What ORMs have you used? When Hibernate, when JDBC? Were Liquibase/Flyway used?

In my practice, I have used Hibernate for projects where rapid development with rich ORM functionality is important, especially when working with an object-oriented model and complex entity relationships. I used JDBC in cases where maximum control over SQL queries, performance optimization, or working with non-standard queries was required.

I used Liquibase and Flyway for database migration management. I prefer Flyway for its simplicity and integration with CI/CD, while Liquibase is chosen when more complex migration scenarios with rollback capabilities and report generation are needed.

An example of using Flyway in a Maven project:

<plugin>
  <groupId>org.flywaydb</groupId>
  <artifactId>flyway-maven-plugin</artifactId>
  <version>7.5.4</version>
  <configuration>
    <url>jdbc:postgresql://localhost:5432/mydb</url>
    <user>user</user>
    <password>password</password>
  </configuration>
</plugin>

This approach allows reliable management of database schema versioning.
