1. Student database

Consider the following relations:

P.K. STUDENT (snum: integer, sname: string, major: string, level: string,age: integer)

F.K.

CLASS (name: string, meets at: string, room: string, d: integer)

P.K.

ENROLLED (snum: integer, cname: string)

P.K.

FACULTY (fid: integer, fname: string, deptid: integer)

The meaning of these relations is straightforward; for example,Enrolled has one record per

student-class pair such that the student is enrolled in the class. Level is a two character code with

4 different values (example: Junior: JR etc)

SQL> create table student(snum number,sname varchar2(30),major varchar2(20),levl

varchar2(2), age number, constraint st_pk_1 primary key(snum));

Table created.

SQL> create table faculty(fid number,fname varchar2(30),deptid number, constraint

fc_pk_1 primary key(fid));

SQL> create table class(name varchar2(10),meets_at varchar2(10),room varchar2(10),fid

Table created.

SQL> create table enrolled(snum number, cname varchar2(10),

2. Flights Database

The following relations keep track of airline flight information: P.K. FLIGHTS (no: integer, from: string, to: string, distance: integer,Departs: time, arrives:

time, price: real)

P.K. AIRCRAFT (aid: integer, aname: string, cruisingrange: integer)

F.K. P.K. F.K. CERTIFIED (eid: integer, aid: integer)

P.K. EMPLOYEES (eid: integer, ename: string, salary: integer)

Note that the Employees relation describes pilots and other kinds of employees as well; Every

pilot is certified for some aircraft,and only pilots are certified to fly.
