particular date they want to know. The activities of member will be available to the guardians to
view. The interaction between the park rangers and members can be easily documented and
viewed. The details of the members can also be update by the guardians in the system and they
can give feedback for the park services. The online training courses are also there in the present
system for the guardians. The present system will allow ideas and feedback from the guardians.
This will result in assistance for the development of the system and also help in expansion of the
organization. The guardians can also provide information regarding the privacy and user
interface of the present system.

used to evaluate the member’s responses. The time will be allocated for the guardian to remain in
the VCI Park. The guardian will be able to set different criteria of activities for each day. The
system will be able to provide information regarding the maximum time, a member can spent in
