Transcribed Image Text: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

1..1
1.* aid {PK}
cid {PK}

cid {FK}

sid {PK}

aid {PK, FK}

where PK and FK refer to primary key and foreign key, respectively.

(HInt: It is easiest to use LIKE in this instance.) In addition, you are requested to replace either 'Man-Made' or 'Man Made' with the word 'Synthetic'. Only include ProductIDs between 1050 and 1060. Show the following in your answer: ProductID, ProductName, Composition, and the modified composition field as 'NewComposition'.
