopped when Bob starts to pray for his boss Scrooge. He hears how much he is hated, and asks to return to his home. He comes home to wait for the last sprit. And at 3 o'clock, the final sprit comes, the sprit of Christmas to come. He is a grim reaper type ghost, and Scrooge is very scared of him. His message is very simple. He takes Scrooge to a graveyard and shows him Cratchit standing at Tiny Tim's grave. Then he asks what shall become of me?
On page 253 Fred says “A Merry Christmas, Uncle! God save you!”. then Scrooge responds with ‘Bah! Humbug!” this proves he is grumpy because his nephew said “Merry Christmas” and Scrooge told him that he doesn't care and he needed to go away. On page 254 Scrooge says “Nephew, keep Christmas in your own way and let me keep it in mine.”. Scrooge told Fred that he was not going to celebrate Christmas with him and was trying to be nice and Scrooge told him to go away. The next reason why he is so grumpy is when he said “ If they would rather die, they had better do it and decrease the surplus population.”. There was a person collecting money for the poor. Scrooge asked if there were no prisons. The gentleman collecting money at the door said that they would rather die than go and Scrooge said that they should hurry up and do

The next day Scrooge woke up. He remembered Marley’s ghost and wondered if it was just a dream. He did remember that the next ghost would come today at one o'clock, so he decided to wait. When the clock struck one light flashed in the room and a figure drew back the curtains of his bed. The spirit like a child but at the same time an old man with long white hair from age. But did not have a single wrinkle. It was the ghost of Christmas past. He had showed Scrooge a memory of his childhood. He was a young bo...
In the story A Christmas Carol, written by Charles Dickens, Ebenezer Scrooge is given a once in a lifetime chance. After treating everyone around him with such little care, Scrooge is visited by his late employee, Jacob Marley. Marley and Scrooge have a lot in common, they are both greedy old men who only care about their money. After Marley’s death he visits Scrooge to warn him of his doomed fate and tell him that he is going to be visited by the ghosts of Christmas past, present and future. Throughout this novela, Dickens reveals the theme of compassion through the main characters loneliness, regrets and realization.
She said “ …father said you can come home… “, so it really wasn’t his choice if he could go home to his family or not, it was his father’s. But now, Scrooge is a senior citizen, he has gray hair that drapes down on the sides of his face, and he has an elongated jaw with a nose like Gru from Despicable Me. He also wore a nightgown most, if not all, of the movie. Scrooge also has a humped back and he walks with a cane around town. In addition, to how he dresses Scrooge has a very crabby personality. For example, he walks around town with a scowl printed on his face, and as he walks by carolers they stop singing! He also walks and talks about the people he passed. In his mind, if they are children they are delinquents, if they are happy they are
Scrooge is cheap and money is very important to him. From the Ghost of Christmas Past, he remembers that his fiancé broke up with him because he only had passion for his money. He is also not interested in giving money to charity. Scrooge wants the poor to go to workhouses. “I help support the prisons and the workhouses—they cost enough—and those who are badly off must go there” (7). Scrooge prefers to support workhouses rather than help people and give money to those around him. When people came to ask for charity, Scrooge “wish to be left alone” (7). Without Marley, money is all he has. After the spirits visit Scrooge, he realizes how sad and lonely his life really is. He realizes that he lost many things in his life, including his fiancé, because of his love for money. Most of all, I think he finally appreciates that happiness is worth more than money. So, when he needs help shopping, Scrooge finds a little boy, and asks, “come back with the man, and I’ll give you a schilling. Come back with him in less than five minutes and I’ll give you half a crown” (33). Scrooge realizes that it is okay to share his money. Hoarding his money made him become the miser that he is. He decides that if he gives money to other people, he will be happier. Scrooge finally opens up his heart and helps people instead of pushing them away. As the book goes on, Scrooge changes his
The spirits of all three shall strive within me! Oh Jacob Marley! Heaven, and the Christmas Time be praised for this. I say it on my knees, old Jacob, on my knees!” The text states that Scrooge was extremely flustered and definitely glowing with satisfying intentions. The text also states that he had been sobbing violently in his conflict with the spirit, and his face was wet with tears. Scrooge talks about being unquestionably happy and cheerful and he wishes a merry Christmas to all and happy New Year to everyone on Earth. Scrooge also talks about how he doesn’t know what day of the month it is and that he doesn’t know how long he had been with the spirits, he compares himself to a baby because of this. He walks down to town and sees a boy and asks him the question, what day is it. The boy replied with “ Today? Why, it’s Christmas day” Scrooge realizes that he hasn’t missed it and that the spirits have done it all in one night! Scrooge talks about the boy being very delightful and how it’s a pleasure to talk to him. According to the text, Scrooge tells the boy to go buy the immense prize turkey for him and bring it back to him and he will give him a shilling and half a crown. After the boy has taken off to buy the turkey, Scrooge says, “ I’ll send it to Bob Cratchit’s! He shan’t know who sends it. It’s twice the size of Tiny Tim. Joe Miller never made such a joke as sending it Bob’s will be!” That day, Scrooge is nice and happy to everyone he sees on his way to church. Based on what the text says, Scrooge arrives at his nephew's home after church. He asks their housekeeper where he would find him and he pokes his head into the door, his nephew, Fred, says “ Why bless my soul! Who’s there?” Scrooge replies with “ It’s I. Your uncle Scrooge. I have come to dinner. Will you let me in, Fred?” So, Fred lets
Early in the Stave we meet Fred, Scrooges nephew, who exclaims "Merry Christmas!" and stopped by the counting house to invite Scrooge to Christmas dinner. Scrooge replies with a "Bah! Humbug!" and refuses Fred's offer, clearly despising his Christmas cheer. After Fred leaves, a pair of charity workers (labelled as “Portly Gentlemen” in the text”) enters the counting house to ask Scrooge for a donation for the poor. Scrooge replies that prisons and workhouses are the only charities he supports, in which he follows up with ``If they would rather die ... they had better do it, and decrease the surplus population.” and the charity workers leave empty-handed. Scrooge then complains about Bob wanting a day off for Christmas day. "What good is Christmas ... that it should shut down business?" Scrooge eventually agrees to give Bob a day off but tells him that he must arrive at the office early the next day.
This ghost is described to be a jolly giant with dark brown curly hair who wears a fur-lined, green robe and holly wreath with shining icicles on his head. All of these qualities represent what a life lived with family and friends looks like. Scrooge does not know what this life is like because he has chosen material wealth as a false sense of happiness. As a result, his life is now dark and gloomy because he is alone. In a vision that the ghost shows Scrooge he sees Bob Cratchit, who lives on a meager salary working for Scrooge, but is still happy because he is surrounded by family. The ghost is trying to show Scrooge that money is not the path to happiness. Scrooge never enjoys himself, which is clear when you look at his living conditions, which are dark and cold constantly. After this vision, Scrooge realizes that the Ghost of Christmas Present symbolizes happiness and unity found in togetherness. Bob Cratchit is poor, but doesn’t mind it because he is happy to have his family with him. This really changes Scrooge because in the book when he finds out that Bob Cratchit has a crippled son he asks the ghost, “Tell me if Tiny Tim will live.” (Dickens Stave 3 Pg. 34) This shows that Scrooge cares about the survival of Tiny Tim, which he did not
...ps with friends and family, Scrooge exposes the emotion of joy. His feelings of joy continue on to the end of the novel where he rediscovers joy in family and the Christmas spirit. Scrooge experiences remorse when, while looking into Christmas future, he realizes how his poor actions affect others. He becomes remorseful towards Tiny Tim, his employees and the poor who he neglected. Lastly, feat was an essential emotion that Scrooge rediscovered. Scrooge’s fear towards his future and the Ghosts showed his vulnerability as a person. At the beginning of the novel, Scrooge is described as being cold hearted and lacking emotion. However, by the end of the novel, he has gone through life altering experiences that allow him to experience forgotten emotions and to change for the better.
