Questions tagged [hibernate-ogm]

Hibernate Object/Grid Mapper (OGM) provides Java Persistence (JPA) support for NoSQL solutions. It reuses Hibernate Core's engine but persists entities into a NoSQL data store instead of a relational database. It allows applications to continue to use Java Persistence Query Language (and Hibernate HQL extensions) to search their data.

From Hibernate OGM Reference Guide Hibernate OGM offers a familiar programming paradigm to deal with NoSQL stores, moves model denormalization from a manual imperative work to a declarative approach handled by the engine and encourages new data usage patterns and NoSQL exploration in more "traditional" enterprises

Hibernate OGM also aims at helping people scale traditional relational databases by providing a NoSQL front-end and keeping the same JPA APIs and domain model.
