SDO & SCA

Some of the most important J2EE vendors delivered the new version of the Service Data Objects (SDO) spec and the first version of Service Component Architecture (SCA). SDO is a great standard to abstract physical data sources and is the heart of J2EE products like BEA Aqualogic Data Services. About SCA I do like some concepts (like bindings and metadata representation) that are required in order to simplify the J2EE SOA approaches but on the other hand I truly think that other concepts present in the specification are not in sync with some of the basics SOA principles. I will be posting about this shortly.
