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.

this package contains the apache fork of jdbm used by apache directory server.
