With XML emerging as the data format of the Internet era, there is a substantial increase in the amount of data encoded in XML. However, the majority of everyday data is still stored and maintained in relational databases. Therefore, the authors expect the needs to convert such relational data into XML documents will grow substantially as well. Two conversion algorithms, called NeT and CoT, to translate relational schemas to XML schemas using various semantic constraints are presented. The authors first present a language-independent formalism named XSchema so that the algorithms are able to generate output schema in various XML schema language proposals.
