Trackback Added: SOA and Data Architecture ; A data access tier is an architectural component of many systems designs. Reusable data objects are a fundamental building block for SOA. Yet many architects are ignoring the data tier for SOA.

The adoption of Service Oriented Architecture (SOA) promises to further decouple monolithic applications by decomposing business functions and processes into discrete services. While this makes enterprise computing assets more accessible and reusable, SOA implementation patterns are primarily an iteration over previous application development models. Like most application development evolutions, SOA approaches inject more layers and flexibility into the application tier, but have often neglected the most fundamental building block of all applications: the underlying data.
