Immediate and Partial Validation Mechanism for the Conflict Resolution of Update Operations in XML Databases

Recently, several researches have been performed for updating XML documents[1][2][12] stored in databases. These researches define update operations and resolve some semantic problems. However, because the update operations are usually validated after execution, conflicts can occur among them. Furthermore, in many studies for updating, they just validate whole XML documents and can’t validate parts of them. If updates are very frequent, validation will cause performance degradation. In this paper, we propose immediate and partial validation mechanism for these two problems
