/**
 * Course is a POJO, configured as a persistent class that represents (or maps to) a table
 * name 'course' in the database. A Course object contains fields that represent course
 * information and a mapping of 'courses' that indicate an inverse or referencing side
 * of the relationship. Implement Lombok annotations to eliminate boilerplate code.
