Service Data Objects (SDOs) have become a foundation technology for Service
Oriented Architecture (SOA). Recently, BEA, IBM, Oracle, SAP, Iona, Siebel,
and Sybase announced their support for an SOA-enabling framework
specification named Service Component Architecture (SCA). SD O provides the
primary data representation in this framework.
Although not addressed by the current SDO or SCA specifications, there's a
definite need for a generic data access service that operates in terms of
SDOs. The alternative to this service would be the tedious and error-prone
development of a custom mapping between the back-end data representation and
Service Data Objects.
The Relational Database Data Access Service (RDB DAS) obviates the need for
this custom development by providing a ro... (more)
Late last year, IBM Corp., and BEA Systems, Inc., introduced Service Data
Objects (SDO), a new data programming specification that complements existing
Java 2 Enterprise Edition technologies and enables service-oriented
architectures by providing uniform data access for a wide variety of service
and resource types. Not only does SDO enable a consistent approach to data
access, but it als... (more)
