Database Assignment

(Assignment 2)

Table 1 (Identify PK and FK Relationships)

Table Name

COURSE

TRAINING

Primary Key

Course ID

Trainee ID

Foreign Key

Course_ID

Pk of TRAINING table is a combination of (trinee_ID and course_ID)

there is no FK in COURSE table. FK in TRIAING table is COURSE_ID which is pointing to Pk in COURSE table

grade=-2

I believe that the relationship shared is considered to be one to one. The Course ID from the Course table links to the other table Trainee through the Course_ID.

No..it is 1:m; justification:

a course can be part of many training session and a training session belongs to one course
