 * Common interface to those mappings that are used to map JPA Embedded objects.
 *  - ElementCollection {@literal ->} AggregateCollectionMapping
 *  - Embedded {@literal ->} AggregateObjectMapping
 *
 * This interface was build to ease the metadata processing, namely to avoid
 * costly casting between the mappings above since their common parent is
 * DatabaseMapping.
