How do you implement ORM?
Efficient Implement of ORM (Object/Relational Mapping) Use in J2EE Framework: Hibernate. Abstract: Object-relational mapping (ORM) in computer software is a programming technique for converting data between incompatible type systems in relational databases and object-oriented programming languages.
Is MongoDB a ORM?
Using MongoDB removes the complex object-relational mapping (ORM) layer that translates objects in code to relational tables. MongoDB’s flexible data model also means that your database schema can evolve with business requirements.
Where is ORM used?
Object–relational mapping (ORM, O/RM, and O/R mapping tool) in computer science is a programming technique for converting data between incompatible type systems using object-oriented programming languages. This creates, in effect, a “virtual object database” that can be used from within the programming language.

- ORM has a tendency to be slow.
- ORM fail to compete against SQL queries for complex queries.
