Welcome to the JDBM project

JDBM is a transactional persistence engine for Java. It aims to be for Java what GDBM is for other languages (C/C++, Python, Perl, etc.): a fast, simple persistence engine. You can use it to store a mix of objects and BLOBs, and all updates are done in a transactionally safe manner. JDBM also provides scalable data structures, such as HTree and B+Tree, to support persistence of large object collections.

Download the latest version 1.0 (stable, released August 11th, 2005):

• Binary (jdbm-1.0.zip; 244k) includes Library, Javadoc and Examples
• Source (jdbm-1.0-src.zip; 885k) includes everything above, plus sources

Here is the current documentation:

• API docs

Here are two examples provided in the source distribution:

• FruitBasquet.java demonstrates the use of basic JDBM operations;
• FamousPeople.java shows how to use the B+Tree data structure.

Many commercial and open-source projects are using JDBM. See JDBM Powered for a list of who's using JDBM.
