Post-Relational Database

Post-relational refers to databases intended to support an alternative logical data model to the transaction processing oriented relational model. Databases developed after the initial relational database. When data is modeled and stored in a format that differs substantially from the relational model of relations and primary and foreign keys, then the database can be characterized as a post-relational database. Examples include multidimensional databases, column databases, object-relational databases, flat file databases and others.
