What are the differences between JDBC and ORM?
JDBC (Java Database Connectivity) is a low-level API for connecting to databases, while ORM (Object-Relational Mapping) frameworks like Hibernate provide a higher-level abstraction to interact with databases using objects.
Can you explain how ORM simplifies database interactions?
ORM simplifies database interactions by allowing developers to work with objects instead of SQL queries, automatically handling the conversion between database tables and application objects.
Are there any performance drawbacks to using ORM?
Yes, ORM can introduce some performance overhead due to the abstraction layer, which may lead to less optimized SQL queries compared to hand-written JDBC code.
When should I choose JDBC over ORM?
You should choose JDBC over ORM when you need fine-grained control over SQL queries, require high performance, or are working on a simple application where the overhead of ORM isn't justified.
