The database to be an ODBMS must satisfy two criteria. Data integration: The heterogeneous data sources are merged into a single data source. Adaptation of the object-oriented programming paradigm (e.g., Smalltalk, C++) to database systems. Object databases are different from relational databases which are table-oriented. First set contains 8 rules that define that it is an Object-Oriented and second set contains 5 rules that define that it is a DBMS. An Example of the Object Oriented data model is − PERSON and EMPLOYEE are 2 objects in this model. Objects are classified as simple, composite, compound, hybrid or associative. It picks up each thing/object in the real world which is involved in the requirement. Conceptually, all interactions between an object and the rest of the system are via messages. An object-oriented database (OODB) stores data in objects. 3. A Database model defines the logical design and structure of a database and defines how data will be stored, accessed and updated in a database management system.
