—XML has become the de facto standard for representing and interchanging data in web-based applications. And XML view, a virtual window for specified users, has been widely applied. In practical system, users encounter the so-called view update problem when they need update source data through the view. For a long time, the view update problem is an open question in database community. With the development of various data models, the corresponding view update problem has been widely researched. In this paper, we introduce the conception of view update problem. We survey and compare previous approaches. Especially, we emphasize the role of semantics. Focusing on the problem in XML context, we give a discussion and propose a framework, which collects the semantic information at view definition time. Some related techniques for implementing this framework are further introduced.
