CURRENT SYSTEM ANALYSIS AND MODELLING
Executive Summary
The Virtual child International Information system for the development of an information system
for the management of the data of the customers who have enrolled into the information system.
There are different various activities that are provided as a service to the children’s and their
records are maintained in the information system for providing efficient service to thee
customers registered with the park. A database of the information system is created containing a
set of questions that the children’s need to answer during entering the park. A checking is done at
the entry point for the validation of the entry of the children and the time is assigned to the
member depending on the number of right question answered by the children. For the
development of the information system some criteria is assumed and a list of functional and non-
functional requirement is created.

Task Part A: The Report Components
Introduction
The report is prepared for the Virtual child International Information system (VCI)
because it needs an information system. For the analysis of the requirement of the project the
background of the organization is analyzed and compared with the scope of the project for
starting the development of the information system. The scope of the project consists of the list
of functional and the non-functional requirement which is important for the feasibility study of
the project. The documentation of the report helps in evaluation of the system requirement and
reduce the errors in the information system. The flow of the data in the information system is
defined with the creation of the data flow diagram. For the identification of the relationship
between the entities the entity relationship diagram is created and attached with the report.
Company /Organization background
The Virtual Child International organization is a company that operates a park for the
children, where the children can come to the park after their school and perform some
recreational activities that would enhance their education as well. The park allows the guardians
to accompany the children inside the park. The main users of the system are guardians of the
students who enroll them for the activities within the park. In addition to this, the park consists of
staffs who assists the guardians in guiding through the park. The staffs are known as the Park
Rangers. The park rangers. In addition to this, the organization maintains a system where the
members have perform certain tasks before they are allowed entrance to the park. At the entrance
the children are allowed entry into the park and the guardians are required to pay the fees for the
children. The children allowed entry only after the payment have been done by the guardians.
