What This Document Is
This document contains feedback and guidance related to Assignment 1 for CS 736: Software Performance Engineering at West Virginia University. It’s presented as a set of comments and clarifications on previously submitted work, designed to help students refine their understanding and improve their solutions. The material focuses on applying performance modeling techniques to a practical scenario – a library book checkout system. It appears to be structured as a slide presentation, offering focused commentary on specific aspects of the assignment.
Why This Document Matters
This resource is crucial for students currently working on, or those who have recently submitted, Assignment 1. It’s particularly valuable for anyone seeking to understand common areas of difficulty and how to address them. Students who want to strengthen their grasp of software execution modeling, use case diagrams, sequence diagrams, and resource assignment will find this feedback extremely helpful. Reviewing these comments *before* finalizing subsequent assignments (like Homework 3, mentioned within) can prevent repeating similar errors and improve overall performance in the course.
Common Limitations or Challenges
This document does *not* provide complete solutions to Assignment 1. It offers critiques and directions for improvement, but it’s up to the student to implement the suggested changes. It also doesn’t offer entirely new concepts; rather, it builds upon the material already introduced in the course and the initial assignment. It assumes a foundational understanding of UML diagrams and performance modeling principles. It’s also specific to the library checkout system example – the principles may apply to other scenarios, but direct application requires adaptation.
What This Document Provides
* Clarification on the correct application of modeling techniques to the assignment scenario.
* Guidance on the appropriate level of detail required in use case and sequence diagrams.
* Insights into the proper assignment of software resources within the execution model.
* Feedback on the use of delays and resource contention in the model.
* Direction on applying reduction rules for accurate performance estimation.
* Discussion of considerations for modeling alternative scenarios (e.g., unauthorized borrower IDs).
