SODA A Distributed Data Management Framework for the Internet of Services

SODA (Service Oriented Database Architecture) is a proof-of-concept prototype middleware implementation for data intensive applications, where data of relevance is stored at multiple locations over the Internet. Because of its modularity the used Web Services can be plugged together very easily, almost in a LEGO alike manner. In fact these services provide the business logic for distributed query execution, specifically supporting autonomous databases in heterogeneous environments. Operations used in this framework - like selection, projection, join, product or sort - can be orchestrated (used, added and removed) dynamically. The architecture is based on the WSRF standard and thus supports stateful Web Services. For reasons of portability it is implemented in Java and uses the WSRF-compatible Apache Muse library.
