Julian Ford points out an article at DMReview entitled "Web
Services: Fulfilling a Spectrum of Business Intelligence Needs".
Written by Dan Everett at Hyperion, it talks about the move within the
BI marketplace to expose application functionality through APIs to as a
service to other applications, using
Web Services technologies such as
introduction of Web Services functionality promises to address a
traditional limitation with HTTP-based BI tools, in that the HTTP
stateless and users normally require a persistent connection when
carrying out OLAP analysis. Oracle have dealt with this in the past
through either thick-client java applet techologies (as with Discoverer
Plus) or through java servlets and cookies (as with Discoverer Viewer,
or Reports when using 9iAS and SSO).
introduction of web services technology promises to open up the
functionality of tools such as Discoverer and Reports so that it can be
used by a range of applications, and indeed Oracle are some way to
achieving this objective with Oracle Reports, as this
tutorial over at OTN demonstrates.
