There's plenty of database systems that either don't support SQL at all, or support it with a range of other languages. One of SQL's remaining powers over most other options is the ability of non-expert users to construct their own ad-hoc reports. This is a big part of why Hadoop has Hive, which incorporates a very SQL-like language, and most other "big data" tools have something similar.
