Hi Shmuel, SDO does not provide any interfaces to plug in a DAS. Instead, it just provides the low level features that allow, among others, disconnected-data applications (e.g., DAS like apps) to be built on top of it. In fact, the latest version of SDO being worked on at OASIS (SDO 3) doesn't mention DAS anymore, it simply refers more generally to "persistence services", of which DAS could be one. Standardization of a formal DAS spec doesn't seem to have gained very much traction, although I believe DAS is still being informally discussed by a few companies at OSOA (not OASIS).
