A hypertext view is a derived hypertext for a given database. We are interested in providing a mechanism of translating hypertext view update operations to appropriate data manipulation operations in database. However, given a hypertext view update operation, we cannot always uniquely determine what needs to be done in terms of database operations to perform the intended hypertext view update operation. Therefore, the goal of this study is to identify ambiguities that arise in the translation mechanism and investigate how link information (i.e., static link information such as links in hypertext and dynamic information such as traversals) can be used in resolving the ambiguities. We provide update semantics for each of the hypertext view update operations and show how the ambiguities can be resolved with link information.
