Re: Schema Mapping Tools

Thanks Carl, I am working on something related to that (arent we all?)

Chamindra, I think to answer your question, you may have to establish
what kind of schemas you want to map

If we are talking about database schemas, thats one thing - from the
documentation posted here it looks like that's the case. I think all
database managment systems such as oracle
have database mapping functionalities, and I am sure there must be some OS
ones

lots of other tools are available, best suited to the type of schema that is
being matched
such as xml, or rdf etc but I am not sure that's what you are looking for

please let us know when you find out
