| | | | | In the world of Java development, one topic that has sparked debate and frustration for many developers is Object-Relational Mapping (ORM). ORM is a technique used to bridge the gap between object-oriented programming languages, such as Java, and relational databases, like MySQL or PostgreSQL. The purpose of ORM is to simplify the data access layer and eliminate the need for developers to write raw SQL queries. However, a recent text expressing strong criticism of ORM on Java, particularly Hibernate, has garnered attention among developers. The author claims that ORM, in general, has always been a disappointing solution. One of the arguments presented is that the ability to use different databases, which was once touted as a selling point of ORM, is a feature that is rarely utilized in practice. Furthermore, the claim that developers don't need to know SQL while using ORM is dismissed as false, as modifying queries at the string level is often necessary in non-trivial applications. | |
