CHAPTER ONE

• INTRODUCTION

Computer has proved its uniqueness in different works of life. It provides and in different ways reduces complexity and generate.   Maximum output.   This made possible through the unique features of computer system in the areas of speed, information storage and retrieval automatic is the important faced of economy in the society. If provides adequate communication causes great place havoc in the society.   The nature of communication determines the mode of transmission.

Communication through the telephone system is one of the fastest and most reliable modes of message transmission.   Through the telephone system, information can be cone eyed quickly and adequately.   Information gets to the destination immediately and the sender receives feedback at the same time.   Information storage and retrieval is also achieved through the telephone system.   Information can be stored in the absence of the receiver.   The receiver can also retrieve this information at any time.   Acquiring the phone for use is by subscription. Individual or groups that wish to acquire phone always subscribe through the organization in charge.   Information about every subscriber is taken and stored for reference purpose.   Phone subscriber pay bills according to the calls made.

The outmost speed at which the universe is being turned into a global world is attributed to the sophistication in the telecommunication industry. These radical changes have been made possible by the intention of digital technology in electronics and telecommunication analogue.   This means that the signals being handled, processed or transmitted are presented by voltage whose amplitude quinsy vary continuously with time.

Consequently, in the telephone system the transmitted signals an direct representation of the speech waveforms.   This did not provide the easy and continuous flow of soured wave in the system.   This project is aimed at developing a system that will help in the billing section of NITEL (Nigeria Telecommunication Benin) to enable serve it customers effectively. Bill them accurately and also give customers details of how they are being billed.

1.1     STATEMENT OF THE PROBLEM

The quest for more sophisticates and affective system that can handle the telephone bills of the customers in telecommunication companies has led the researcher to the designing and development of software to handle the telephone, subscribers do complain of excessive billing and this has often been traced to the carelessness or otherwise on the part of the staff that prepare the bills. The carelessness of staff that results in the delay and stoppage of updating the customer’s bill account is another factor. Also, lack of working materials e.g. carbon sheets, stationeries and also laziness in the repairs of faulty machines is often complained about.

1.0     INTRODUCTION

A computer system is a grouping of functional devices which have electronic ; electrical, and mechanical features respectively and have the capacity to accept and store data for reference purpose through a recall or retrieval mechanism to present a feed back to its users and have the capacity for communications and resource sharing.

The progress in information revolution resulted in the use of computer in information management which have shown high efficiency rate, specifically in sales services. Sales can be defined as he exchange of goods and / or services for a price which can be money or other goods / service on the other hand, invoicing is an expression or word that can be substituted for sales, once a sale is made; details of the transaction are taken and documented in form of invoice. These Operations of sales can be done through writing and description of the transaction; this is called involving operation. Computerized invoicing system tries to reduce the problem of manual handling of sales. Such problems include: Inaccuracies in calculations, fine wastage and inefficiency in service delivery.

As regards to this topic, computer systems are used to record sales and issue invoice to customers which have put off the burden of manual handling of sales.

In Bubbles Plaza, the use of electronic digital communication through which multi-media is transmitted have tremendously increased speed, accuracy and total efficiency. Also have increasingly integrated an internal scope and impact in sale management.

DESIGN AND IMPLEMENTATION OF AN ENABLING VIRTUAL CLASSROOM AND TEXT-BASED E-LEARNING ENVIRONMENT FOR NIGERIAN POLYTECHNIC EDUCATION SYSTEM

ABSTRACT

The research project reported in this thesis has shown that there is need for an enabling virtual classroom and text-based E-learning environment in Nigerian Polytechnic Education System. Having identified the problems inherent in Nigerian Polytechnic Education System, A virtual classroom was designed that accommodated a blend of synchronous and Asynchronous methods of learning. Web accessibility initiative was incorporated in the design to take care of learners with some sort of disabilities. Also included, was a virtual library facility for referencing. The designed virtual classroom was used in practice to assist learners in undertaking courses in Computer Science, Banking and Finance, Business Administration and Management, Electrical/Electronics Engineering, Secretarial Studies and Mass Communication at National Diploma or Higher National Diploma levels using NBTE (National Board for Technical Education) minimum guide curriculum. HTML, DHTML, XML and Visual Basic (VB) authoring languages were used to produce the course wares. The authoring system was developed in a way that will enable lecturers who are not computer professionals to produce course wares without any serious computer programming skill. Visual Basic Programming Language was used to create the database used in this work.

The text-based facility was used to establish communication between the lecturer and the students and among themselves and even with authorities of the school.

Collaborative and didactic learning were supported by the newly designed system.

CHAPTER ONE

• INTRODUCTION

The use of computer in Education was nursed when the first business computer was completed in 1951. Educationalists dreamt of connecting College classrooms to computers which would serve as patient tutors, scrupulous examiners and tireless schedulers of instructions. Further, it was expected that the benefits to students would include the freedom to follow their own paths of learning, at their own pace at a time convenient to them, with richer materials to work with and automatic measurement of their progress.

The dream was actualized with the introduction of E-learning and its attendant virtual reality.

E-learning can be accomplished through any of the following:- web-based learning, virtual classroom, Distance learning etc.

E-learning involves the use of virtual reality in establishing a virtual classroom, virtual library and E-learning ware (or kernel or courseware) for actualizing collaborative and didactic learning.

The virtual classroom and text-based E-learning environment is internet-based. Its components include content delivery in multiple formats, management of the learning experience, and a networked community of learners, content developers and experts.

The design of a virtual classroom and text-based environment aims at providing flexible learning and develop appropriate framework for sharing good learning materials among polytechnics, self-learners and interested companies in different parts of the world.

It supports individualized higher education for young learners and supports life long learning for adults.

The actualization of an enabling E-learning environment involves the development of web-site through which access can be made to virtual library and courseware facilities and information about prospective E-learners.

The E-learning environment is text-based because E-mail facility is used to establish communication between the instructor and the E-learners. Other text based features like Addressing, Ellipses and signs were incorporated.

The design of E-learning environment accommodates a mix of synchronous and asynchronous methods of learning considering the fact that Nigeria has not fully embraced the digital revolution and also the poor funding nature of our polytechnic education system.

The designed system is user-friendly, interactive and has a feedback mechanism to ensure control and quality learning.

1.1     BACKGROUND OF STUDY

Database is a standard term covering computer based services, which provide information in response in specific requests from users. The data may stored in documents, microforms or computer code text and graphics (user interface) for references.

Database management as regards to personnel information system evaluate the process of managing and monitoring employee or members of an organization as a means of gaining maximum efficiency. As the organization benefit or offer to the public on subscription basis; the output services is either a physical document or computer data presented, say on a video display unit.

Further more, the information is data/stored to a disk; perhaps is when the user supplies then is to locate a copy of the document and deliver it to the user. More after than not, however information need are expressed or outputted in terms of request for data, such as how many employee are being eroded in the organization? Or what is the salary level of an employee? – To answer such question reference must be made to records such questions, reference must be made to records stored as the computer coded data. This involve searching and retrieval of records stored on disk.

SHORT HISTROY
