Hello experts,

I am trying to find out if hibernate reverse engineering is compulsory when using Hibernate ?

Currently, I am experimenting with Hibernate with EclipseLink JPA in Tomcat using Eclipse Mars.

Any infor would be using.

No it is not. You can go from the outside in, the inside out, or meet in the middle.

I have known people who defined the schema strictly from ORM annotations and used Hibernate's ability to instantiate tables on startup. For myself, I usually inherit an existing database, so I have to reverse-engineer at the beginning. Traditionally I've used OpenJPA's tools for that, but that's because before JPA was a standard I worked with Kodo JDO and the OpenJPA tools are descended from the JDO tools, so I'm comfortable with them.
