摘要
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 different information source. For each information source, we also develop a toolkit to generate a corresponding monitor. By the method, we can reduce much effort 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. (C) 2000 Elsevier Science Inc. All rights reserved.
