Systems Analysis & Design - Essay Example This paper will give details of Use Case Diagrams, Use Cases, Activity Diagram, Class Diagram, Sequence diagram and State Diagram of Caledonian Hotel System information system. Traditional information system projects were developed using the Systems Development Life Cycle (SLDC) or ‘Waterfall Model’ to manage and implement the system. Designed in the 1960s this methodology sees the process split into a series of distinct steps: Using the above ‘top-down’ process each step cannot commence until the preceding step has been completed and the findings passed down the chain, at each stage a review can take place to ensure that the requirements identified in the previous stage have been met. In recent years, this development process has come to be seen as too rigid, one of the major problems with this process is that the timescale involved from the project inception to the stage of implementation is far too long. Problems and delays at each stage of the process often result in late delivery of a system. However, a more serious problem is that because the development process is so long the final system produced can be out of date by the time it is released for use. As time passes, user requirements for a system may evolve as a company embraces new working process or technology, it is easy for these changes not to be incorporated into the system being developed and as a result, the completed system ma y not be fit for its intended purpose. To try and combat these problems new Iterative development processes have been adopted. This new iterative approach involves breaking the entire project into small ‘chunks’ based on functionality, rather than looking to deliver a complete solution one year after the project starts as the traditional waterfall process does, this iterative style will look to produce a working solution in a few months. This initial solution

Explain three (3) world arguments for birth control and two (2) world arguments against birth control - Essay Example This paper discusses some of the argument for and against birth control in how it also affects world population, the quality of life, and sustainability of subsistence supplies. The first argument against birth control is that any form of birth control is necessarily an ethical question. It means birth control is largely unethical because it is against natural law which is for any native population (human or animal) to be allowed to reproduce to full capacity. The ethics of population control goes beyond mere religion because it is a universal issue that in turn affects the very right of every living organism to be born. On the other side, Nature expectedly will cull the population to limit its growth through diseases which eliminate the sick, the weak, and the infirm. Birth control is just superfluous because Nature will take care of over-population and further, any control is dangerous as it can lead to eugenics (Chesterton & Perry, 2000). A second argument against birth control is that any form of birth control is a variation of a mass suicide. Some authors like to call it the modern version of race suicide as it eliminates the entire race or an ethnic group as its population will gradually dwindle over a period of time. The natural tendency is to let populations flourish and not allow them to perish (Parry, 2013). The first argument is birth control is much preferable compared to allowing conception that is unwanted that will in turn result into the more gruesome abortions. Many pregnancies had ended in tragedy because some females decide to terminate the gestation and this endangered the maternal health in addition to the emotional toll it exacts on the expectant mother. Many of these unwanted pregnancies are from the teenagers and young adults unable to comprehend the complexity and implications of parenthood and birth control will spare them from this agony. A second argument for birth control is it allows for a better
