Research And Implementation Of The Method Of Data Auditing Based On Auditing-Relationship Expression

With the development of competition in telecom markets, telecom operators have already realized that they should pay more attention to revenue management of company while keeping the development of services. In order to reduce revenue loss, the research on Revenue Assurance (RA) has been initiated. Data auditing is an effective method for RA. However, the current research of data auditing is just at the initial stage. It needs a theoretical foundation and a guiding method which is agreed on by all in the area of revenue assurance. With experiences of data auditing for a certain telecom operator, a new method for data auditing based on auditing-relationship expression is put forwarded in the paper. And based on the research of this method, a data auditing solution is detailed designed. The solution is also partially implemented and verified by a real example to get its practicability proved.The concept of auditing-relationship expression is first put forwarded. It is based on the constraints of data in the telecom operator's systems. The concept of auditing-relationship expression and data entity are formally defined and described from the business aspect. Based on the research, a method of data auditing for one single auditing-relationship expression is put forwarded. Then in the paper, the relationships of all the auditing-relationship expressions in system ms are studied and a method for handling these expressions is put forwarded so that all these expressions can be audited. A data auditing solution is detailed designed. The solution is based on the model of auditing-relationship expression and it contains information model, data model, schema, XML writing method, XML reading method. At last, the solution is partially implemented and verified by a real example from the practice of the telecom operator's data auditing so that its practicability is proved.
