n-orm offers a simple persistence layer for Java. Targeted stores are "no-sql" as the framework assumes a column-oriented like storage data model. The framework makes use of annotations, and offers a very simple query language, simple enough to be very efficient, and too simple to let a model not to be efficient... ;-) Current stores are HBase, …
