3. Representative Products
While the general world of document management is moving toward adoption
of structured information and use of XML and SGML, three providers stand
out today:
-
Interleaf: Interleaf's product, BladeRunner, is described at the Interleaf web site.
-
Chrystal Software: Chrystal's product, Astoria, is described
at the Chrystal web site.
-
Poet Software: Poet's product, Poet Content Management Suite,
is described at the Poet web site.
The preceding offerings distinguish themselves by using underlying database
management products with native support for object-oriented data.
Object-oriented data, as mentioned in an earlier article of this series,
matches the structure of XML data quite well, and database systems that
comprehend object-oriented data adapt well to the tasks of managing XML
information.
By contrast, other information management products that comprehend
XML or SGML data use relational database systems and provide their own
object-oriented extensions to those database systems in order to comprehend
object-oriented data such as XML or SGML data, and relying on such
implementations have also garnered success and respect in the document
management marketplace. These providers' current
offerings fall into this second category:
-
Documentum: Documentum's products are described at the
Documentum web site.
-
Xyvision: Xyvision's family of Parlance Document Management
products are described at the
Xyvision web site .
