Abstract

Services Oriented Architecture (SOA) has become a popular approach towards 
structuring information systems, and both RESTful and SOAP/WSDL-based Web 
Services have come popular technologies for enabling that approach. But too 
often, SOA seems to be "the architecture that forgot about data". Data 
is the longest-lived portion of most information systems, and is shared, 
queried, locked, modified, reused, repurposed, transformed, and interpreted in a 
wide variety of ways as it flows between services. But how do we track these 
interrelationships? And how should "data services" be designed?

A variety of specifications in the WS-* stack have been created to address the 
problem of "data in an SOA": from WS-Addressing and reference 
properties, to WS-ResourceFramework, which aims to enable access of both 
computational and data resources for "grid" or "cloud" 
computing. Meanwhile, the Web's REST Architecture offers a wildly successful 
model to identifying and representing data that could also be adapted for a 
company's internal information systems, and SQL services continue to support 
most reporting and analytic applications.

This session explores these topics for practitioners: how to choose an 
architectural style to support data services, the tradeoffs between SQL, 
WS-Addressing, WS-ResourceFramework and RESTful data services, and practical 
examples of designing data services and data-aware service registries, in both 
SOAP and REST.
