Hibernate Difference Between ORM and JDBC (original) (raw)
Last Updated : 23 Mar, 2026
ORM (Object Relational Mapping) and JDBC are two approaches used to interact with databases in Java. JDBC is a low-level API where developers write SQL and manage data manually, while ORM (used by frameworks like Hibernate) works with objects and automatically maps them to database tables.
- ORM works with objects, whereas JDBC works with tables and SQL queries.
- JDBC requires manual coding, while ORM automates most database operations.
- ORM is preferred for complex applications, JDBC for simpler ones.
ORM (Object-Relational Mapping)
ORM is a technique that maps Java objects to database tables, allowing developers to interact with the database using object-oriented concepts instead of SQL. It reduces the complexity of handling data and improves code maintainability.
- Automatically converts objects into database records and vice versa.
- Reduces boilerplate code and improves development speed.
- Handles complex relationships like one-to-many and many-to-many easily.
JDBC (Java Database Connectivity)
JDBC is a Java API used to connect with databases and execute SQL queries directly. It provides full control over database operations but requires more manual coding and effort.
- Requires explicit SQL queries for all database operations.
- Provides direct and faster interaction with the database.
- Needs manual handling of connections, queries, and result sets.
Difference Between ORM and JDBC
The following Table describe the differences:
| Object Relational Mapping | Java Database Connectivity |
|---|---|
| Little slower than JDBC | It is faster compared to ORM |
| SQL queries requirement is comparatively quite less however this doesn't mean that you have to do less work using ORM | SQL queries are required here |
| Hibernate framework (working on ORM technology) makes it easy to store objects/data to database automatically without writing manual code | We have to write code manually to store objects/ data in the database |
| The flow from Object/data to hibernate i.e. the frontend part is based on the ORM technique | Whereas when the data is stored in the database finally i.e., the backend part is still based on JDBCin |
| There are not many restrictions while dealing with data. Even a single database cell can be retrieved, changed, and saved. | JDBC comes with a lot of restrictions on extracting the result-set, processing it, and then committing it back to the database. |
