Design Activities and Environments Essay Example for Free

Design Activities and Environments Essay 1. Review the definitions of architectural and detailed design and the brief descriptions of high-level design activities at the beginning of the chapter. Which activities are clearly architectural? Which are clearly detailed? Which can be architectural or detailed? Designing the support services architecture and deployment environment and designing the software architecture are clearly architectural. Designing use case realizations and designing the database are clearly detailed. Designing the system and user interfaces and designing the system security and controls can be architectural or detailed. 2. Discuss the evolution of client-server computing from file server to multilayer applications to Web-based applications. What has been the driving force causing this evolution? Where do you think network computing will be in the next five years? Ten years? Cheaper computers, and networks, ubiquitous networking, and the desire of companies to increase the accessibility of their systems to increase the customer base/satisfaction, gain efficiencies from greater inter- and intraorganization coordination, and greater flexibility to reorganize people, processes, and systems. 3. Assume that the deployment environment for a high-volume payment processing system consists of the following: †¢ DB2 DBMS running under the OS/390 operating system on an IBM S/390 mainframe †¢ WebSphere application server running under the Z/OS operating system on an IBM zSeries 900 mainframe †¢ CORBA-compliant component-based application software written in Java that will be executed by other internal and external systems What are the key architectural design decisions that must be made for the system? When should the decisions be made and who should make them? Outline the subsequent design tasks that should occur after the key architectural design decisions are made. To what extent can the subsequent steps be performed in parallel? Some key architectural decisions to explore include: the key components and subsystems, where each component will execute and how will all of the pieces interoperate (which requires nailing down how the network, CORBA, and database infrastructure will be configured)? Many of the decisions depend on whether the supporting infrastructure is already in place. If it is, then many of the architectural decisions can be delayed until much code has been written and tested. If not, then the required infrastructure and tools will have to be acquired and configured. Developers will have to be trained, and architectural design will need to occur early to ensure that the developers don’t make any â€Å"mistakes† due to lack of fit with the development or deployment environment. Note that an OO development approach is assumed given the nature of the infrastructure and tools 4. Develop a network diagram that supports the architectural design decisions in your answer to number 2. Answers will vary. Some important points that should be included are: File servers just sent the data across the network. They tended to use lots of bandwidth, because the entire file was sent. Also, since the applications that processed the data were on all the different workstations, deployment and maintenance of these applications was expensive. Application servers moved the applications from the workstations (clients) to the server. This made it easier to maintain a consistent set of applications and to upgrade the applications. This movement was influenced by the appearance of â€Å"thin clients† that had very little storage, but good processing capability. However, due to the drastic reduction in storage costs, thin clients have not caught on. Multi-tier networks are where multiple servers and clients work together to provide the complete functionality of a system. Some processing will be on the clients. Servers such as database servers and application servers provide additional capability. The driving force behind much of this is the rapid growth and capability of the Internet and languages such as JAVA with protocols such as J2EE. Microsoft’s .NET also provides capabilities to have distributed systems. Answers for the future will vary.

Social Implications: Access to Technology Essay -- Essays Papers

Social Implications: Access to Technology Has the Internet and the computerization of work, education, and life itself lead to inequalities in the access to technology and information among people with respect to differences in race, economic classes, education, and gender? With the end of the Cold War, a newly emerging global marketplace economy aided by advancing computer and information processing technologies have rapidly changed the way people live and work. I recognize the necessity to have access to technology, and the changing need for technology over the course of a person's life. "Technological changes have outpaced ethical developments, bringing about unanticipated problems that have caused a "policy vacuum" filled by Computer Ethics, which has initially surfaced from practical concerns arising in the information society: rational decisions have to be taken, technical, educational and ethical problems must be solved, legislation needs to be adopted, and a combination of empirical evidence and logical arguments seems to provide the most obvious and promising means to achieve such pressing goals." (http://www.wolfson.ox.ac.uk/~floridi/ie.htm#1) By researching this values question, I believe that I will gain new insight and knowledge about the importance of parity in access to technology. This web site will examine if there are inequalities in the access to technology and if so how they impact our society, and discuss ways to provide solutions for equal access for people of color, underprivledged classes, educational and career purposes, and both sexes. Computer technology affects society in many ways. One needs to recognize the concerns for social responsibility in which computing technology is used.

A Person Who Has Made a Great Impact on My Life

Sometimes we come across a person who changes our whole perspective of life for better. Last summer I met Uncle Joe. My parents sent me to my uncle on holidays. I was supposed to spend my whole summer holidays with him and his family. That was the first time we have been introduced to each other. At first, I thought that it was going to be my worst holiday ever. I felt embarrassed of living with people I hardly knew and wanted to return home but days passed and I got to know my uncle better. Everyday, we used to wake up early in the morning and go for fishing.We packed our bags with provision and went to the river. He taught me how to fish and then we sat together for hours, fishing. While fishing, he used to tell a lot of interesting stories based on his own life experience. He told me stories about his student life, about his career, and about life in general. Once he asked me what I want to become and what I want to achieve in my life. I did not know what to answer  and never th ought about it before. He told me that I should  decide wisely  so that in the end I would not regret about anything I have done. I  told him  that I don't know what I want to do.Then he advised that I should do only what  I am interested in. I remember his words, he said, â€Å"Don't care about money or prestige of your occupation. Just do what you really love. † I started to list down the things which I really love and began writing them in my diary. The whole summer I spent exploring myself and finally deciding that I want to connect my future with physics and architecture. Therefore, I came to conclusion that I should study civil engineering. But this is not all what my uncle has helped me with. He also told me that I should be determined and persistent in achieving my goals.He often said that resolute determination is the truest wisdom. However, I think the most important lesson I got from my uncle is to see only positive side in any occasion. One day, we did n ot catch any fish and went home with empty hands. I looked at my uncle and noticed that he was smiling. I wondered why he was smiling as I did not see any reason to be happy. Then he said exuberantly, â€Å"We didn't catch any fish, but we had a great time. I don't see any reasons to be unhappy. † I admire his attitude. He is always grateful to everything he has and is truly happy.Uncle Joe is the person who has made an impact on my life. After that holiday, I changed my lifestyle and attitude. I used to spend a lot of time in front of my computer, playing games and surfing the net. Now, I spend more time studying, playing basketball and going out with my friends. I learned a lot of things which were new to me. I became more serious, optimistic and mature. During the time I spent with him, I also learned that no matter how smart I am or how much I know, there is always more to learn or experience. I'm grateful to him that he has helped me to find out who I am and what I want.
