Object Oriented System Analysis & Design

OBJECT ORIENTED
SYSTEM ANALYSIS &
DESIGN

INTRODUCTION
Object-oriented define as the system in which all data is presented as a discrete objects,
through which the users and other aspects can interact. This system will enable the user to
mainly concentrate on the tasks instead of the tools. OOAD object oriented analysis and design
can be understood as a technical process for designing the system with the use of the object
oriented programming language (Flores, Torres and Fonseca-Delgado, 2019). Object oriented
system analysis (OSA) is the systematic approach for the system that are developed on the basis
of existing methodologies' strength, also accounts the weaknesses. As the base for the OSA
models are the object class. OSA is the approach for designing the software, which used to plan
the system that are able to interact the object to solve any issues related to the software. In this
system it also uses the visual modelling thoroughly during the software development process in
order to guide the stakeholder interaction.
This report lay out the areas which involve the package diagram for the online student
registration, also describe about the factors which are required to include for design strategy. It
further describes about the computing client server, key principle of the UI design, UI process
steps, navigation control in the UI and output design principles.
MAIN BODY
1. Package diagram
Package diagrams are the structural based diagram which is used by the organization in
order to show their systematic arrangements of the different elements in the package form. This
diagram form is generally represented the layered architectures of the visual organization while
using the UML classifier. These diagrams are mainly aims to organize the element of the
massive system in a structural form, it involves the key deliverables, other diagrams. Its main
purpose is to simplify the complexity of the class diagrams (Mekruksavanich, 2017).
Concept of the package diagram:
This diagram follows the hierarchical approach which involves the nested packages. For
the nested package their modules are class based diagram. Certain rules are involves in this
diagram which are that name for two packages should not be identical, but for the classes it is
allowed to have same name in different packages.

2. Factors that are considered in order to select the designing strategy
Following are the factors which are consider in order to selecting the designing strategy-
Select the interface elements:
As users are very familiar with the interfaces elements, therefore it is important to keep the
layout consistent, it will help in task completion. Interface elements involves the input controls
which are buttons, radio buttons, toggles. Also involves the navigational and containers
