An one-to-one model for audit trails construction in database design

摘要

The clear and complete audit trails of a transaction system are important to auditing, management and control. In the environment of manual operation, the data created during the transaction process are all written down on papers and account books; in other words, the audit trails are composed of a group of reference codes on the original documents. Hence, all the processing trails are visible and checkable. However, after the data processing environment has been changed from manual operation to computerised operation, the audit trails have become not only invisible due to the electronic data, but also ambiguous due to the special characteristics of database design principles. This paper found that the characteristics of database would be affected by 'control constructs' and their 'one to one' manipulated values ofthe data model, and then presents an OTO model. Finally, a simple simulated ease is prepared for illustration ofthe OTO model.
