ISYS225 Systems Analysis and Design: Semester 2 Activities Report

This document presents a comprehensive report on fundamental concepts in Systems Analysis and Design, covering activities from week 5 to week 11 of the ISYS225 course. It includes various activities such as listing basic and supporting activities for a lemonade stall, creating context-level and level 0 Data Flow Diagrams (DFDs), and addressing questions related to HIPAA compliance in real-time glucose monitoring systems. The report also delves into object-oriented systems design, identifying objects for a car buying system and a university library system, and constructing class and communication diagrams. Furthermore, it includes activities related to class diagrams for books and related product content, and outlines deployment activities for a parcel courier service company's system. The document demonstrates a thorough understanding of systems analysis and design principles through practical examples and diagrams.

Activity 6
Question 1
Yes.
The Health insurance portability and accountability (HIPPA) is applicable to the real time
glucose monitoring (RTGM) as the RTGM transmits the electronic information regarding the
status of the patients glucose levels between the patients mobile devices and the server’s
processing components and therefore the system need to be secure in order to prevent malicious
activities from the un authorized users who may have illegal access to transmitted health
information.

6Fundamental Concept in Systems Analysis and Design
Question 2
There will be data security during its transmission between the mobile devices and the server
components which will be enforced through the application of the encryption technique which
mainly encodes the information and data transmitted by hiding it from the un authorized system
and information users and thus enforcing data safety during transmission between mobile and
server components.
Question 3
The data of lost or stolen devices can be protected through setting of strong passwords and
usernames however the devices should be configured for daily back system and also to be fixed
with a track device to locate the lost or stolen device possible location.
Question 4
The health officers can access the health information from the system server using the
workstations or the mobile devices, then the health system will be recording and examining the
system access into the ePHI where the devices details and access time is recorded and if any un
recognized system is detected the operation will be terminated immediately. In case the users use
external devices they require installing them with antivirus applications to protect the malwares
and the malicious attacks (Award, 2013).
Question 5
There will be requirement of ePHI security for the signal transmission on wired or wireless
media between the work-stations devices and the server components in order to ensure that the
signals are protected through the encryption to enforce data confidentiality and limiting changes
to the servers that are managed by the third parties (Laplante, 2013).
Activity 7
a. How object-oriented systems design can be applied
The object oriented system design is applied in this system since the car buying system
development will use object oriented programming which will involve number of entities and
their respective attributes that links the various objects.

b. List of all the objects
i. Car
ii. Customer
iii. Seller
iv. Manufacturer.
c. Two objects class diagram
Activity 8
List of the possible objects
The following are the university library system objects in the “library return books”.
i. Book.
ii. Book_on_loan.

Activity 10
Parcel courier service company system deployment activities
a) Training users
In order to deploy the system or account sub-system module as the first module in the
organization the development team will train the system users and the target users will be the
account team and the management members. Among the things that the team will be trained in
are the following:
i. How to securely open the computers system.
ii. How to securely start the installed sub-system.
iii. How to sign in the sub-system.
iv. How to operate the system like preparing trial balance, balance sheet among others.
The management team will be trained on the following aspects:
i. How to securely open the computers system.
ii. How to securely start the installed sub-system.
iii. How to sign in the sub-system.
iv. How to operate the system like checking the profits and amount received reports.
Therefore each system user will be having unique privileges on system access.
b) Deployment order
When the staffs and system users are fully trained by the system developers, the system modules
will be installed and configured into the computers systems where the newly installed system
will be executed parallel to the old system for a period of six weeks for the staffs to be used to
the new operations then the organization data and operations will be shifted to the new installed
system after six weeks elapses.
c) Support activities
The system will be installed in the organization and the system users will be using it and incase
of any error arising the system users will be alerting the technical team to fix the system errors
and bugs and ensure it is operating and running normally (Goyal, 2011).
