  Abstract:  Abstract. The most critical disadvantage of the Change Data Capture functionality provided by the relational database management systems is the impossibility to add custom, application-specific data to the log. In this paper an approach is proposed how to implement custom, application- specific Change Data Capture functionality with the help of database triggers and O/RM framework. There are listed clear problem requirements and concrete steps are proposed how to resolve it. The two layers of the solution are identified and described database level and application level. All details of the solution are provided with example source code. It is also suggested an approach for quality assurance of the solution.
