SYSTEMS ANALYSIS AND DESIGN2
Introduction:
System analysis is the process of collecting problems and fact about the current system
and analyzing the issues to find gaps. Moreover, system analysis provide the basic building
blocks for creating a solution for current issues. System design refers to the process of modelling
the requirements of proposed solution identified during system analysis process. System analysis
and design provide the opportunity to understand input and output of business requirements. In
addition, it provides the way of recognizing the gaps and potential solution to these gaps. UML
models are great source of identifying static and dynamic nature of the proposed application.
Data models like DFD and ERD provides insights to data elements required for running the
business.
This report is written based on current system and future system of ABC Car Fleets. It
requires a new system to control and track its business process. The report includes the system
requirements, fact finding techniques and system development approaches. In addition to that,
report will also focus on visualizing the nature of the system and data requirements through
various models.
System Requirements:
For developing a system, two types of requirements are needed to be identified. These
two requirements are functional and non-functional requirements. Functional requirements
shares the idea of what system will be executing to meet business and user requirements. Non-
functional requirements concentrate on describing the quality of service that system will provide
to users.

SYSTEMS ANALYSIS AND DESIGN3
Functional Requirements: In the following section potential FR or ABC Car Fleet
system is provided.
i. Authentication: Authentication refers to the security policy that prevent any
unwanted user from accessing the privileged system functions. The users will
have login credentials such as user id and password to login to system. Those
users who do not have these credentials will not get access to core functions.
ii. Authorization: Authorization, on the other hand, is another security policy that
prevents any user from accessing information or function that is not intended for
him/her. Authorization has layers that are mainly based on the user types.
Authorization makes sure that customers and managers have two different set of
tasks to complete. Customers cannot see the sales, employee or other customer’s
data, whereas manager can.
iii. Registration: The registration process sets the authentication credentials and
authorization level for a user. In order to register, the customers have to provide
all the required information like customerName, Address, Telephone, mobile, e-
mail, username and password. One thing to remember that username accepts only
unique values. Therefore, username cannot be same for two individual customers.
iv. Data Storing: It is an essential or can be said most important part of the business.
User specific data is what makes a system dynamic. The system will collect data
from customers through various forms, clicks and other interaction methods.
These data will be processed, verified and stored in a central database for later
use.
