Which of the following is disadvantage of Oodb?
There are following disadvantages of OODBMSs: Lack of universal data model: There is no universally agreed data model for an OODBMS, and most models lack a theoretical foundation. This . disadvantage is seen as a significant drawback, and is comparable to per-relational systems.
Why is Oodb not popular?
Yet another reason why there is not such a strong push for OODBMS is that there is “poor man’s OODBMS” solution — ORMs. This has gained huge popularity, as they are backed by well known, stable and tested DB engines, yet they provide the mapping to objects. Of course, these are not true OODBs.

Drawbacks of Object Databases
- Object databases are not as popular as RDBMS. It is difficult to find object DB developers.
- Not many programming language support object databases.
- RDBMS have SQL as a standard query language.
- Object databases are difficult to learn for non-programmers.

What are the benefits of Ordbms?
There are following advantages of ORDBMSs: Reuse and Sharing: The main advantages of extending the Relational data model come from reuse and sharing. Reuse comes from the ability to extend the DBMS server to perform standard functionality centrally, rather than have it coded in each application.
