eXcelon exclaims XSLT tool, XIS updates
- By Jack Vaughan
XML specialist eXcelon Corp. this week announced release 4.5 of its Stylus
Studio XSLT IDE that lets developers work in a WYSIWYG environment to convert
HTML pages to XSLT style sheets. It includes an XQuery editor and debugger that
helps development team members learn XQuery with step-by-step debugging and a
display of variable values. Also due from eXcelon is a new version of its XIS
native XML database server.
The XIS 3.1.2 server supports development of systems that use the emerging
XQuery standard to access, query and audit XML documents. The update is also
said to deliver better speed, as well as .NET support that allows systems to
share XML documents between .NET and J2EE architectures.
XQuery could have a profound effect on the course of XML. It addresses some
issues that stand as obstacles to greater XML deployment. While XQuery
techniques are also available to RDB deployers, XQuery for some relational
configurations requires systems to pull entire documents out of memory before
launching a query, said an eXcelon representative. And this creates issues.
''We see some new Web services-related documents containing 30-Mbyte messages.
They are huge. People don't want to have to pull down entire documents [of this
size] in order to do a query,'' said Larry Alston, eXcelon's executive vice
president. eXcelon has further helped the querying masses in this release with
support for full Verity text search of XML documents, he noted.
A major benefit of XQuery is that it brings greater standardization to XML
data handling. But as it is also set to be available to SQL RDBMS makers who
have added XML handling abilities (often via ''shredding'' and ''BLOBing'' methods)
to their systems, and given that even deeper XML/RDB links may be on the way,
Alston was asked where native XML stores would still gain favor.
''People that need highly granular and extensible data handling will find a
good fit,'' said Alston. Systems that center on many types of common corporate
documents could meet these requirements, he said, noting mortgage applications,
insurance claims, product catalogs and patient care systems as examples.
