Hi, need to submit a 2250 words essay on the topic Database security: Authorization and access control.

Authentication is a process through which system identifies the user. After completion of the authentication process, the process of authorization is executed, which permits the user to access required resources through which user could be identified. Authorization determines what type of resources, activities or services a user is permitted to access (Mark, 2008).

Access control refers to the system through which access to the information and services, resources is provided to the authorized entity. In computing, access control is a process which ascertains how users and systems are communicating or interacting with each other (Messaoud, 2006). ‘Entity’ is a term used in access control to start or perform computational tasks. For example, it can be the&nbsp.end user that invokes the command or the computer program, which sends instructions for performing the task. Programming task can work as a user through the diamond process (Messaoud, 2006).

Confidentiality, Integrity and Availability (CIA) is a model designed to handle policies for the information system in any organization. This model is sometimes called as the CIA triad. (Messaoud, 2006) CIA triad is a well-known mechanism for security model development and is used to develop necessary solutions for information security. CIA provides protection and secrecy of data when needed in database (Messaoud, 2006).

The term confidentiality refers to a set of rules that limit information access in a real and accurate manner. Data secrecy or confidentiality refers to prevention of unauthorized access to data. Confidentiality operation makes sure that data is delivered to the intended persons (Messaoud, 2006).

An example of confidentiality is a bank account number, which assigns an individual identity to every account holder. Data encryption is the best way for ensuring confidentiality of this type of data. Data encryption, which transforms data into code, is applied on

This report will have various segments such as the analysis of main features of business environment within the US, role of government in promoting innovation, credit facilities and resources to the firms, scientific and technological capacity of the nation as well as general analysis of the national innovation systems within the US. Discussion Science and technology has increasingly been sighted to be a direct or indirect factor influencing the living of people within US. Various features define the business environment within the US with innovation as well as job creation being the major. Sustained investments within scientific research as well as strong system of education have been commended for great influence on general economic performance of the country. However, according to a 2011-2014 public policy statement by the ACS specific policies are critical in ensuring favorable business environment. Such policy recommendations include that appropriate tax and trade policies in target of innovation and research should be adopted, encourage innovations through patenting as well as property rights and efficient commercialization and transfer of technological innovation within the country. Besides, the report shows a business environment that is in need of proper framework to encourage investment in research and innovation by small and large firms through such incentives as credit facilities and ensuring favorable business environment by the government (American Chemical Society, nd, 1-2). On the other hand, environmental awareness and conservation is a critical feature within business operations in the US where the government and other agencies increasingly regulate business operations on matters of environmental policies. According to a report by Esty and Charnovitz innovation is increasingly being influenced by policies and rules that are being adopted on environmental management and conservation. The report points to the poor performance of the government in US to implement policies that are favorable to innovation concerning the environment effectively. This has therefore been a hindrance to operations of many firms, which are dependent on environmental policy frameworks (Esty and Charnovitz, 2012, para 1-4). Other factors that continuously have a direct impact on business performances within the US are social, political as well as economic factors. The social impact on business environment in the US is emanating from such aspects as the development of social platform and media, which all business operators must be aware of. Despite the great benefits that arise from social media, equally many shortcomings result from the improper application of the media into the business world within the US. Economic influences in the business environment within US are best examined from the perspective of economic growth of the country. Political factors on the other hand come in as political set up defines policy formulations as well as legal frameworks within the nation (Sviokla and Gutstein, 2012-2013, para 1-5). Increased productivity through innovation by firms lead to improved standards of living of people.

Hi, need to submit a 2250 words essay on the topic Haas 19970.

Since the neighbors often intended to solve problems emotionally rather than rationally, it complicated the situation further still. As I gained good experience in this field through a lot of mediation, I began to conjure up creative solutions that could solve these problems from the root.

A good example of this is when one day my roommate quarreled with our neighbor for a dead rabbit in the public corridor. I not only solved the problem, but also taught them how to resolve their conflicts in a peaceful manner. During the rabbit episode, my neighbor had blamed my roommate for placing a smelly dead rabbit in the corridor, while my roommate accused him for opening her personal belongings, as the rabbit was held in her box. The heated argument led to them threatening to call the police and this is where I stepped into the picture, calmed them down and guided them to see that they both violated the other’s rights. I also told them that the best way to solve conflicts was to sort them out rationally with mutual respect for each other.

Taking my bit of advice to heart, my neighbors gradually learnt the art of reasoning and duly made use of it in times of conflict. So, when another conflict arose between my roommate and the landlord, they managed to resolve it successfully in harmony, as this time they had learnt how to resolve conflicts. Therefore, teaching people how to handle conflicts, I fulfilled my ‘Mission Impossible’!

My first impression of Berkeley was reflected through the eyes of my admirable uncle, a seasoned entrepreneur, who had rebuilt his company after the earthquake in Los Angeles in 1971. With his high recommendation due to his entrepreneurship at Berkeley, I started to carry out a critical research and consulted other Berkeley alumni. From the interaction, I found out that all the alumni were most proud and indebted to be part of such a distinguished university.

Hi, need to submit a 2250 words essay on the topic How military was the medieval castle.

Download file to see previous pages…

However, its main purpose was to house the private residence of its owner, family and dependents. The first castles were built around 1066 and were a product of medieval history during the Age of Feudalism. Feudalism refers to the military society that was created in Europe during the 9th and 10th centuries AD. The structure of feudalism resembled a pyramid. At the top was the king, who owned all the land in his kingdom. Immediately below the king was a group of major landholders that held their land directly from him, his tenants-in-chief.1 These were the lords and magnates of the kingdom. They swore to give the king military service in return for their land. They would fight for the king when and where he chose. The tenants-in-chief rented the land to their tenants, the barons and lords. This process repeated itself all the way down the pyramid to the knights, who were the local lords of the manor. The amount of land held was directly related to the amount of military service he could give the king. The first castles, called motte and bailey castles, were built of wood in the 10th and 11th centuries. They consisted of an enclosed yard called a “bailey.” Right next to that was a man made mound of dirt called a “motte.” A ditch protected the bailey and a wooden fence called a palisade.2 The palisade contained stables, workshops, and sometimes even a chapel. This was connected to the motte by a bridge. The motte was a 15 to 30 foot high structure and the main tower was built on top of it. The tower was the residence of the lord’s family, and served as a strong hold and lookout during an attack. Some early Norman castles had never been motte-and-baileys but were formidable stone castles from the start. The Tower of London and Colchester Castle are early examples, dating from the 1070s, which were conceived as defensive palaces. The Crown and the greater barons spent an enormous amount of money on castles during the third quarter of the 12th century.3 As well as being a defensive structure, castles were also offensive tools, which could be used as a base for military operations in enemy territory. Norman invaders of England established Castles for both purposes. Toward the end of the Middle Ages castles tended to lose their military significance due to modern innovations in medieval warfare. A castle could be seen as a stronghold and prison but it was also a place where the knights and lords could entertain their peers. The castles began to be designed to reflect the prestige and power of its occupants. Comfortable homes were established within the fortified walls. As time went on, castles were replaced with country houses as high status residences. However, castles were still used to provide low level protection in later periods. The first castles were constructed of timber and wood but they were very susceptible to fire, which came as a disadvantage when attacked. The main defense of a castle was its numerous walls. The walls were usually thick stone and very tall, depending on who and how it was built. The towers were built with slits so that archers could easily shoot arrows at the enemy. From the towers and alleys archers became the main defenders of the castles. Later on fire weapons were the most effective forms of castle defense. The height benefit and battlements allowed archers to fire up to 12 arrows per minute, and then take cover while the enemy fired back.

Hi, need to submit a 2250 words essay on the topic Impact of Customer Satisfaction with In-flight Catering to Airline Reputation and Profit.

This research proposal offers to explore an issue of in-flight catering and its impact to airline ratings, competitiveness, and profits of an airline. In-flight catering is one of the major services that have been associated with flights for a long time. This and other on-board services have been provided to long distance flight customers since the beginning of air passenger flights decades ago. In recent years, in-flight catering has come under increasing scrutiny by customers and the media with perceptions about meal quality being given greater attention. In most airline markets, different types of services are operated to cater for different kinds of customers. The services are largely differentiated in terms of cost and distance of flight. According to King, budget airlines and low-cost carriers offer limited on-board catering reminiscent of the flight costs of the airlines. customer expectations about catering service quality are therefore lower than in long-haul flights. Long distance flights continue to offer significant on-board services including catering, these are open to customer scrutiny with regard to quality and in-flight catering is one of the services that has clearly affected airline ratings over the years.

Customers have sometimes characterized airline food as being uninspiring and tasteless. With current competition levels it is evident that customers are increasingly taking notice of airline catering when choosing flights. this may have a bearing on airline reputation and profits over time.
