Review

This paper describes XML-QL, a query language for XML. It also describes a data model for XML. XML-QL proposes to overcome the fundamental database problems of data extraction, integration, transportation and transformation. The presentation is clear and precise. It gives a good overview of the capabilities of XML-QL. The examples used helped clarify the points made, but in certain cases were slightly unclear (some of the variable bindings were not easily comprehensible). Following are a list of technical strengths and weaknesses of XML-QL as I see it.
