I intend to develop a small (Java) application for managing my finances. I believe I need to use an embedded database, but I have no experience regarding this issue. I tried to look at some of the available products, but I can't decide which one would be more suitable for me. H2, HSQLDB, Derby and Berkeley DB seem to be good candidates, but I still don't see how they compare to each other. I appreciate your help comparing them and helping me decide which one to use.
I intend to use Hibernate for my application (unless you would recommend using DBMS-provided API), but I also want to have the ability to edit the database easily using a SQL browsing tool (modifying schema and changing data).
Thank you.

A few of the dominant providers are H2, HyperSQL, Apache Derby, Berkley DB, Java DB, ObjectDB, and so forth. HyperSQL conforms to the SQL:2011 standard and JDBC 4 specification and supports every classical feature expected from a modern relational database.
Mainly, H2 database can be configured to run as inmemory database, which means that data will not persist on the disk. Because of embedded database it is not used for production development, but mostly used for development and testing.
HSQLDB (HyperSQL Database) HSQLDB is an open source project, also written in Java, representing a relational database. It follows the SQL and JDBC standards and supports SQL features such as stored procedures and triggers. It can be used in the in-memory mode, or it can be configured to use disk storage.

Which one you use is up to you, depending how much performance and how much stability you need.
The developer of H2 has put up a nice performance evaluation:
