I am developing a Java Desktop Application and want a light database that can be used with Hibernate and that can be packed with an application.
I was going to use Derby database. It's size is near 2 MB. But before that I wanted to have views of experts on SO.
Will it work with Hibernate?
Actually, I am new to Hibernate and was studying that it requires a Dialect for a database so Is Hibernate has dialect for Derby?
JavaDB (Sun's supported distribution of the open source Apache Derby), HSQLDB (not very active) and H2 (the successor of HSQLDB) are all 100% Java embeddable database engines and can all be used with Hibernate (i.e. there are dialect for them). Refer to this page and this one.
HSQLDB has the smallest footprint (~700 KB) of all of them. But feature wise (see this comparison), H2 is the clear winner and its footprint (~1 MB) is still smaller than Derby's one (~2 MB).
The final choice depends on what you need but H2 is a good compromise of features and size (in other words, a big competitor). Have a look at the mentioned comparison.
I would recommend HSQLDB. It is small and fast and runs fine with Hibernate. Hibernate has a dialect for the Derby DB as well (haven't used it though and I think it is not officially supported by Hibernate yet).
Another Alternative would be SQLite.
You can also try Firebird
There is an embedded version and a client/server mode version
