Write a program that will take as input two Web page URLs and find a path of links from one to the other. Explain how standards may be used to capture organizational wisdom about effective methods of software development.
Suggest four types of knowledge that might be captured in organizational standards. Do you think software system can be phased out even if it is still of high quality and high business Value. Under what circumstances can that be done. Duplicate: 2. Performance and security may pose to be conflicting non-functional requirements when architecting software systems. Make an argument in support of this statement? Explain how aspect interference can arise and suggest what should be done during the system design process to reduce the problems of aspect interference.
What is social engineering? Why is it difficult to protect against it in large organizations? What are the four important attributes that all professional software should have? Suggest four other attributes that may sometimes be significant. Duplicate: What are the four important attributes that all professional software should have?
What are the four important attributes that all professional software should possess? You are a software engineering manager, and a senior member of your team proposes that model-driven engineering should be used to develop a new system In the insulin pump system, the user has to change the needle and insulin supply at regular intervals and may also change the maximum single dose and the maximum daily dose that may be administered..
In the insulin pump system, the user has to change the needle and insulin supply at regular intervals and may also change the maximum single dose and the maximum daily dose that may be administered Explain how advances in technology can force a software subsystem to undergo change or run the risk of becoming useless. Which requirements elicitation techniques are most likely to be effective in helping users and designers to create the future?
Why professional software is not just the programs that are developed for a customer, but it's for organizations and other big businesses. Consider the seven software categories: system software, application software and so on. Do you think that the same approach to software engineering can be applied for each? Explain when it may be cost-effective to use formal specification and verification in the development of safety-critical software systems.
Why do you think that critical systems engineers are against the use of formal methods? Why do you think that some critical systems engineers are against the use of formal methods?
Giving reasons for your answer based on the type of system being developed, suggest the most appropriate generic software process model that might be used to develop a system that automatically controls the speed of a motor vehicle cruise control.
Choose any piece of software which you use regularly. Briefly describe the requirements that the software meets for you as the user. Suggest three ways in which the software could be improve for you.

I'd like to write like this too - taking time and real hard work to make a great article Thanks though. This particular is usually apparently essential and moreover outstanding truth along with for sure fair-minded and moreover admittedly useful My business is looking to find in advance designed for this specific useful stuffs… Agile software development.
Thank you because you have been willing to share information with us. You will find a lot of approaches after visiting your post. I was exactly searching for.
Thanks for such post and please keep it up. Great work. Software development sector is always changing and evolving. The software industry must stay one step ahead to tackle the increasing challenges that will arise in the future. In this article, we'll explore some of the problems and challenges the software engineering industry might face in the 21st century. Really I enjoy your site with effective and useful information. It is included very nice post with a lot of our resources.
When the body senses something is not part of itself, it attacks it. We build computers with no inherent immune system, and our antivirus software is a set of hacks that checks for specific files after a human has decided what to look for. This problem asks researchers to design a system with inherent immunity. The problem then is the same as for transplants: How to circumvent the immune system to allow transplants.
General Statement: Construct a language, system or environment in which the goals and global, or emergent, properties of a population may be expressed, and which produces or assists implementing a set of local behavior or rules that exhibit the specified properties. Specific Statement: In order to move toward a general approach to solving this problem, we pose the following specific problem: Design and implement a formal language capable of expressing the properties of a flock of simulated birds whose goals and global, or emergent, properties are as follows:.
Construct a formal language to state these properties and a system or environment that is able to propose a set of local behaviors or rules that, when executed individually by a population of entities, exhibits these properties. Extend this system to handle the addition of these global properties associated with predators on the birds, where each predator continuously attempts to collide with a bird.
Explanation: In complex systems on the edge of chaos , you see global properties emerge from simple local rules. So with a flock of birds, each bird follows these rules:. In general, one programs these systems by thinking up these rules and then watching the global behavior to see whether you got the ones you wanted.
This Feyerabend problem turns that around: Tell the system the global behavior and it will help you find the rules. This is important because if you wanted to program a swarm of agents to help keep a system healthy, for example, you'd want to specify global characteristics, not local ones.
