Tables in Oracle, and other databases are created with the create table statement, where you define the columns of the table by specifying their names and data types.

create table employee (
	emp_id		number,
	first_name	varchar(30),
	last_name	varchar(50),
	start_day	date,
	salary		decimal(8,2)
);

create table airport ( 	
	city 			text, 
	airport_code 	char(3), 
	x_coordinate 	number,
	y_coordinate 	number,
	z_coordinate 	number
);
