You're tasked with designing a RESTful API for a hypothetical legacy enrollment system. An description of the system is as follows A course has a department course number and title, for example, "Computer Science, 440 Software Engineering". An offering of a course specifies additional information: o o o o o The semester (Fall or Spring) and the year that the course is taught The building and room number the day(s) and time(s) of the lectures each week the instructor the maximum number of students that may enroll .Each offering has a unique ID called the course reference number (CRN) 1. Sketch a diagram (UML or ER) describing the design of such a system. 2 Sketch the RESTful routes required to support the following operations: search for course offerings by any combination of department name, instructor name and semester offered Get meeting times for a course offering Enroll a student in a course offering o o 3. Given your design, estimate the impact of a change request that would allow multiple simultaneous sections of a course to be taught in the same semester. Explain how the change may affect the schema, class interactions, how searches are handled, etc. You're tasked with designing a RESTful API for a hypothetical legacy enrollment system.
