TrainAmerica Network Proposal
NTC 362
December 2, 2103

TrainAmerica Network Proposal TrainAmerica is an organization with a mission "to provide the most sought after training expertise for Microsoft products within our training area and to continue to provide excellent instructors with the experience needed to exceed the students expectations and needs (Spencer, 2013) ." To accomplish this they need to be able to implement a flexible network that can grow in a uniform manner that is easy and affordable to implement and manage, as well as being state of the art in its ability to provide services to the customer.

The Project objectives are as follows: 1. "We will install a state of the art network allowing access to the Internet from every workstation, as well as provide an infrastructure that can be used as an example for those learning how to develop superior network design. We will also be able to provide a faculty for video conferencing not only for internal use but also for our customers.

2. We will create an infrastructure so that we can provide cross site scheduling for our customers to assure classes are available when they need them.

3. We will create a sales force automation systems that will allow us to better serve our community and increase revenue at least 5%. And more efficiently service our current customers increasing customer service at least 10 %. (Spencer, 2013) "
Network requirements: * All employees to share databases. * All employees to share scheduling. * All employees to have secure company e-mail. * All employees to be able to e-mail to non-company people. * Videoconferencing for sales staff and administrators. * Administrators and sales people to have WWW access. * Remote access for employees when at home. * connections in each training room so that trainers and students can connect to the WWW. * Firewall to Internet. * Intranet in the future, if not to be part of this network.

Step 1: Problem Recognition (Concept)

Organize Preliminary thoughts: Initially the recommendation would be to design standardized networking packages to accommodate new locations by type, size, and special requirements.
For accessing the WAN to save on costs it would likely save on cost to utilize Frame Relay for our links from distant locations to the data hub because it is cheaper and more flexible.
Initially creating a data warehouse at the main branch location running RAID to provide data redundancy as well as some server redundancy should be implemented. However, as the organization grows creating a second location for redundancy may become necessary. Another option would be to pay a third party cloud service to run the servers and data management.
For locations that are geographically close to each other running fiber, or purchasing microwave LOS antennas may be more cost effective than having each connect directly to the ISP.
To manage permissions should be fairly simple by breaking departments into VLAN's so that Sales, Finance, Administrators, Support, and Training Staff each fall into their own permissions sets with what they have read or read/write access to.

Current Status Assessment:

Define the problem:

Assess the feasibility: * Cost Feasibility: * Operational Feasibility: * Technical Feasibility:

Step 2: Requirements Definition

Operational Requirements: TrainAmerica is upgrading its Microsoft Training for employees. The current systems are outdated, and need to be updated to the current operating system of Windows 8 and Office 365. Employees will need to present evidence of completion of required training. Certificates will be kept on file by the Administrators.

Program Requirements: Employees will receive basic instruction including tutorials in Microsoft Office applications (Word, Excel, PowerPoint, Access, and Outlook).Also covered will be learning Internet and email as well as online safety and basic network information

Storage Requirements: 160 GB per PC minimum or it is highly recommended be even better, in case of data loss due to natural disaster or human error. Then data recovery would be easier

Accessibility Requirements: Even though employees can share databases, user permissions, based on job function will determine what they can access and whether they have read only, or read and write, if modifications are allowed.

Speed Requirements: A computer with Intel Core Duo, or AMD 3 Ghz processor High speed connection such as T1, Broadband – LAN, DSL, or Cable

Waterfall System Development Life Cycle Final Three Stages
The Waterfall Model was the first Software Engineering development process to be used. It uses a linear sequential life cycle model for each stage of SDLC. The advantage of the Waterfall model is that it is simple and easy to use. Phases are delivered one at a time; none will overlap using this process; it is a step-by-step approach by the illustration below:

Figure [ 1 ] Waterfall SDLC for TrainAmerica

The downside of using the Waterfall Model is the system will not function until the SDLC is complete. If there is a change of requirements or if process will be lengthy, it will not work. If there are any bottlenecks, the project could easily be scrapped. (SDLC WATERFALL MODEL)

TrainAmerica management and IT staff need b to understand the importance of establishing their requirements prior to system development. Once the design process begins, no changes can be made.

Development

Implementation

Maintenance and Support
The new network is now complete and is fully functional. At this point it is important to ensure the new system is working the way it was designed and needs are being met. Routine maintenance will be performed periodically, to keep the system running efficiently. System and virus definitions are kept up-to-date as technology changes or new threats being discovered. User training will be conducted for both new employees from upper management to lower-level employees and contractors to acquaint everyone with the new system. Technical support will be included at all times, should there be any issues with the new system. Since TrainAmerica used the Waterfall Model for their system development project, correcting errors is more difficult at this stage as opposed to the Development and Implementation stages. This is not to say making corrections are not impossible, if there is a last minute change of requirements, TrainAmerica may be required to redo the entire project.

Consumersim

...Consumerism History of Consumerism Consumerism is a social and economic order that encourages the purchase of goods and services in an elevated amount. Consumerism as an ideology first appeared in Western Europe roughly three hundred years ago. It gave a rise in consumer’s need and importance to the display of material items. It promoted economic progress, a rise in small shops, an increase in the growth of cities, and an incline in individualism. A shift in the market hit right before the Industrial Revolution. Capitalist development and the industrial revolution focused on infrastructure and production and manipulation of fossil fuels. In 1919 consumerism began to sweep over the American population when General Motors Acceptance Corporation (GMAC) was established. The General Motors Acceptance Corporation mission was to issue loans to customers who had purchased a vehicle. Americans started the notion of “Keeping up with the joneses” which is the idea that Americans compare themselves to their neighbors, defining each stance in socio-cultural inferiority. With this new need for status with possessions was thought to be the beginning of the American consumer culture. Soon after The Great Depression and World War broke out. When the war-ceased consumers went wild, credit cards issued first for convince took off quickly to show status through the products each individual had. Consumerism gathered strength in the United States through internal trade growing, expansion...

Mccain Case Study

...McCain is a private company which specialize in frozen food. It's the world's largest producer of chips. McCain buys 12% of the British potato crop. As any private company, McCain has a number of objectives of which it seeks to achieve. These objectives include wining the biggest share of the market, increase sales and making profit. There are other firms that involve in the industry of frozen food, so McCain is not the only producer of chips, rather it competes with other firms to win the largest portion of market. In addition, the entry or exit from this market is not restricted. As a result, we can conclude that McCain is a competitive monopolist as it seeks to take control over this industry. In 2005, a challenging environmental factor was facing McCain. The concerns about obesity were rising dramatically, especially in children, as over 22 million children under the age of 5 and around 155 million school-age children worldwide were severely overweight.¹ McCain's view is that its chips can and do play a role in a healthy balanced diet and it is continually finding ways to ensure that its products are as healthy as possible, for example, McCain dictates product standards to the potato growers that supply them, and it may choose to have more vertical control (i.e., direct ownership) over the processing, packaging, and distribution stages of the supply chain for their french-fries because these practices may entail sophisticated production techniques that are best performed...

Body Fats

...Fats are essential for our body as human beings because it gives us energy. Everyone should know that out body needs fats in order to be healthy but some people mistake bad fats for good fats so it is important that you understand the difference. Bad fats would be fats such as Trans fats and saturated fats. Trans fats and saturated fats are bad fats because they raise you blood cholesterol concentrations, contributing to clogged arteries that block in flow of oxygen-rich blood to your heart and brain. (http://www.webmd.com/food-recipes/features/good-facts-bad-facts) Saturated fats are fats that are solid and can be found in meats, cheese and milk. Saturated facts are found majority in things like snacks, cakes and all other sweets. Saturated fats are really something that you should limit your intake on because if you eat too much you will raise your cholesterol. Tran’s fatty acids clog arteries, increase the risk for heart disease, diabetes and some cancers. Tran’s fats (Tran’s fatty acids) can be found in things that are crispy like cookies and pie crust and in foods that have partially hydrogenated oils and shortening. All fiber comes from plant origin foods such as fruits and vegetables. If you were to eat an apple you would want to eat it with the skin because that is where most of the fiber is found. Fiber cannot be digested when you eat due to the lack of specific enzymes in the body to digest them. They are found to facilitate the process of digestion and they help...

Understand Your Fats and Fibers

...According to the “Face the Fats” sections bad fats are considered saturated fats and trans fats. These fats will clog arteries and cause heart disease and heart attacks. These fats are often found in foods we enjoy to eat or that taste good. Fast food, deserts, and toppings that we place on foods are usually loaded in these types of foods. Better fats are monounsaturated fats and polyunsaturated fats. These are considered better fats due to the fact that they help reduce the risk of heart disease. Monounsaturated fats are fats that have double bonded carbon in their molecules and are usually liquid at room temperatures and become more solid when cooled or chilled. Polyunsaturated fats are fats that typically have more than one double bonded carbon in the molecule, and they are also liquid at room temperature but tend to become solid when chilled or cooled. Saturated fats are defined as fats that contain triglycerides that contain only saturated fatty acids. They can be found in foods that contain cheese, lard, or butter. Unsaturated fats are fat acids that contain double bonded chemicals that eliminate hydrogen atoms. Trans – fatty acids are usually found in man made products. They are created in an industrial process that’s adds hydrogen to liquid vegetable oils to make them solid. This type of fat can be found in most fast food products. Hydrogenated fats are found in margarine and vegetable shortenings. They are created by the forcing of hydrogen into liquid oil. They are...

Marketing

...Marketing ethics To judge a marketing activity is ethical or not, there are few areas to check. The marketing mix, known as four Ps, consists of product, price, promotion and place. For the product side, all the substantial risks of the products should be disclosed. In the points of price, it should not be too high. In the area of promotion, misleading or deceptive advertising should be avoided. In terms of place, coercion in the marketing channel should not be used. In the following essay, KFC is chosen to illustrate the topic of marketing ethics. KFC’s marketing activity Kentucky Fried Chicken (KFC) is a famous fast-food shop, which sells chicken-related food mainly. It is a multinational company. It has branch stores over the world including United Kingdom, China, Thailand, Kuwait, Spain and Pakistan. It sold over 800,000,000 chickens a year. (Smith, 2010) It succeeds in gaining such a large market share because most of the people love fried food. However, KFC provides unhealthy, even harmful foods to customers. Almost all the products contain chicken and much oil. They are not just producing junk food, but also selling toxic food to the consumers. They use oil which contains Tran’s fatty acids, which has harmful effect on human beings. It uses this kind of oil because it can raise its profits by reducing the costs. Moreover, in order to ensure adequate supply of chickens, they inject hormone into the chickens. It shortens the growing period of chickens. Each chicken...

Understanding Fats and Fiber

...There are healthy fats and unhealthy fats. Monounsaturated fats and polyunsaturated fats can lower bad cholesterol levels and are beneficial when consumed in a healthy diet. Unsaturated fats are found in oils and fish. Saturated fats and trans-fats are unhealthy fats and raise bad cholesterol levels in your blood. Saturated fats are fat molecules that have no double bonds between carbon molecules and are saturated with hydrogen molecules. Trans-fats raise bad cholesterol, and that is why trans-fats are worse than saturated fats. Trans-fats are produced in the gut of some animals and are found in foods made from these animals (e.g., milk and meat products). The beneficial fats would be monounsaturated and polyunsaturated. Monounsaturated will lower your cholesterol, but polyunsaturated will not lower your good cholesterol. Unsaturated fats are molecules that have one unsaturated carbon bond in the molecule. Olive oil is an unsaturated fat. Hydrogenated fats are considered to be trans-fats because they are mechanically created in a process by which liquid vegetable oil is turned into solid fat (Heart.org). Consuming large amounts of saturated fats can cause heart disease or stroke. Omega-3 fatty acids can benefit the heart because they decrease the risk of arrhythmias, which can lead to sudden death. Fiber absorbs cholesterol and also slows glucose absorption. Fiber is also beneficial with bowel movements and can be used to relieve mild-to-moderate diarrhea. Fiber is also beneficial...

Multiple Sclerosis Case Study Essay

...As an intern at Peak Physical Therapy, I shadow all of the PT’s, however, being a Psychological Sciences major with a concentration in neuroscience, I can’t help but interest myself in the patients that Courtney works with that are diagnosed with Multiple Sclerosis. For those of you who do not know about MS, it is a neurodegenerative disorder that destroys the myelin (fatty tissue) around the nerves, which then causes motor impairments, numbness in the limbs/extremities, Lhermitte’s symptom (an electric shock-like sensation down the spine and into the limbs) as well as other cognitive deficits. As this month’s theme is wellness, I decided to touch on how nutrition plays a role in MS patients as there is a serious lack of information and research on the effects of nutrition on MS, which presents a difficulty to a holistic approach to treatment when a serious part of the puzzle (nutrition and diet) is missing. One study in particular, Nutrition in MS, touches on how diet influences the exacerbation of MS symptoms or relief of MS symptoms. Here are some interesting points this article speculates, specifically around exacerbation/reduction in the inflammatory process of MS: Western diets (high saturated fatty acids, red meat, sweetened drinks, increased salt intake) have a significant influence on pro-inflammatory responses in the gut, which then effects the entire inflammatory response through the body (exacerbation of MS symptoms) The Mediterranean Diet–consisting of extra-virgin...

Trans Fat Research Paper

...Ban Trans-Fat! Food is commonly defined as any nutritious substance that is ingested in order to maintain life and growth. According to this definition, trans-fat should not be classified as food, but instead should be categorized as a toxic food additive. Trans-fat is commonly used in the food industry to increase product shelf life and reduce refrigeration requirements. Trans-fat promised to make food taste better, look better, last longer, and cost less, but research performed over the past several years has unequivocally demonstrated that any potential economic benefits of trans-fat come at a high cost to human health. Today’s public is rapidly gaining an understanding that trans-fat is unhealthy, and some health conscious individuals categorically...

Understand Your Fats and Fibers

...and Fiber April Willis SCI/241 July 19, 2012 Dr. Gerald Shigekawa Check Point: Understand Your Fats and Fiber There are four types of fat. Although they have similarities, such as they all supply the body with energy and they all contain 9 calories per gram, some are better than others. It is important to consume all fats in moderation because of the high calorie content. The bad fats are saturated fats and trans fats. These fats raise your cholesterol and clog arteries, therefore putting you at a higher risk for heart disease. The better fats include monounsaturated fat and polyunsaturated fat. These fats are considered better because they can actually lower the body's cholesterol level, reducing the risk for heart disease. Saturated fats have a chemical makeup where the carbon atoms are saturated with hydrogen atoms. Saturated fats are usually solid at room temperature, a stick of butter for example. Unsaturated fats are liquid at room temperature and come from a plant, such as olive, peanut, corn, cottonseed, sunflower, safflower, or soybean oil. Trans fatty acids are an unsaturated fatty acid produced by the partial hydrogenation of oils. Too much of this in the diet can raise the cholesterol level in the bloodstream. Hydrogenated fat is a fat that is semi-solid at room temperature and is found in margarine, vegetable shortening, and may processed foods. The digestive system relies on fiber to function properly and reduce the risk of disorders like constipation and...

The fats that are bad for us are saturated, and tran fats and the better fats are monounsaturated and polyunsaturated fats. Saturated fats turn solid at room temperature because they have a chemical makeup where the carbon atoms are saturated with hydrogen atoms. Trans fatty acid are fats that have been created in an industrial process that add hydrogen to liquid vegetable oils so they can become more solid. Trans fatty acids are seen on ingredient labels as “ partially hydrogenated oils”. Hydrogenated fats are considered as trans fats because these fats have been created in an industrial process. Trans-fatty acids are harmful because they raise the bad or LDL cholesterol levels and lower the HDL or good cholesterol levels in our bodies. They also increase the risk of heart disease and strokes and also have been associated with developing type 2 diabetes. Unsaturated fats are found in fish, nuts, seeds and oils from plants. Unsaturated fats are good for the body because they help lower blood cholesterol levels.

Popular Press Nutrition Claim Heart Disease Caused by Saturated Fats Disputed

...Popular Press Nutrition Claim: Heart disease is not caused by a high saturated fat intake as there has never been concrete evidence that supports the idea. Many studies have focused on the relationship between saturated fats increasing cholesterol levels and ultimately leading to heart disease. However the theory came about from the results found when giving herbivorous animals an increased amount of saturated fats in their diet (Rosch 2008). Since this theory came about from this experiment it has just been believed to be true despite the fact that it wasn’t even based off of an experiment involving humans. Such negative results can be understood to be caused by the fact that as herbivores their saturated fat intake is relatively low as they don’t consume other animal protein which contains a fair amount of saturated fat whereas most human as omnivores do. Rather than realize that the increased introduction of something that isn’t a main part of the diet in any species is bound to have negative effects the idea has been promoted by those with power that bring profit to others who help promote it (Rosch 2008). For as long as the saturated fat heart disease relationship has been studied throughout various populations around the world countless contradictions to the original theory have been found however often times such conflicting data get ignored to make the original theory appear more true than it is in reality (Rosch 2008).

The Amazingly Fat Bear

...Fat is one of the three main macronutrients: fat, carbohydrate, and protein. Fats, also known as triglycerides, are esters of three fatty acid chains and the alcohol glycerol. The terms "oil", "fat", and "lipid" are often confused. "Oil" normally refers to a fat with short or unsaturated fatty acid chains that is liquid at room temperature, while "fat" may specifically refer to fats that are solids at room temperature. "Lipid" is the general term, as a lipid is not necessarily a triglyceride. Fats, like other lipids, are generally hydrophobic, and are soluble in organic solvents and insoluble in water. Fat is an important foodstuff for many forms of life, and fats serve both structural and metabolic functions. They are necessary part of the diet of most heterotrophs . Some fatty acids that are set free by the digestion of fats are called essential because they cannot be synthesized in the body from simpler constituents. There are two essential fatty acids in human nutrition: alpha-linolenic acid and linoleic acid . Other lipids needed by the body can be synthesized from these and other fats. Fats and other lipids are broken down in the body by enzymes called lipases produced in the pancreas. Fats and oils are categorized according to the number and bonding of the carbon atoms in the aliphatic chain. Fats that are saturated fats have no double bonds between the carbons in the chain. Unsaturated fats have one or more double bonded carbons in the chain. The nomenclature is based...
