ABSTRACT
Reason for a telephone directory in
to have a guide or what we can call a director. Subscribers of the
telecommunication industry of may not find it very easy to locate information
on a voluminous pages of a telephone directory, take an instance where we have
over 70,000 subscribers, it will take a whole lot of time before one can easily
trace his/her information (A Directory contains information like Name, Address
and avacodes of subscribers) because of this time wasting and inflexible way
this time wasting and unflexible way this manual approach act, computerization
become a meant do activities that must be carried out on directory system.

INTRODUCTION
One of the most exciting aspects of
the information technology revolution is the combining, telecommunications with
computing. This allows information to be processed by computer and then
transferred down telephone lines to the recipient computers. The speed at which
this can be done surpasses more conventional communication techniques. The
process is no longer limited to telephone.
The combination of computer and
telecommunication technologies has heed profound effect on the way computer
system are organized.
NITEL (Nigeria Telecommunication
Plc) is one of the organization that gives communication services to subscriber
(Although there are presently other private driven communication services
subscribers.
NITEL has the list of all its
subscriber in a book where they keep records of each subscriber in a unique
way. Periodically when new subscriber come in, they update the book let it
become a routine when a subscriber comes in or leaves to update the booklet.
This way of producing information or
producing of this booklet will always be hindered since manual operation is
involved and most time, it be can become error prone and then misleading
people.
This booklet is known as TELEPHONE
DIRECTORY which is the fulcrum or pivot of this project. Since computer
revolution involves and covers all works of life just as we have said earlier,
when adopted and it replaces the manual method of processing, there is indeed
going to be a complete revolution in the system.
Using of key fields for searching
and retrieving of any viable information of any subscriber will be easer and
fast.
STATEMENT OF THE PROBLEM
Many people lacks the will to read
books either of small or large size. Unfortunately, the telephone Directory in
a voluminous and it become tasky to search through such text and moreso it
involves lot of time.
Inflexibility of this manual system
is nothing to write home about hence computerization of the system becomes
imperative and nothing to ignore because it is not easy to modify or update
information.
Finally, another problem facing this
system is the cost of production. It is always involve much money to produce
booklet of telephone Directory. The maintenance also involve using the
money and they all are carried out periodically.
PURPOSE OF THE STUDY
Having states the problem of this
work (The system in review) than what my reason or reasons of going into the
study?
The system is defectize and does not
belong to a Millienia generation like ours where computer have taking he entire
of the stage and the world is now in what is called “Jet age” (Word or phrase
associated with speed).
To uplift the standard of
telecommunication in Enugu East Local Government Area, Computerization of their
system becomes a must. Another thing is flexibility, as stated in the problem
that the manual system is not flexible, avoiding time wasting in such system
communication automation must come in.
AIMS AND OBJECTIVES
One of the aims of his work is to
produce a computer based system, that will be able to carry out the operations
of the present system effectively and reliably. Another thing is to produce an
less expensive system that is easy to maintain and update. Finally, good work
is commendable, so when this work is successfully completed I believe the
society and people around will appreciate my work.
SCOPE OF STUDY
This study is concerned with the
Telephone Directory Operations alone the searching, updating and editing are
only to be carried out and nothing beyond this in the work, but there is always
room for improvements so whoever wish to start from hence, it is a good idea to
be welcomed. This method helps and encourages improvement.
LIMITATION OF THE STUDY
Factors abound to be faced during
this work and they are inevitable. Such factors will actually be constraints to
the high attainments of getting the greatest percentage of this project such
factors include examination which is around the coroner, cost of transportation
to and fro my case study environment, lectures and quizzes, assignments and
many other uncertainties.

HOW TO IDENTIFY SCAM/FRAUD
As a result of fraud in Nigeria,
people don’t believe there are good online businesses in Nigeria.
But on this site, we have provided
“table of content and chapter one” of all our project topics and materials in
order to convince you that we have the complete materials.
Secondly, we have provided our Bank
Account on this site. Our Bank Account contains all information about the owner
of this website. For your own security, all payment should be made in the bank.
No Fraudulent company uses Bank
Account as a means of payment, because Bank Account contains the overall
information of the owner
