INTRODUCTION
System analysis and design are defined as an approach which used by the businesses to
identify the business situation to make improvement by applying different procedures. This
process mainly aims to shape the business to improve the functionalities of the organization so
that it will become easier to achieve the goals and objectives (Sintoris & Vergidis, (2017)).
System analysis is the effective process of finding and gathering the facts to identify the issues
so that relevant actions can be taken to resolve the issues for smooth running of the system. Its
purpose is to studying the parts and components of the system to find its objectives, it is issue
resolve techniques which enhance the efficiency of the system. System design is required when
there is a new planning of the business, as to replace the existing system by identifying its
components are useful to fulfil the specific requirement. This report will cover the scenario
which shows that the certain requirement for the Book issue process or to make registration on
the system. Report will illustrate the functional and non-functional requirement in which it
involves the description of the actor and non actor and their involvement in the system. It also
includes the Use case diagram and its description.
MAIN BODY
Question 1
Functional and non-functional requirement:
Functional requirement is defined as a component of the system where it work as to act
between the input and output. It is the process which involves the information about the system
which must offered by the software. It can be a data, business process any process which is
required by the system to perform certain functions (Qu and et.al (2019)). Non functional
requirement involves the explanation about the system elements as security, system reliability,
functionality etc. its main aim is to ensure that the running system is effective or reliable. In this

case scenario functional requirement are the common way which involve the interaction with the
user and their requirement for the system. This functional requirement will guide the
management team in the right direction. Non functionality in which employees are not allowed
to update their information regarding salary.
Role of actor and non actor into the system
The actor identified in the system is the users which are interacting with the system in
this case scenario each actor plays a specific role which are as follows.
Admin: The main duties of the admin involves the preparation, organizing, collecting the
information for the successful running of the business. They manage the supplies of the and
prepare the financial report to decide the budget (Cimini, Pinto & Cavalieri, (2017)). In this case
admin registered to the system and watch all the activities if problem occur they provide the
proper solution to overcome the issue.
Management: Management here define as the management team which ensures all the activities
are implementing effectively. They are the employees who provide the services to the customer
they login into the system and analyse all the workplace activity.
User or reader:Reader are those customers who interact with the system to access the services in
this reader made request to admin page if there request accepted then they proceed to issue the
book or once they have issued the book they can also allow the different user to made book
acquisition request for that they need to provide the detail of the book (Mohammadi, (2017)).
Author: Author in the book is identified as a actor who have the role to made the request so it
will be reflected on admin page as they can provide the detail of their book along with the bank
details so it will provide other book options to the readers.
Non human actors are defined as a system, its components and servers. In this case the
login system, attributes of the system are the non actor which identify as user made the request
then it will lead to the server and appears on the admin system then they provide the access by
sending approval request.
Question 2
Use case diagram:
Use case diagram in the Unified modelling language is defined as a complete detail of the
system in summarize pattern. It describes the interaction between the actors and the system, it
involves the use of symbols and components which are required to create a use case diagram. It
