Nowadays, many organizations face the problem of how to accessing the legacy data by means of flexible mechanism. As a powerful and efficient solution to this problem, ontology-based data access (OBDA) technology enables people to utilize data from heterogeneous sources through a well-defined ontology. However, under the dynamic environment, the ontology which acts as concept view in an OBDA application may be changed and modified to meet users' needs. Furthermore, the changes occurred during ontology evolution process may be propagated across the whole system. In order to minimize the influence of ontology evolution in OBDA system, we present a solution to control the impact of change propagation from ontology evolution, namely ICOE method. The experiment illustrate that this method is helpful in managing an OBDA system.
