Consider the following database instance.
For each of the following questions, show the contents of the database (1,e, re-draw the
tables showing the data) after performing the given SQL statements. Assume each SQL
statement is performed on the original database instance considering the effect of the
previous statements, so these are done in the order listed. After each step the data is
committed (written) to the database.

ID should be primary key
Insert at least 10 records in the Entity Employee with respect to their type.
a) Implementation the example of stored procedure now creates the stored procedure which:
a. Have an ability to insert the record in the table.
b. Have an ability to delete the record in table.

The following are the basic processes of Boarding School Outing System.
Student may enter the outing request such as date, reason, check-out time
(check-in time is auto-set at 6.00 PM) to request for outing. The outing request
details are stored in 'Outing Request' record.
Warden can view the outing request and he/she may approve or disapprove the
request. The status of the request is updated in the Outing Request' record.
Once the status is updated, a short message service (SMS) notification will be
sent by the system to the student and parents. The hand-phone numbers are
retrieved from the Student' record.
Student will check-out and check-in via this system whenever he/she is about
to leave from the school and reports back to the school. The data (date and time)
is kept in the existing outing record.
Note:
**Definition of outing (in boarding school context): A day out from the hostel/school,
normally during the weekend.
Based on the scenario above:
