Assignment Brief and Guidance:
Assignment scenario
Scenario : You have applied for a post as a trainee with a software development company and have been
invited for an interview. You have been passed the presentation to demonstrate your problem solving and
basic programming skills. Now you are given a more challenge task to create a fully working, secure
application that has been developed using an IDE and adheres to coding standards for a detailed business
problem.
Tasks
You will discuss a suitable problem with your mentor and list the user requirements before designing,
implementing (coding) and testing a solution. You will create a report that should include:
● Introduction to your program (list of requirements and screenshots of program)
● Explain some of programming paradigms. Evaluate why and how your program use these (or some of)
paradigms.
● Explain the common features of an IDE should have and evidence of how the IDE was used to manage
the development of your code.
● An evaluation of developing applications using an IDE versus developing an application without using an
IDE.
● An explanation and evaluation of the debugging process in the IDE used and how it helped with
development.
● An explanation and evaluation of coding standards used in your program and the benefits to
organisations of using them.
The working application produced must also be demonstrated together with the presentation.
Case Studies
You can choose one of following case studies to implement
Hotel Management System:
A Hotel Management System is a software built to handle all online hotel activities easily and safely. This
System will give the hotel management power and flexibility to manage the entire system from a single

scheduled flight (all stakeholders will be notified).
Restaurant Management System
A Restaurant Management System is a software built to handle all restaurant activities in an easy and safe
manner. This System will give the Restaurant management power and flexibility to manage the entire

ASSIGNMENT 2 ANSWERS
P2. Give explanations of what procedural, object-oriented and event-driven paradigms are; their
characteristics and the relationship between them.
1. Procedural paradigm:
1.1 Definition:
A new developer's initial programming paradigm may be procedural programming.
Procedural programming is derived from structured programming, based upon the concept of the
procedure call.
Procedural programming is a list of instructions to tell a computer how to run from the code.
Procedures are also known as routines, subroutines, or functions, simply contain a series of
computational steps to be carried out.
Simply put, Procedural Programming involves writing down a list of instructions to tell the
computer what it should do step-by-step to finish the task at hand.
P a g e | 3
2. Object – oriented paradigm:
2.1 Definition:
Object-oriented programming (OOP) is a computer programming model that organizes software
design around data, or objects, rather than functions and logic.
An object is a data field with its own set of characteristics and behavior.
OOP focuses on the objects that developers want to manipulate rather than the logic required to
manipulate them. This approach to programming is well-suited for programs that are large,
complex, and actively updated or maintained.
An object-oriented program's structure also makes it useful for collaborative development, where
projects are divided into groups. Code reusability, scalability, and efficiency are also advantages of
OOP.
The first step in OOP is to collect all of the objects a programmer wants to manipulate and identify
how they relate to each other -- an exercise known as data modeling.
2.2 Characteristics of Object – oriented paradigm:
P a g e | 4
2.2.1 Class and Object:
Class : A group of objects that share common properties for the data part and some program part
are collectively called class. With the help of a class, an object's entire set of data and code can be
turned into a user-defined data type. Objects are type class variables. We can create any number
of objects that belong to
a class once it is defined.
Objects : In an object-
oriented system, objects
are the basic run-time
entities. They could be a
person, a place, a bank
account, a table of data,
or anything else the program needs to deal with. The object-oriented approach is based on the
idea of combining data and function into a single unit, which is referred to as an object. The term
objects means a combination of data and program that represent some real word entity.
Ex : Class and Object : C# programming language
Create an object called "myObj" and use it to print the value of color:

2.2.3 Encapsulation:
Encapsulation is a process in which data members and member functions are bound together in a
single unit in C#. Because it will combine various types of data members and member functions
into a single unit, the class is the real-time example of encapsulation in c#.
Generally, in c# the encapsulation is used to prevent alteration of code (data) accidentally from
the outside functions. In c#, by defining the class fields with properties, we can protect the data
from accidental corruption.
If we define class fields with properties, then the encapsulated class won’t allow us to access the
fields directly. Instead, we need to use getter and setter functions to read or write data based on
our requirements.
Advantages of Encapsulation:
Data Hiding : The user will have no idea about the inner implementation of the class. It will not be
visible to the user that how the class is stored values in the variables. He only knows that we are
passing the values to accessors and variables are getting initialized to that value.
Increased Flexibility : We can make the variables of the class as read-only or write-only depending
on our requirement. If we wish to make the variables as read-only then we have to only use Get

2.2.4 Abstraction:
In c#, Abstraction is a principle of object-oriented programming language (OOP), and it is used to
hide the implementation details and display only essential features of the object. In Abstraction,
by using access modifiers, we can hide the required details of the object and expose only
necessary methods and properties through an object's reference.
In object-oriented programming, a class is the perfect example of abstraction. In c#, we can create
a class with required methods, properties and we can expose only necessary methods and
properties using access modifiers based on our requirements.
Data abstraction is the process of hiding certain details and showing only essential information to
the user.
P a g e | 10
Abstraction can be achieved with either abstract classes or interfaces.
The abstract keyword is used for classes and methods: Abstract class : is a restricted class that
cannot be used to create objects (to access it, it must be inherited from another class). Abstract
method : can only be used in an abstract class, and it does not have a body. The body is provided
by the derived class (inherited from).
Advantages of Abstraction:
Abstraction makes code readable and simpler to understand. The codes are simple to understand
as the complexity of the code is hidden from the user.
The size of the code is reduced as through abstraction we do not show unnecessary codes.
If we don’t apply abstraction to codes then it is difficult to maintain the codes.
Through abstraction, we simplify the representation of the Domain Model.
Abstraction grouped the data of the same type together and separate different types.
