BEST USER SYSTEM DESIGN APPLICATION SYSTEM

INTRODUCTION
         
   An application system normally consists of a user interface, business logic and a database of some sort.


  The user interface is something that you can see and something that is used to interact with the computer.  It could consist of set of screens, web pages or reports.  Sometimes the user interface is an input device such as a bar code reader or a voice recognition device.  Some application systems don't have non-visual interfaces.  These application systems exchange data electronically with other applications via a network.

    There are many different types of computer systems.  Some application systems are small, stand-alone systems that run on a desktop computer that are used by just one individual.  Other application systems are very large and complex and can be used by hundreds of people in different geographic locations. Some countries can create a system like this that can link to their military bases

   Some application systems are centralized on a mainframe computer.  Others are distributed across multiple computers.  These “client-server” applications have software components running on client machines (e.g. presentation logic) and other components (e.g. data validation rules, data management functionality) running on one or more server machines.

  Some application systems are designed for “self-service” by customers.  These Internet and IVR applications (Interactive Voice Recognition Systems) guide infrequent or untrained users through transactions step-by-step.If such a system is design in out local supper market here giant one can buy by him/ herself 

  However, we are looking at the ease with which these systems are built and which one provide the best route for one to carry out transactions and operations. In this like, an application system that is design that even a young person or a person with basic knowledge of computer can use it conveniently is a better one.

  To remind ourselves once more of  what an application program is 

DEFINITION/EXAMPLES

   An application program (sometimes shortened to application) is any program designed to perform a specific function directly for the user or, in some cases, for another application program. Examples of application programs include word processors; database programs; Web browsers; development tools; drawing, paint, and image editing programs; and communication programs. Application programs use the services of the computer's operating system and other supporting programs. The formal requests for services and means of communicating with other programs that a programmer uses in writing an application program is called the application program interface (API).


   Therefor let us take a critical look at these systems we are conversant of  and use in everyday life situations.Lets take the case of web browsers.

  We have some many browsers that we use like Google chrome, flock, internet explorer, Mozilla Firefox, etc.
      
Having been working with these browsers, i can say from my perspective that Google chrome has the best user application system for the following reasons:
  • It offers a great dear of links on the task bar that just need just a click of the mouse and you will be able to assess your desired link
  • It provides easy assess to opening new tabs as it is easily seen by any body using this browser even if it is your first time 
  • It provide a better means to follow the activities of your friend on social networks like Facebook without necessarily going online
  • It provide notifications in case of any errors
  • Icons on the task bar are very eligible and without any ambiguity 
  • Lastly, it is fast comparatively and takes less time to execute a search .

HOW LONG CAN ONE STAY WITHOUT ACCESS TO THE INTERNET.?

QUESTION: How long can u stay without internet connection - a day, a week, a month, and or a year?

INTRODUCTION
  Permit me recount this short experience. When I was very young say 12 years old stayed and school with my dad and mum but my elder sister who was already married and working was with her husband in the city and she was responsible for my school needs while my dad wad responsible for my day to day needs. So when i needed any thing concerning my studies, i will write a letter to my elder sister via my dad. He will put the letter in his chest pocket to deliver it to my sister beside other of his businesses he needed to carry out in the city. Unfortunately for me when he returns and  i ask him  if the money or my needs were provided, that is when he is going to remember that he had a letter in his chest pocket still pending delivery meanwhile he is back - what a paradox !.
     What do i mean to say here?. With the emergence of the internet in the early 90 s, life has become more and more easier and faster relatively. Sending of information and financial transactions have been made faster and much more reliable. Just with just a click of your mouse or bottom on your handset  one can send millions of words,money, and lots more across oceans and seas, deserts and land within a twinkle of an eye. Issues like physical rubbery  forgetfulness ( as in the experience i just recounted above ) and many more uncalled actions are limited.

Now let us take a look at the major activities carried out over the internet all over the world. From research and statistical analyses ( http://www.infoplease.com/ipa/A0921860.html ) made the following report

CONCLUSION

From the above statistics it is evident that at least one can go for a couple of days with internet connection but not as much as a month talk less of a year. A world without internet connection to me is like a world of total darkness.

EFFECTS OF THE INTERNET TO MY LIFE AS A STUDENT

INTRODUCTION

This topic is similar to the previous topic of discussion in this blog. why do i say so ?. this is because if we look at this from all perspectives, we will notice that is like a two way traffic because the internet has;contributed both negatively and positively in my life as a student.

 Lets us take a look at a research carried out on this topic at Boston College and the University of Massachusetts at Lowell. According to this research,Analyzing test performance and computer uses of 986 fourth grade students from 55 classrooms in nine Massachusetts school districts, the study found that the more regularly students use computers to write papers for school, the better they performed on the Massachusetts Comprehensive Assessment Systems English/Language Arts exam. This positive effect occurred despite the fact that students were not allowed to use computers for the test.(http://www.medicalnewstoday.com/releases/19387.php).
 
 That was a research that constituted and views of many people. Let me outline the positive effects to my life as a student:

  • I do research for various assignments and sometimes get answers more quickly than using a library.
  • Equally,I send and receive email, allowing them to communicate more quickly than with postal mail
  • Also, I take coursework and related tests without needing to attend class on the class' schedule.
  • With the internet, i can interact with my school in various ways as most of announcement as course work are posted on social media like Facebook and other online campus services.
  • In the course of looking up for the solution of any assignment, it gives me a broader knowledge of related information to what at aimed at.
  • The internet has made me to have less voluminous source of information as books (hard copies) occupy much space in my room but now i have books on soft copies and very portable.
One library stored in just one notebook 



However, as i said before the internet also has it negatives effects on the life of a student and i am not left out.

  • Most often than not when ever i am connected to the internet i turn to use the social media much instead of doing my coursework. Social medias such as Facebook  Twitter  Skype and messengers turn to deviate me from studying to chatting and sharing all what not with friends
  • Also, I turn to use the abbreviations and slags i use to discus with friends in the course of writing very formal documents and when speaking with important persons and in formal places
  • The internet has made the library almost if not totally indispensable to my academic activities and by so doing has made my vocabulary not up to standard as most systems provide auto correction of spellings and limit my abilities to master the right spelling of the words 
  • Spending so much time in front of the screen has exposed me to so much radiations and liable and vulnerable to infections such as cancer 

Effects of computer radiations.

 CONCLUSION
The internet however is a very fast, reliable source of getting information for a student but then it is left for the individual to be conscious and self determine to do just that right thing at the appropriate time. One need to be very precise and self disciplined to whatever one needs to do over the internet as it has "the good, the bad and the ugly" . All-in-all, knowing what to do when connected to the internet at work time is the best way one can keep him/her self from all the tremendously numerous distractions of the internet .

ONE COMPUTER PER CHILD IDEOLOGY

  INTRODUCTION
           When i was a kid date some 20 years ago, the best punishment to be given to me for any uncalled for action was to lock me up in my room so that i will be very bored as i will have nothing to play with and that will instill some moral lessons into my brain. However, the case is not the same today as giving  a child the same punishment is like sending him to " paradise" because now he has a play station, iPad, iPod, note book, and lots more to play with. How time changes!.

ONE CHILD PER COMPUTE

     
     We are going to examine this hypothesis from two perspectives. A common saying in English goes thus,"Behind a silver lining there is a cloud", here what do i mean?. This is to say that in life everything has its own good and bad attributes. like wise the provision of a computer per child will equally have its own merits and demerits and is from here that we are going to examine the merits and demerits arising as a result of providing a child with a computer.Scientists are conducting studies on the impact of computer games in person, children argue with parents, parents – with teachers, and so on.However we are not disusing about computer games here but for the fact the it has to deal with personal computer then it is valid in here.children and computer 



MERITS/ADVANTAGES
      Almost every home, office, or school has a computer of some kind these days. It may seems at first that having a computer brings only benefits, but further consideration shows that it also has disadvantages.


First of all computers are very useful at school. It helps students to revise for tests or exams and makes subjects more interesting. Pupils can also learn new vocabulary and dramatic structures.

Furthermore it allow students to become familiar with operating a computer and gain basic computer skills.
What is more people can save a lot of time by using a computers. This is especially beneficial in the workplace where employees can do their work faster than they could in the past.

DEMERITS/DISADVANTAGES
     On the other hand, computers have creates so much negative impact as well. I tend to agree that young children can be negatively affected by too much time spent on the computer every day. This is partly because sitting in front of the screen for too long can be damaging to both the eyes and the physical posture of a young   child, regardless of what they are using the computer for.

     Well the biggest disadvantage is threats from FACEBOOK offenders and pornographic another inappropriate websites. TWITTER offenders use websites like Myspace and Facebook to lure teenagers to secret locations or they slowly figure out were the teen lives until they know for certain.

CONCLUSION.
        Providing children with computer is not a condition sine qua non that they are going to be wayward. It will on depend on the strict supervision of the children by the parents guiding the child through the right path as far as computer programs are concern. There is no way that we can escape from technological advancement, the moment we stop; then we will liable to extinction. So the best means to prevent this is to give our children access to the computer as is the backbone of all technological innovations.Childhood is the best stage in a human being's life that he can learn best because it is at this stage in life were our brains develop rapidly, metabolism highest, and we are at our apex of understanding fundamental concepts.
      

TECHNOLOGICAL ADVANCEMENT AND ITS EFFECTS ON THE SOCIETY


INTRODUCTION 

This  report aims at providing  a brief summary of some of the main technological developments that have taken place in information technology and how these developments have had an influence on the way we work and on society in general, from the 20th century. 

  Just like a baby is born been vulnerable, week, and lost more; he/ she gradually evolve from the tender stage of childhood to a matured adulthood so too is technology advancing from very primitive and rudimentary method of communication, all the attributes of technological innovations to very advanced, dynamic  and sophisticated forms. This evolution of technology can be seen from following the evolutionary trend of technology transition from the pre-mechanical , mechanical, electro-mechanical eras until the modern days electronic era. With this one is going to see the tremendous development of technological devices and lots more 

 However, here we are not talking about the history of technological innovations but longing at how these innovations have impacted our lives over the pass 40 years.

QUESTION
How has the development of information technology influenced the common traditions of a society?

INFORMATION TECHNOLOGY 

    It will be imperative for us to understand the phrase  “information technology”. Information technology is the technology used to store, manipulate, distribute or create information. The type of information or data is not important to this definition. The technology is any mechanism capable of processing this data.

    Permit me use this words by Kathleen Guinee. He  wrote, “By information technology, I mean the tools we use to perform calculations, to store and manipulate text, and to communicate. Some of these twentieth century tools include: the adding machine, slide rule, and calculator for performing calculations, the typewriter and word processor for processing text, and the telephone, radio, and television for communicating (http://www.benmeadowcroft.com/reports/impact/).

 
COMMON TRADITIONS


    Tradition can be defined as, “An inherited, established, or customary pattern of thought, action, or behavior (as a religious practice or a social custom). Cultural continuity in social attitudes, customs, and institutions.”
SOCIETY 
  The third definition is of “society”. Society can be defined as a community, nation, or broad grouping of people having common traditions, institutions, and collective activities and interests.
  We are going to examine the effects of technology on the society from three broad perspectives:
1 CULTURAL COMMUNITIES
2 INSTITUTIONS
  • Governments,
  • Commercial businesses,
  • News & Media organisations,
  • Educational organisations.

3 COLLECTIVE ACTIVITIES AND INTEREST 
  1. Work processes,
  2. Social.  
     Let us now examine the various categories 
 1 cultural communitiesSocial attitudes have changed with the effect that citizens of a society now expect the various elements of that society to be better informed than previously. They also expect to be able to access more information about a specific product, service or organisation so that they can make informed decisions with regard to their interactions with that entity.With just a phone call one can reach a friend or family member is the villages to perhaps inform them about an employment opportunity in the city at a very fast rate that even the faster alert (Usain Bolt) can not do within the allocated time.
 2 institutions
  • Government :developments in information technology has helped governments to improve their “service” to their citizens. Advances in Database technology for example have enabled the governments of various countries to collate and monitor statistical information that they can use to combat fraud, manage the economy in a more informed way.
Information Technology has also had a major impact on the defense capabilities of governments. This covers both a government’s capability to wage war and their intelligence gathering capability. Advances in weapons technology and weapons design has increased the effectiveness of various governments’ armed forces. with the help of computer programming most countries have designed faster means and weapons of fighting their enemies like the B2 Bomber . The advance of information technology has also led to a need for new legislation to be introduced, for example in the United Kingdom the Data Protection Act of 1998. The governments data protection act Web Site gives the following eight rules regarding personal information:
  1. It must be fairly and lawfully processed;
  2. Processed for limited purposes;
  3. Adequate, relevant and not excessive;
  4. Accurate;
  5. Not kept longer than necessary;
  6. Processed in accordance with the data subject’s rights;
  7. Secure;Not transferred to countries without adequate protection.(http://www.dataprotection.gov.uk/principl.htm)    


  • Commercial businesses. The most important role of information technology in a commercial business however is to provide a commercial advantage. Advances such as computer aided design, relational database technologies, spreadsheets, and word processing software all provide a commercial benefit to the business, as does automation of manufacturing processes (as Sara-Lee did in 1964).
  • News & Media organisations.Due to the nature of news and media organisations, the information technologies have particular relevance to them. As noted earlier “Information technology is the technology used to store, manipulate, distribute or create information”. News and media organisations are intimately acquainted with each of these elements of information technology. However this report will focus on the distribution and creation of information.
    Developments such as the Internet and satellite television have created new medium and audiences through which and to which these organisations can disseminate their information.
    Given the situation thirty years ago the developments that we have seen have enabled the news and media organisations access to more people, they have a wider audience. The audience however now has a wider, global choice. News reports can be received which highlight many different sides of an international conflict for example than was possible before. The relative cheapness of being able to publish information on the Internet for example means that virtually anyone can publish information accessible anywhere in the world.
  • Educational organisations. As information technology has developed over the last thirty years, educational establishments have been influenced in various ways. The most obvious example has been the introduction of information technology related courses. These courses are introduced to try to satisfy the demand that society has for qualified people to develop these information technologies.The developments that have occurred in information technology have also had other influences on educational establishments. As was discussed earlier about news and media organisations, educational organisations also have a goal to distribute information from a source (lecturer, books, on-line resources etc.) to the student. The processes by which educational establishments distribute information have become increasingly diverse, and the effectiveness of the process has also improved.  

4 collective activities and interest 

  • Work processes. Developments in information technology in the last thirty years have led from institutions with large single computers being able to only accommodate one user at a time, to a point now where powerful computing power is available to individuals rather than an organisation. Thirty years ago computers were much larger than now, often filling large rooms. The move from individuals in an organisation (whether commercial or academic) not having access to computing facilities to a position where users could have a link to computing facilities first began with Fernando Corbató’s CTSS operating system (the first multi user operating system), giving users the impression they had possession of a computer. (In fact their terminals were sharing time on the computer with other terminals).
  • Social. How has the development of information technology influenced the interactions between individuals?
    Interactions between individuals have been enhanced by the development of information technologies. New channels of communication have been opened between people in the last thirty years. These developments have been assisted by such projects as the ArpaNet. The forerunner to the Internet. The ArpaNet was commissioned as an aid to research between various institutions. This institutional use was also accompanied by an unofficial use between individuals. The ArpaNet hosted mailing lists, some of which individuals used to communicate with each other on non-institutional business. These included the science fiction mailing list (http://www.tuxedo.org/~esr/writings/hacker-history/hacker-history-2.html)
    As other developments occurred, such as the widespread availability of modems and personal computers became more widespread, the general population was integrated into what is known as the Internet.
    Individuals then have the ability to interact with other individuals through such developments as e-mail, chat-rooms and the Usenet.
    This proliferation of Internet technologies has enabled people with disabilities such as those who are blind or visually impaired, physical disabilities or others to be able to enjoy access to sources of information and ways of communicating they may not have had the opportunity to have used before.
    CONCLUSION
    The sections following that which, deal with the impact of information technology on the common traditions, institutions and the collective activities and interests provide an analysis of how the developments impacted on the general society.
    It has been shown that the developments in information technology have had an impact on general societies perception of information. Without going into specific detail about individual situations, it has been shown that that impact has been fourfold:
    1. storage,
    2. manipulation,
    3. distribution,
    4. creation.
    These four areas dealing with information are the four areas in which societies perception of information has changed. As communication and information technologies have been developed, the various elements that makeup society, whether they be individuals or organisations, expect to be able to use information in ways that were not possible thirty years ago. Society expects to be able to store more than was previously conceived. Society expects to be able to manipulate the information they have for their benefit, to increase understanding and discover new relationships. Society expects to be able to distribute information quickly, efficiently and cheaply. Society now expects the creation of new information to be facilitated by these new technologies.
