A Bridge Between ISO/IEC SQL and W3C XML Activities
The fusion of SQL and Extensible Markup Language (XML)
involved veterans of the software industry, including Jim Melton
of Oracle Corporation. Jim wears many hats these days.
Besides advancing the SQL and XQuery standards, Jim is also working on
XQJ, the XQuery API for Java. His role as Standards Architect at Oracle
includes creating specifications with consortia and de jure standards
organizations. Jim is also an author of several books about SQL and databases.
Editor of the
International SQL Standard
Besides contributing to specifications published by the
World Wide Web Consortium (W3C), Jim has been the editor of the international SQL standard for twenty years.
Many important standards come from the International Organization for
Standardization (ISO) and the International Electrotechnical Commission (IEC).
The SQL:1999 standard, for example, is an ISO/IEC standard. The W3C's XML
Activity has produced several important specifications, including XML and
Paul Cotton is another long-time veteran of SQL standards activities. After
the W3C held its first XML query workshop in 1998, Paul and Jim Melton
became actively involved in developing the W3C's XML query language (XQuery).
Jim Melton has been a key participant in bringing SQL and XML together.
Today he is an active participant in work being done by the
InterNational Committee for Information Technology Standards (INCITS). An
INCITS task group acts as a bridge between the SQL efforts of ISO/IEC and the XML
work of the W3C. In creating the SQL:2003 standard, INCITS
added support for operating with XML data.
Besides working on updates to SQL standards,
Jim has remained active in the advancement of the W3C XQuery standard. The
development cycle for XQuery 1.0 began about five years ago. Members of
the XML Query working group developed a data model and query algebra, use
cases, and a formal specification for the XQuery language.
In an interview recorded in Silicon Valley, Jim discusses the
effort to bring SQL and
XML together. He also discusses XQuery and the proliferation of
organizations publishing de facto or de jure
