Warning: My opinion only Unql seemed to be especially pointless. Being somewhat compatible with SQL syntax made no sense - SQL syntax and all the tools using it assume the relational model and simple table like data layouts. NoSQL databases vary, but generally they are non-relational and schemaless, and JSON interoperable ones have a structure completely different than SQL tables (eg item nesting). Every NoSQL database already has its own query mechanism so Unql would always be a second class citizen if any of them ever adopted Unql. NoSQL databases also tend to have looser consistency, have multiple servers available and various other semantics very different than SQL servers. The native NoSQL interfaces expose and work with those semantics. Cassandra did actually end up with something SQL inspired: http://cassandra.apache.org/doc/cql/CQL.html Riak uses something like Google advanced searches (field:value): http://docs.basho.com/riak/latest/cookbooks/Riak-Search---Querying/ MongoDB uses JSON with extra magic operators: http://docs.mongodb.org/manual/applications/read/ Personally I like MongoDB approach where queries strongly resemble the underlying stored data which means very little translation between the two.
