Modularized design for wrappers/monitors in data warehouse systems

To simplify the task of constructing wrapper/monitor for the information sources in data warehouse systems, we provide a modularized design method to re-use the code. By substituting some parts of wrapper modules, we can re-use the wrapper on a dierent information source. For each information source, we also develop a toolkit to generate a corresponding monitor. By the method, we can reduce much eort to code the monitor component. We also develop a method to map the object-relational schema into relational one. The mapping method helps us make an uniform interface between wrapper and an integrator.
