"OpenLink Virtuoso supports SPARQL embedded into SQL for querying RDF data stored in Virtuoso's database. SPARQL benefits from low-level support in the engine itself, such as SPARQL-aware type-casting rules and a dedicated IRI data type." Support ever conceivable database access system, including ODBC, JDBC, ADO .Net, REST, SOAP and WebDAV. wonder how it scales?
EoD SQL is a very small API (the JAR file weighs in at about 70k) that allows binding of SQL Queries to Java Objects. The API is designed to be compatible with the "Ease of Development" API that could be found in J2SE 1.6 beta, but not in the final release. The EoD API's main principal is that it maps SQL ResultSet's to objects, and not the other way around. Most OR mapping layers try to replicate the database structure in objects, where EoD SQL lets you write the SQL code, while it allows for easy access to Java Objects that map to the ResultSet.
a bug db stack integrating rdbms, xml and RDf storage and the like. java-ish and .netish, but has "bridges" to other languages. ridiculously many features, protocols and and open source versions. wish i had time to play. i don't.
