Title:   XML Data Services: Data Modeling in the Web Services Era
Speaker: Michael J. Carey (BEA Systems, Inc.)

Abstract:

Once upon a time the world was simple.  There were tables, views, stored
procedures, and client/server interfaces.  Data was modeled using
time-honored E-R modeling techniques, mapped methodically into tables in
the corporate database, and then queried using SQL.  Applications were
built, not bought.  DBAs and application developers ruled.  Life was
good...

Fast forward to the present day, and the world is no longer simple.
Data is strewn everywhere - it's in multiple databases of various shapes
and sizes, trapped inside a variety of applications, fronted by web
services, living in files - and unfortunately, it's all relevant, so we
can't just ignore it.  Core applications are more often bought than
built, and new enterprise applications are built by composing and
orchestrating the functions provided by these component applications.
And, of course, Service-Oriented Architectures (SOA) are all the rage.
Now what?

This talk will discuss the role of data in the emerging SOA world and
the present day technologies that are causing problems and offering
solutions.  The talk will make the case for XML data services, a new
approach to integrating data and services into a single "data
model-able" framework.  It will describe BEA's implementation of data
services, coming in the next major release of Liquid Data for WebLogic,
describing the software platform and tools that we have built (based on
XML technologies such as XML Schema and XQuery) to enable developers to
easily and declaratively build, deploy, and manage data services.
