Suppose I want to create 2 tables -- Department, Student

Student {
name,
id,
address
}

Department {
Dept_name,
Students[] student,
}

in which "department" table contains a group of "student".

How to do the "create table" statement for "department" ? Please help.

In your case it is prefarable to create the tables like :

Create table Dept(
Dept_id number,
Dept_name varchar2(20),
CONSTRAINT DEPT_DEPTID_PK PRIMARY KEY (DEPT_ID));

Create table Student(
stud_Id number,
Stud_Name Varchar2(50),
...
Dept_id Number,
CONSTRAINT STUDENT_STUDID_PK PRIMARY KEY (STUD_ID),
CONSTRAINT STUDENT_DEPTID_FK FOREIGN KEY (DEPT_ID)REFERENCES Dept(Dept_id)
);
 
I agree. Here's the link: http://aspose.com/file-tools
