What is an example of an object-oriented DBMS?
An object-oriented database stores complex data as compared to relational database. Some examples of OODBMS are Versant Object Database, Objectivity/DB, ObjectStore, Caché and ZODB. Stands for Relational Database Management System.
Which of these is are the most important characteristics of OODBMS?
The main characteristic of objects in OODBMS is the possibility of user-constructed types. An object created in a project or application saves into a database as is. Object-oriented databases directly deal with data as complete objects.
What are the advantages of object-oriented database?
