Welcome to the JDBM project

MOVING!!!!

JDBM's development has moved to Github. Jan Kotek is working on a neat set of features under the name "JDBM3". If you want to pull the latest and greatest source code, or want to help him out, check here. This SourceForge project will stay as long as SourceForge allows for archival purposes.

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.
