Which Embedded Database Is Best for a Small Financial Application: H2, HSQLDB, Derby, or Berkeley DB?

Comparison of Java Embedded Databases

When considering an embedded database for a small financial management application, several options present themselves, including H2, HSQLDB, Derby, and Berkeley DB. To determine the most suitable choice, let's examine their key features.

H2 and HSQLDB

Both H2 and HSQLDB combine ease of use and stability. HSQLDB boasts a proven track record in projects like OpenOffice. It allows straightforward database editing through an SQL browsing tool by accessing the file directly. H2, on the other hand, is reputed for its performance and is designed by the original creator of HSQLDB.

Derby and Berkeley DB

Derby offers strong performance but may require a more complex setup. Berkeley DB focuses primarily on key-value storage and is less suitable for SQL operations.

Recommendation

Based on your preference for Hibernate and the desire for SQL browsing capabilities, either HSQLDB or H2 would be appropriate options. HSQLDB provides stability and ease of editing, while H2 emphasizes performance. Ultimately, your decision depends on the desired balance between performance and stability for your specific application.
