CHAPTER ONE
INTRODUCTION
A
system, with numerous definitions can be literally seen in a computer way as a
collection of the hardware and software components of a computer.
According
to Stella C. Chiemeke and Franca A. Egbokdara (2006), a system is set of
components that interact to achieve a common goal. In another sense, a system
is a group of interrelated or intersecting elements forming a unified whole.
In
this modern age, computers have verified the cause of their existence. The
advent of computers in our society caused a lot of criticism on the danger it
poses on the society. Critics of computer and new techniques express their fear
on how computers will displace and replace all human skills thus resulting to
mass unemployment but the presence of computer on virtually every field of
today’s fast life has proved the critic wrong as the invention of computers and
new technologies continues to create additional jobs for those who identify
themselves with computers and new technologies. This make computes partner to
human beings in any fields of human endeavor.
“Decisions are largely based on principles and
experience. In recent times, efforts are being made to build intelligence into
computer system, whereby the computer can be used to process large volume of
structured and unstructured information for decision making.” Said Uzoka in
Hampo, J.A. (2011).
This system, DIGITAL DIARY is a window based
system. It is an electronic and computerized means of periodic record keeping,
scheduling, and reminder and so on. More than one person can use this personal
digital diary, with full privacy and data security. This is in contrast with
the manual personal diary that only one person uses it and it is without
privacy and data security. Access to this system is simply by password and
username.
1.1
BACKGROUND OF THE STUDY
In this modern age, computers
have verified the cause of their existence. From sleeping and eating to
exercise and travelling, technologies now allow us to track and analyze every
detail of our lives. Due to the presence of advance computing technology and
developed minds in the technological of life, almost everything has been
digitalized or automated. Notably, the social life of many today has been automated
via social network like facebook, twitter and talkdeygo.
“A diary is a record (originally
in the handwritten format) with discrete entries arranged by date, reporting
what has happed over the course of a day or a given period”, says Wikipedia,
the free encyclopedia. From the aforesaid, a diary is a periodic or a daily
with discrete entries. Diary is of diverse form/type ranging from personal
diary (a diary which may include a person’s experience and/or thoughts or
feeling, including daily comment on current events outside the writer’s direct
experience) to travel diary, diet diary, dream diary and so on. A diarist is
someone with the responsibility of safe keeping a diary. Or simply “someone who
keeps a diary”, according to Wikipedia. Samuel Pepy (1633-1703) is the earliest
diarist that is well-know today and his diary preserved in Magdalene College,
Cambridge were first transcribed and published in 1825.
Diary played a major role in many
aspect of human civilization as they are means of record and when review
generates a feedback(s) for advance and immediate implementation, notably
institutional diaries, government records and business ledgers likewise
military records. Diaries have also helped by providing information for a
memory, autobiography or biography. According to wikipedia, “by extension, the
term diary is also used to mean a printed publication of a written diary; and
may also refer to other terms of journal including electronic formats example
blogs, forum and internet diary”
According toMerriam-webster in
Wikipedia, “The word diary comes from the Latin word ‘diarium’ which means
‘daily allowances’ from ‘dies’ which means ‘day’, likewise journal from the
same root word ‘diurnus’ meaning ‘of the day’.” The work of Marcus Aurelus, a
Roman emperior titled ‘To Myself’, written in Greek in the second half of yhe 2nd
century AD displays many character of a diary, but the oldest extant diary came
from the Middle East and Asian culture. In the 9th century AD, a
Chinese scholar Li Ao kept a diary of his journey through Southern China.
Digitalizing diary has changed
the meaning of the term ‘diary’ all together. The advent of computers in our
society caused a lot of criticism on the danger it poses on the society. Digital
diaries have today had more functions than just storing of data as against the
conception of most individuals. The continuous availability of internet
services and electronic/technological gadgets has made many people adopt it as
a medium to chronicle their lives with the added dimension of an audience.
Below are examples/forms of
diaries;
·
Personal
diary – which may include a person’s experiences and/or thoughts or feelings,
including other current comments.
·
Sleep
diary – a tool used in the diagnosis and treatment of sleep disorder. It is
also called sleep log.
·
Travel
diary/diary – is the documentation of a journey or series of journey. At times
it is called road journal/diary
·
War

OBJECTIVES OF THE STUDY
The objective of this research is
as follows:
1. To design an automated diary (a
digital diary) that is window based system using vb.net as its front end design
and SQL server as its back end design. This diary will:
a) Eradicate and/or limit paper work
b) Provide privacy, since your
digital diary can only be stolen by the ignorance of the diarist through
password and username publicity
c) Maintain and promote history as
digital diaries cannot get lost, old or
decay
2. To explain digital diary, its
forms and importance to human
3. To itemize the advantages of
digital diary over hand written diary
4. To show the new features of
digital diary that made the term ‘diary’ to revolutionize
1.3
SCOPE OF THE STUDY
There are diverse forms of
digital diary with various features like audio, video, graphics, text and
encryption/decryption but this research is streamlined to a personal digital
diary with features like text, graphics and/or audio/video.
1.4
MOTIVATION OF THE STUDY
The ease of privacy
intrusion caused handwritten diary and the frequent lost/theft of manual for
the purpose of blacking mailing the diary owner or diarist is a serious threat
to individuals and organization.
The advance and
tremendous features coupled with data/information security has prompted or
motivated this research.
1.5
STATEMENT OF PROBLEM
Diaries often contain both good
and bad content. The ease at which
Data/information is leaked out
from a manual diary resulting to blackmailing of person(s) with the
bad/negative content(s) in the diary. This is a big and mind disturbing issue
as an individual’s good reputation can be dented with a negative content from
his/her diary, denying him/her the good of tomorrow. Hence privacy and
confidentiality has become a problem to handwritten or manual diaries. Thanks
to technology, as the negative issues of manual diary has been addressed by
digital diary.
1.6
LIMITATION OF THE STUDY
This research is
limited by the availability of time to access resource/materials, the materials
reviewed as well as the scope of the study. Though, the available resources and
materials are optimized.
The proposed system
is designed on .NET frame work. Restricted access to some vital and important
data and information is also a limitation to this study.
1.7
METHODOLOGY
Relevant literature and
authorities were reviewed and a critical study of digital diaries and their features
was done.
Software methodology is the set
of rules and practices used to create computer software. It is composed of any
one of the software development models used together with at least a techniques
thus,
METHODOLOGY = SOFTWARE MODEL +
TECHNIQUES(S)
An in-depth literature review is
done using document review and the internet.
The proposed design will be
implemented using MS Visual Studio 2008 tools and Visual Basic (VB.net) as the
programming language and MS SQL server 2005 for the database.
The methodology to be adopted for
this project is the SSADM (Structured System Analysis and Design Methodology).
The SSADM emphasizes on the completing a phase of the software development
before proceeding to the next phase and also being able to go back to the other
phases in a purely sequential manner. The model used for this project is the
RAD (Rapid Application Development model proposed by IBM (International
Business Machine) in 1980 and introduced to software community by James Martins
through his book Rapid Application Development).

and RAD takes a modular approach to this student’s verification system using a
best practice guide to ensure the successful implementation of the parts of
this project sequentially. The design and testing of the system’s relational
database management system (RDBMS) is to confirm the design specification. Therefore
the window based graphical user face (GUI) will be integrated to input data
into the system’s database. This project starts small and break down the
implementation process into modules that are attainable based on the adopted
requirement and analysis methodology.______________________
