On Object Oriented Database Management System (ODBMS) integrates object programming language capabilities with database capabilities. It makes objects appear as programming language objects; it extends the language with transparently persistent data, concurrency control, data recovery, associative queries, and other database capabilities.
Object Database Management System. Combines encapsulation and inheritance with the database concepts of permanence, sharing, reliability, consistency and associative retrieval. An internal identifier is assigned to each object. Relationships are implemented using these internal identifiers. Any change to a key value is thus seen by all other related objects, unlike relational systems.
