How might we specify the following SQL in MongoDB $?$

CREATE TABLE course $($

code CHAR$(3)$ PRIMARY KEY,

name VARCHAR$(30)$ NOT NULL,

credits TINYINT NOT NULL

$)$;

INSERT INTO course $(`$code$`,`$name$`,`$credits$`)$

VALUES

$(\text{'}$WSD$\text{'},$ 'Web Systems Development', $75),$

$(\text{'}$DDM$\text{'},$ 'Database Design & Management', $100),$

$(\text{'}$NSF$\text{'},$ 'Network Security & Forensics', $75)$;

CREATE TABLE Module $($

code CHAR$(2)$ PRIMARY KEY,

name VARCHAR$(30)$ NOT NULL,

cost DECIMAL$(8,2)$ NOT NULL,

credits TINYINT NOT NULL,

course$\_$code CHAR$(3)$ NOT NULL,

CONSTRAINT fk$\_$course$\_$code

FOREIGN KEY $($course$\_$code$)$

REFERENCES course $($code$)$

ON UPDATE CASCADE

ON DELETE RESTRICT

$)$;

INSERT INTO module $(`$code$`,`$name$`,`$cost$`,`$credits$`,`$course$\_$code$`)$
