How CICS program validates the data in the database using COBOL logic?

- Create a map in CICS to map the user id with password.

- Ensure the following code is placed in the program:
MOVE USER TO WS-USER.
MOVE PWD TO WS-PWD.

- Use the SQL queries as follows:
SELECT USERNAME FROM EMPLOYEE WHERE USERID LIKE ‘%S’

- Validate by matching the values and move the same values of USER and PWD, if matches.

- Otherwise move different values of USER and PWD.
