2.0 LITERATURE REVIEW
According to Andeson (1987), quoted by Jimoh Fatimo(2002) described data processing as a concerned with the systematic recording arranging, filing, processing and processing dissemination of facts relating to the physical event that occur in organization.
Fatoki M.S. (1985); quoted by Ibrahim (1990) and Jimoh Fatimo(2002) defined data processing as the act of collecting data analyzing data in such a way that they become information.
Billing technique, according to lawal bolanle M. (1995) defined it is the processing bills from customers.
While Jimoh Fatimo (2002) defined billing technique as the method of paying for service rendered or process where standard momentary payment are made for services rendered. It could be done suing manual method or electric computer.
Existing system simply means the old system use in preparing bill to customer at NITEL PLC. Which is manual system.
With this method, processing is done by keeping each customers record in a file (master File). Each customer record is kept in a particular file and on a form. There is each blank form which show all the information pertaining to each customers meter that the manage will file and send it to the account.
Among the information on the form are name of the subscribers, nationality of the subscribers, data collecting meter, address of the subscribers and their telephone number.
When accounts have seen that all the data has been entered correctly on the form, signature will be assigned and it will be released to customers as bill.
Since the manual method is solely carried out by human brain, there is tendency of problem to arise this includes.
1. Time Consuming: Manual method takes along process before customers could be given bill and waste much of customers’ time.
2. Fraudness: This method gives room for making and obtaining meter illegally.
3. Labor Intensity: During the process, the manager will have to go from and have to another which may result of fatigue.
4. Inaccuracy
2.3 SOLUTION TO THE PROBLEM
The only reliable solution to all the problem stated above is the use of computer machine in billing system.
Among the various area where the use o computer provide solution to the problem confronting manual method include:
1. Time Saving: Computer is very fast in operation and billions of data can be processed in a very short period of time. The rate at which bills will be produced will be easy and faster then manual method.
2. Security: Unlike manual method, there is security of information record keeping which pertain to meters subscribers with the use of computer. It restrict unauthorized used to have access to stored information.
3. Accuracy: With the aid of computer in preparing bills there will be rapt accuracy error free in billing system.
4. There will be a limitation to energy consuming by the labours.
2.4 DESCRIPTION OF THE PROPOSED SYSTEM
The proposed system based on computerization that preparation of bills with the aid of computer machine.
Computer is any machine or device that under the control of stored program which can accept data in prescribed form, process the data and supply the result as information in a specified format.
The proposed system of billing system is developed through access software package that will accept the record of each customer or subscribers and make it possible to update or edit the record and also deletion of the record.
The program is written in such a way that it has different modulus. The program describes how registration and payment of the customer or subscriber can be done: calculation of bills can be correctly done.
Speed: Computer can perform amount of calculation at very fast speed.
Accuracy: results or calculation done by computer are very neat and error free.
Reliability: Any operation carried out by computer can be relief upon any time, anyway and anywhere.
Storage Capacity: Computer has the store a very large amount of data in its internal and external memory.
Security Purpose: All information or records of customers or subscribes stored in the computer for processing are obtain the use of password.
The billing procedure is carried out in the account section of NITEL name protocol applies to almost all the serious concerning billing.
Since NITEL has a record of the service rendered to the subscriber his effect the billing.
The procedure is applicable to both private and business time users. Each time user has a separate meter that reads whenever the service to telephone or telex is subjected to usage. When billing is done, the various meter are red to know the number of unit used for the previous reading from the current reading which is record on the meter form.
There are two method of reading meter, we have
a. Physical Reading: Physical reading is a face to face reading for instance using their eyes.
b. Shooting: Shooting is the process where by telephone meter readers are produced with cameras thereafter the telephone meters are shooting for every billing period. This is because the meters are very small and the figure on it are very minute and it does involve a lot of straining before the meters can be read. After the film is taken and made into a negation that is later developed, the meter readers generally submit the films to the business office that later works on it.
