The ABC Engineering (ABCE) has contacted you to create a conceptual model whose application will meet the expected database requirements for the company's training program. The ABCE administrator gives you the description of the training group's operating environment. ABCE has 12 instructors and can handle up to 30 trainees per class ● It offers five Advanced Technology courses, each of which may generate several classes. If a class has fewer than 10 trainees, it will be canceled.
