which is more accurate? and are they even right?

Instructions:

Write the suitable SQL statement to answer the following questions based on the following tables ( image for better table)

Table Name: Employee
 EMP_ID             FNAME               LNAME               SALARY         JOIN_DATE              DEP_NO                     
101                  John                  Abraham            10000                   01-JAN-13          11             
202                  Michael                 Clarke                80000                  01-JAN-13          22            
303                       Roy                   Thomas              70000                  01-FEB-13          11             
404                     Tom                       Jose                  60000                   01-FEB-13          22             
505                        Jerry                    Pinto                 65000                   01-FEB-13               22             
606                    Philip                  Mathew              75000                  01-JAN-13          33                 
707                             Thomas              Jack           65000                  01-JAN-13          33

Table Name: Reward
 EMP_ID             REWARD_DATE               AMOUNT
    101                       01-FEB-13                       5000
     202                     01-FEB-13                        3000
303                          01-FEB-13                        4000
101                          01-JAN-13                        4500
202                          01-JAN-13                        3500

Table Name: Department
DEP_NO             DEP_NAME
 11                        Banking
22                         Insurance
33                         Services
44                        Marketing

the question is:
Write the DDL statement for defining the Employee table. 

(Assume that the Reward and Department tables have already been created)

my solution is this ( 

CREATE TABLE Employee (

EMP_ID CHAR(3) NOT NULL,
FNAME VARCHAR(15) NOT NULL,
LNAME VARCHAR(15) NOT NULL,
SALARY DECIMAL(10,2),
JOIN_DATE DATE
DEP_NO CHAR(2) NOT NULL
PRIMARY KEY(EMP_ID),
FOREIGN KEY(EMP_ID) REFRENCE Rewrad,
FOREIGN KEY(DEP_NO) REFRENCE Department
                                                                        );
)
my other solution is (

CREATE TABLE Employee (

EMP_ID INTEGER PRIMARY KEY,
FNAME VARCHAR2(15),
LNAME VARCHAR2(15),
SALARY INTEGER,
JOIN_DATE DATE,
DEP_NO INTEGER
                                                                        );
)

which is more accurate? and are they even right?
