1) (i) INTRODUCTION OF THE PROJECT
The purpose of the project is to present the requirement of the Computerization of Telephone Billing System. The project thus calculates the telephone bills automatically. It does almost every work which is related to automatic telephone billing connection system via- new connection , customer record modification, viewing customer records & all works related to rate of bills, meter readings in addition to bill calculation and bill generation. “Telephone Billing System ” is developed as per seeing the increasing requirement to speed up the work and incorporate a new work culture. Thus a new software has been proposed to reduce manual work, improving work efficiency, saving time and to provide greater flexibility and user-friendliness as the system previously followed was totally manual one with lots of errors.
1) (ii)OBJECTIVE OF THE PROJECT
The main objective while implementing the project Telephone Billing System were to minimize the work and at the same time increase the speed of the work done.
This new system is built with the following objective:
1) Information retrieval will become easy.
2) Maintenance of database as well as overall project will become easy.
3) Security measure will be adopted, by maintaining the login of username and the password.
4) Data redundancy will be greatly reduced because this new system is built using Visual Basic 6.0 as front-end. It entails looking into duplication of efforts , bottlenecks and inefficient existing procedures
2) (i) INTRODUCTION
System analysis is the performance management and documentation of activities related to the four life cycle phases of any software namely:
• The Study Phase
• The Design Phase
• The Development Phase
• The Operators Phase
System analysis is a vast field of study through which system analyst puts his thoughts and searches for the solution of problem. He has to get a clear idea of what he has in hand and what he has to produce. He has to extract the essence of expectations. He has to satisfy the user in the very possible way. System analysis needs and should include the following steps of study:
Study of current methods, the basic inputs available and output desired.
The splitting of a variable inputs into (.dbf) files so as to reduce redundancy and increase consistency.
Give the idea of key – field (if any) .
Ideas regarding code generation.
Software Analysis starts with a preliminary analysis and later switches on to a detailed one. During the preliminary analysis the Analyst takes a quick look at what is needed and whether the cost benefits. Detailed analysis studies in depth all the cornered factors, which builds and strengthens the software.
A system study is a step-by-step process used to identify and then developed the software needed to control the processing of specific application. System study is also known as SDLC (Software Development Life Cycle).
Steps of SDLC are:
1. Problem Definition
2. Feasibility Study
3. System Analysis
4. System Design
6. Post Implementation
2) (ii) EXISTING SYSTEM
The existing system was a manual one. Whatever be the process involved in the system were done through register (files) . There were lots of complexities involved in the system. When any customer takes new connections then separate files were maintained. Updating of data was very tedious job. It was not easy to do several administrative works like managing rates of calls, addition or modification of metered calls & customer entries.
2) (iii) DRAWBACKS OF EXISTING SYSTEM
In the existing system all the office works was done manually. The manual work processes was time consuming and hence slow. Following are the main drawbacks of the existing system:
The existing system is totally manual thus there are chances of error in processing.
The basic and major drawbacks in the existing system are the speed of retrieval of data from files, which leads to delay.
Maintenance of voluminous data is very cumbersome and laborious job.
The manual jobs such as calculation are more error prone.
There are plenty of chances of duplicity of data and information.
Updating is very tedious job.
There is no central database from where one can get different statistical data at one place.
The above facts, figures and drawbacks clearly indicate that there is need for computerization and thus decided to computerize the “TELEPHONE BILLING SYSTEM”. Since the existing system was totally manual which has lots of complexities, shortcomings in itself and all the data was being stored in registers, files etc thus to overcome the limitation of the existing system, the new computerized system was needed, so that information can be provided to the user more quickly, easily and more accurately.
2)(iv) PROPOSED SYSTEM
The new system titled “TELEPHONE BILLING SYSTEM” was hence proposed to remove all the drawbacks discussed above.
Information is a vital ingredient for the operation and management of any organization. Thus any system should have the ability to provide error free filtered information after processing the required data. This system has been taken up with a view for developing a more sophisticated system that can be easily handled by any kind of users. The proposed system aims at efficient and timely information for decision-making, integrate with other functions, and reduce redundant work.
