The system development life cycle framework Essay Example for Free

The system development life cycle framework Essay The system development life cycle framework provides a sequence of activities for system designers and developers to follow. It consists of a set of steps or phrases which each phase of the SDLC uses the results of the previous one. Here are some important phases that are essential for developers, Planning, Analysis, Design, and Implementation. These SDLCs are put into place and composed of clearly defined and distinct work phases. These are used by system engineers and system developers to plan for, design, build, test and deliver information systems. The product Life Cycle, is the process for building information systems in a very deliberate, structured and methodical way, originally developed for large scale functional business systems to figure out the life cycle of a program or programs. Here are the following SDLC guidelines that are used,  Preliminary analysis: The objective of phase 1 is to conduct a preliminary analysis, propose alternative solutions, describe costs and benefits and submit a preliminary plan with recommendations. Conduct the preliminary analysis: in this step, you need to find out the organizations objectives and the nature and scope of the problem under study. Even if a problem refers only to a small segment of the organization itself then you need to find out what the objectives of the organization itself are. Then you need to see how the problem being studied fits in with them. Propose alternative solutions: In digging into the organizations objectives and specific problems, you may have already covered some solutions. Alternate proposals may come from interviewing employees, clients, suppliers, and/or consultants. You can also study what competitors are doing. With this data, you will have three choices: leave the system as is, improve it, or develop a new system. Describe the costs and benefits. Systems analysis, requirements definition: Defines project goals into defined functions and operation of the intended application. Analyzes end-user information needs. Systems design: Describes desired features and operations in detail, including screen layouts, business rules, process diagrams, pseudocode and other documentation. Development: The real code is written here. Integration and testing: Brings all the pieces together into a special testing environment, then checks for errors, bugs and interoperability. Acceptance, installation, deployment: The final stage of initial development, where the software is put into production and runs actual business. Maintenance: During the maintenance stage of the SDLC, the system is assessed to ensure it does not become obsolete. This is also where changes are made to initial software. It involves continuous evaluation of the system in terms of its performance. Evaluation: Some companies do not view this as an official stage of the SDLC, but is it an important part of the life cycle. Evaluation step is an extension of the Maintenance stage, and may be referred to in some circles as Post-implementation Review. This is where the system that was developed, as well as the entire process, is evaluated. Some of the questions that need to be answered include: does the newly implemented system meet the initial business requirements and objectives? Is the system reliable and fault-tolerant? Does the system function according to the approved functional requirements? In addition to evaluating the software that was released, it is important to assess the effectiveness of the development process. If there are any aspects of the entire process, or certain stages, that management is not satisfied with, this is the time to improve. Evaluation and assessment is a difficult issue. However, the company must reflect on the process and address weaknesses. Disposal: In this phase, plans are developed for discarding system information, hardware and software in making the transition to a new system. The purpose here is to properly move, archive, discard or destroy information, hardware and software that is being replaced, in a manner that prevents any possibility of unauthorized disclosure of sensitive data. The disposal activities ensure proper migration to a new system. Particular emphasis is given to proper preservation and archival of data processed by the previous system. All of this should be done in accordance with the organizations security requirements. All of the above is necessary for proper end user design of software. If we did not have this process then systems would become obsolete and in efficient. http://csrc.nist.gov/publications/nistbul/april2009_system-development-life-cycle.pdf

Japanese Internment :: Japan War History Essays

Japanese Internment The Virtual Museum Of The City Of San Francisco has established a great source for those interested in studying the internment of Japanese during World War II. This topic is reflected very accurately and fairly in the archives of the museum because the archives consist of primary documents. Their archives of original newspaper articles are the basis of this research document. The content listed on the museum’s web site is very relevant to the topic of Japanese internment because it provides a wealth of primary documents including opinions of ordinary people writing to their newspaper to express a wide variety of viewpoints on the subject of Japanese internment during the Second World War. One question stands above all others and the virtual museum gives a good first-hand account of events to answer it - what happened to the Japanese and why were they forced to move? To answer this question, the archives of the Virtual Museum Of The City Of San Francisco should be consulted. On February 14, 1942 Lt. General J. L. DeWitt, â€Å"commanding general of the Fourth Army and the Western Defense Command[i]† recommended to the War Department, the â€Å"evacuation[ii]† of Japanese living along the Pacific coast, deemed a Military Zone. About 120,000 people of Japanese ancestry, many of those people American citizens, living on the West Coast and Southern Arizona were removed from their homes to locations of the government’s choosing. The very term â€Å"evacuation† is misleading to say the least because it suggests that the Japanese were being relocated to protect their safety. The excuses cited by the military were to establish â€Å"broad civil control, anti-sabotage, and counter-espionage measures.[iii]† The reasons given to justify â€Å"evacuation† suggested that the Japanese were a threat to the nation and not the nation a threat to the Japanese. Drawing a dichotomy, the United States Government tried to put a human face on the forced evacuations by claiming America was protecting the Japanese by moving them out of a war zone. The government would claim it was helping the Japanese by relocating the Japanese to a zone of safety outside the military zone. Statements from the government would contradict each other throughout this period of time. For instance, Japanese-Americans were termed â€Å"enemy aliens,† while at the same time, they were encouraged to be good citizens and loyal Americans by enlisting in the war effort, relocating voluntarily, offering no resistance and no questioning of the relocation efforts and activities.

A day without a mexican Essay

With the signing of the Treaty of Guadalupe-Hidalgo on February 2, 1848, the border dividing the Mexican people was formed. The Mexican border means various things to different people. To date, 600 miles of border wall has already been built. This wall would extend from California, to El Paso, to the valley. The first reason given by the government for construction of the wall was to prevent terrorist attacks, the next was to keep illegal Mexicans out, and the most current one is to combat the drug smuggling into the United States. For some Mexicans and Mexican Americans, the border poses threats, and for others, it establishes possibilities for oneself and one’s family. The border industrialization program, which began the 1970s, increased significantly from its previous conditions. Migration to border towns became highly prevalent. Border cities led to population growth and, simultaneously, high unemployment rates. In reaction, government officials started the maquilladora program. Maquillas (from the Spanish maquillar, ‘to make up’) are the giant sweatshops of the global economy, where armies of poor women are put to work to assemble goods for export. See more: Unemployment – problems and solutions essay The supply of women is so great that these women are treated with no value. Border industrialization began to rise and power companies such as Samsung and RCA, as evident in the movie, Maquilapolis (2006) by Vicky Funari and Sergio de la Torre, by always having lines of women ready and willing to work. Mexican government officials viewed the Maquiladora Program in a positive light, claiming it to be â€Å"an integral part of Mexico’s strategy for development. †[1] The movie depicts the maquiladora workers in Tijuana, Mexico to balance life working in these factories with their struggle for justice in the system that governs their place of work. This reiterates how machismo affected gender relations in Mexico and how woman are devalued. These maquiladoras are good because of the labor they give to Mexican citizens. However, it’s not fair for the low wages and cruelties taken on by the employees in these factories. Unsanitary and dangerous factory conditions pose threats to these women’s lives each day. The women are looking for the means of life and survival. They face jobless times, so they are forced to find jobs in labor. Despite the conditions these women have been subjected to, they still continue to remain hopeful. Senorita Extraviada (2001) is a documentary by Lourdes Portillo about the hundreds of unsolved murders of young women that have occurred over the past 10 years in Juarez, Mexico—the Mexican border city across the Rio Grande from El Paso. The Coalition of non-government organizations (NGOs) for Women (1994-2000) was created by female activists; their main aim behind the coalition was to change the cultural, economic, and political context of gendered violence in the city. This coalition organized events such as marches, press conferences, and domestic and international press was prevalent. There were many challenges against this coalition: it was the city’s first ever cross-class women’s political organization and the city’s first feminist-oriented political coalition. An external attack began to form on the Coalition. Many â€Å"elite† political and economic leaders argued that the violence was â€Å"normal† for Juarez. They argued that many of these women knew what they were doing—living the â€Å"doble vida† (double life) as factory workers during the day and prostitutes by night. Many asserted it was a recycled discourse of female trouble. The notion of these â€Å"public women† mimicked the negative talk surrounding the prostitutes as women who â€Å"contaminated† all associated with her from family, community, and nation. A â€Å"public woman† was regarded as an illegitimate citizen. Government authorities used this as a way to dismiss the influx of crimes and blame the women for the surge of violence in Juarez. Alejandro Lugo presents an analysis of the social dimensions along the border from color hierarchies to the notions of borderlands. He suggests that border crossings are â€Å"constituted by ‘inspection stations’ which inspect, monitor, and survey what goes in and out in the name of class, race, and nation. †[2] He asserts that the term ‘border crossings’ has become an exceedingly hopeful phrase. Lugo further claims that people are, indeed, afraid to cross these borders. There are a few reasons for that. Those who have legal residence in the U. S. , who are light-skinned, and those who speak English, cross borders without much concern. However, those are not American citizens, who are dark-skinned, and who don’t speak English face tough circumstances. As Lugo suggests, â€Å"while borderlands implies multiple sides, ‘border’ implies two sides. †[3] The division between the United States and Mexico is ever-present, separating those who are residents and those who aspire to live the American dream to better themselves and their family. Violence is being exercised against Mexicans at border crossings. The Border Patrol continues to isolate those who do not have legal residence and force these Mexicans back to where they supposedly ‘belong. ’ There is no in-between. As described by Lugo, many Border Patrol agents possess no acceptance for uncertainty. You must prove you belong or you’re forced back to the other side. This border symbolizes such positive things for many hopefuls seeking freedom, work, opportunity, however, at the same time, is a complete, unwelcoming division. Color hierarchies exhibit this discrimination against many dark-skinned Mexicans who are forced out of the U. S. by their own Mexican American people along the border. The border transforms itself. As evident of this border transformation is the drug smuggling. In a recent article, â€Å"Drug smugglers from Mexico move into NM town,† the border town of Columbus, NM has seen an influx of fancy cars with nice rims and a boom in the housing market. Many of these drug smugglers have fled from Palomas, Mexico where the Mexican army had previously been stationed. According to some residents, such as Maria Gutierrez, â€Å"The problem is in Palomas. It’s serene here†[4] Many have refused to come to terms that crime is starting to flood their town. This also alludes to the border transformation—not just a sign of hope to those who seek to cross it, but, now, a means of making big money for some. The Columbus police department has faced its share of â€Å"bad† cops within the force, yet the new appointment of police chief, Angelo Vega, is meant to restructure things within the town. However, even some residents believe that it would be impossible for this town to survive without illegal money flowing in. Not only is violence witnessed between Mexicans and Mexican Americans, but also amongst Caucasians. Racial injustice continues to exist to this day. Similar to the story of Esequiel Hernandez, the 18-year-old U. S. high school student killed on May 20, 1997 by Marines along the US–Mexico border in Redford, Texas, Luis Ramirez was recently murdered by two Anglo males in Pennsylvania. Ramirez, a 25-year-old illegal Mexican immigrant, was assaulted by â€Å"a gang of drunken white teenagers motivated by a dislike of the growing Hispanic population in their small coal town of Shenandoah. †[5] Both the Marines and the two men accused of this crime were acquitted of all charges. These types of racial tensions exhibit the racial hierarchies in society. Many guilty people can be set free just because of the color of their skin. In contrast, the story of the maquilladora program, the surge of violence along the border, gender relations, the influx of drug trading, and prevalence of racial tensions and color hierarchies amongst Mexicans and Mexican Americans all illustrate the dangers that face the border. These combinations of problems all make up the transformation of the border within the past several decades. It truly depicts the war of the frontiers. Many residents along the border, as in the town of Columbus are fighting to keep their town as it was by trying to rid the drug trafficking. Many Mexican Americans want a better life for their family, as well as, to not be treated inferiorly by their own people because of the color of their skin. As put by Salman Rushdie, â€Å"By crossing those frontiers, conquering those terrors and reaching their goal, they themselves were now what they were looking for. They had become the god they sought. †[6] For many this â€Å"god,† is the crossing at the border. For some, it leads to a life filled with promises and opportunities, and for others, false hopes and empty promises at their homeland are ever changing. The war of frontiers will continue to exist until the government does more to change how things are run along the controversial border. ———————– [1] Maria Patricia Fernandez-Kelly, â€Å"Chapter 2,† in For We are Sold, I and My People: Women and Industry in Mexico’s Frontier, (Albany: State University of New York Press, 1983), 35.

Aisha Osman. Matthew Brogden. Engl 3001W Textual Analysis

Aisha Osman Matthew Brogden Engl 3001W: Textual Analysis â€Å"Methods† March 8th, 2017 Tradition and the Individual Talent: T.S. Eliot In Tradition and the Individual Talent, T.S. Eliot makes an argument against artists expressing their own emotions and their own personal experiences to a work of art. Eliot goes into detail in how personal experiences in a work of art would essentially be pushing your own emotions on to the reader whether they want them or not. He also highlights the benefits of allowing the text to speak for itself, in a sense. Eliot believes that true art is art that can give its own emotions without the input of the author. Choosing words carefully in such a way that no personal†¦show more content†¦Ã¢â‚¬Å"(Eliot, 323). I agree with this statement because Eliot basically comes full circle to say that since there isn’t a solid definition of creative and what is true art and what is not, that art never actually improves. Century old art could not be held to the same standards as modern art not only because of the ever changing appeal of different color schemes and so on but also bec ause century old age does not have the same relevant morals and experiences as modern art. Modern art is more relatable because we may be able to understand them more than we could with older artwork. This quote also ties in with the last quote in the sense that since everyone has a different background and has a different understanding of what creativity is, or even has a different type of taste in artwork, that there is no real scale for if art is actually improving or not. There are only different types of art. T.S. Eliot then takes a drastic turn in stating that a person could never truly be an artist unless they sacrifice their personality. â€Å"The progress of an artist is a continual self-sacrifice, a continual extinction of personality.† (Eliot, 323) I disagree with this statement for more than one reason. The theory of depersonalization in a work of art takes away the humanity in that work of art. Art is a way of expressing one’s emotions, one’s creativity, and one’s message. These are the reasons people even bother making art. Art is never supposed to be
