Introduction A relational database has been created using MySQL to store details about students' performance. There are four tables in the database: Student, Course, Assessment, and Grade. A student takes one or more courses. A course may be assessed by coursework assessments and exam. The name and weighting of each assessment component are stored in the Assessment table. Students' marks on their assessments are recorded in the Grade table. An Entity-Relationship model of the database is shown below: Assessment Course 1..1 1.* aid {PK} cid {PK} has > cid {FK} title name weighting 1.1 records 1.* Student Grade sid {PK} 1.* sid {PK, FK} aid {PK, FK} mark 1.1 forename achieves ► surname gender where PK and FK refer to primary key and foreign key, respectively.
