The Student Information System Requirements Definitions (SISRD) document is the requirements definition document of a new software product that keeps track of both student and course records for educational institutions. The goal of this software product is to maintain and track information about students in the educational institution and the courses offered by the institution. The users of the system are the staff of the institution. You are hired as a consultant software architect to design a use case diagram for this system. Analyze the Courses and Classes Records System Requirements Definitions document and formalize them as use cases. Generate a use case diagram showing the actors associated with each use case and structure your use cases using include,extend, and generalization relationships, if applicable. The use case diagram must be generated by a UML drawing tool. Links to Unified Modeling Language (UML) drawing tools are found in the syllabus and in the Required Resources for Module One. After creating your model, make sure to submit all of the following deliverables:

• A use case diagram
• Verification and validation of your work
• An explanation of your work and how you arrived at your solution
• A reflection on your learning experience and lesson learned
