Step by step
Solved in 3 steps
- The overall emphasis of the __________ phase is on gathering data on the existing system, determining the requirements of the new system, considering alternatives within identified constraints, and investigating the feasibility of alternative solutions. a. investigation b. analysis c. design d. constructionSuggest an appropriate project methodology that might be used for development of the following computer systems. Provide proper justification of your choice. The traffic control system inside Riyadh city is not meeting the expectations of traffic police. The system is to be updated within a few weeks to incorporate the traffic intensity, the weather conditions and the VIP movements etc. Suggest an appropriate software model for this scenario. A social network web application (a Facebook-like application)Differentiate between Component and Deployment Diagram in the context of System Design.
- You are asked to do some requirement development. Suppose you are asked to develop a booking system for a public library system Define a possible scope for the system using the following steps. First list a wide range of things that the system could do. Then narrow down the scope by selecting the most important features that you would implement in the first release of the system. Finally, give a precise problem statement for the system. Identify stakeholders of the system. Then select one important stakeholder and design a list of questions for interviewing that stakeholder. Give functional requirements and quality requirements of the system. Create a list of use cases and describe two of them in detail using the method discussed in class (two-column method). Then draw use cases diagram to describe the system Using UML. Indicate extension, generalization and inclusion, if there are any.A gradual approach to implementing new functionality, beginning with a basic set, then adding more advanced functionality after users have had a chance to adjust to the new system is a good idea because: Group of answer choices Users can get new ideas for advanced functionality once they have a chance to use the basics of the new system. This approach allows for an iterative approach to be taken to fix issues and make improvements to the new system. It sets in motion “the journey” of continuous improvement and process redesign using the new system. All of the above.Assume that all the hardware components are available and you only need to develop a software system that controls the hardware components. Identify the actors for the system and their goals Derive only the use cases relevant to the system objective and write brief or casual text description of each Draw the use case diagram for the system For the use case that deals with the remote-controlled garage door opening, write a fully dressed description Draw the system sequence diagram(s) for the use case selected in (d) Show the operation contracts for the operations of the use case selected in (d)
- Plan-driven development is a software development method which attempts to plan and develop all of the features a usermight want in the final product and determines how all those features are to be developed. Actually this action plan is basedon the execution of an ordered set of task-specific levels.Explain any five advantages and five disadvantages of plan driven developmentA new project has an average novelty for the software supplier that is going to execute it. Development flexibility is high, and requirements may change radically. The development team is all located at the same office and the software house as a whole tends to be formal in its standards and procedures. The product should be very reliable, and the algorithms are complex. The supplier would like to reuse the project with suitable modifications on further contracts. Developers are familiar with the platform and they are capable of conducting this specific type of project. The toolsets available to the development team are judged to be typical for this size of company, but schedule pressure is tight to meet a deadline.How may heuristics be used to enhance the design of your system?
- Some techniques and approaches used during system development will need to be named and briefly described.A prototype is an initial version of a software system that is used to demonstrate concepts, try out design options, and find out more about the problem and its possible solutions. Discuss this concept in detail outlining the benefits as well as the process activities.A wide range of models are used to create software, and the relevance of each model is defined by the application being produced. Could you kindly provide a personal preference to each of these models?
