h4. What is Service Data Object?
SOA creates an environment where different types of data must work together. This makes application development complex. Service Data Object(SDO), provides a very simple programming model that addresses this issue. The key high level advantages of SDO are:

* Uniform access to data from heterogeneous sources which could be XML, RDB, POJO, SOAP, etc.
* SDO provides both a static (or strongly typed) programming model and a dynamic (or loosely typed) programming model. This provides a simple programming model without sacrificing the dynamic model needed by tools and frameworks.
* Provides Meta-data for easy introspection of data types
* Supports a disconnected model, whereby data can be retrieved from a data source via [Data Access Service|http://incubator.apache.org/tuscany/das-overview.html]. The data can be modified by a client with change tracking, and applied back to the data source.
* SDO programming model is language neutral 

Tuscany implements SDO in [Java|SDO Java] and in [C++|SDO CPP]. A [PHP version of SDO|http://www.osoa.org/display/PHP/SOA+PHP+Homepage] is also available.

[SDO specification|http://www.osoa.org/display/Main/Service+Data+Objects+Specifications] can be found at the [Open Service Oriented Architecture website|http://osoa.org].
