>I would like to know if there is a Java library that creates a >relational schema from an XML DTD or a Java library that parses >an XML DTD? The latter: http://www.javareport.com/html/products/prod_rev.shtml has a review of the popular Java XML parsers. The article admitted to being out-of-date as soon as it was printed, so most of the parsers have been updated since being reviewed. The former: part of the point of XML and SGML is their ability to indicate structure in data that doesn't fit neatly into normalized rows and tables. The information is structured hierarchically. I know that Information Builders, a former employer of mine (and Chet Ensign's), has products that map schema back and forth between relational databases and their hierarchically-based database products, so the algorithms exist, but it's not trivial. I haven't heard of anything that does this with DTDs, but it would be cool.
