Part 1,2,3 – Design and Implementation

AU Operating Systems Discussion

Part1

Design and ImplementationPrior to beginning work on this assignment, read Chapter 7: Design and Implementation. Software design and implementation is the stage in the software engineering process when an executable software system is developed. Software design and implementation shows how architectural design is put into practice when an object-oriented software design is developed.

In your initial post:

• Select five object-oriented design activities and explain the system context and the interactions use cases.
• Describe the elements of a high-level architecture and the data collection systems that are essential for the weather station.
• Describe the WeatherStation and WeatherData objects, their functions, and their interactions, using the Wilderness Weather Station example within Chapter 7.

Use at least one Scholarly, Peer Reviewed, and Other Credible Sources from the University of Arizona Global Campus Library or elsewhere to help formulate your initial discussion post. Cite your source in APA format as outlined by the APA Essay Checklist for Students. Your initial post must be a minimum of 300 words.

Part2

Software Testing

Prior to beginning work on this assignment, read Chapter 8: Software Testing. When a program or system gets implemented, it will go through a series of software tests with the intent of finding errors or defects. This is an important step of software development as it allows programmers to ensure quality and reliability of the software.

In your initial post:

• Describe an input-output model of program testing.
• Compare “Validation” versus “Verification” processes and outline the three stages of development testing.
• Describe the test-driven development (TDD) process and outline the steps in the process.
• Explain three to four benefits of using the TDD approach.

Use at least one Scholarly, Peer Reviewed, and Other Credible Sources from the University of Arizona Global Campus Library or elsewhere to help formulate your initial discussion post. Cite your source in APA format as outlined by the APA Essay Checklist for Students. Your initial post must be a minimum of 300 words.

Part3

In this week’s interactive assignment, you will add to your concept map that you created in Week 3 and further illustrate and make connections among the concepts of design and software testing. This week’s section of the concept map is focused on design and implementation and software testing. Illustrate the three major aspects of design and implementation in software engineering. Be sure to label each component, then

• Describe the software reuse at different levels and the benefits.
  • Provide an example.
• Describe the fundamental configuration management activities.
• Describe the host-target development platform.
  • Outline essential capabilities that the platform would provide.

In addition to your concept map, you will write a paper in which you

• Explain open-source development.
• Explain the considerations in leveraging open-source development.
• Provide examples of open-source software.
• Explain how software inspection can help and complement software testing.
• Explain development testing including the three stages of development testing. Include examples.
• Describe user testing, including Alpha, Beta and acceptance testing in terms of definition, participants, and methodology.

Your paper must be a minimum of 600 words.

Attach your presentation concept map and paper in your initial post. In addition, provide a brief summary of the alignment between your concept map and elements within your paper. If you choose to utilize a web-based presentation software, include the URL of your presentation in your post.
