Berkeley DB / Berkeley DB XML binding for Haskell Version 0.2 23 Sep 2008 by Stephen Blackheath

Berkeley DB XML is a powerful, fully transactional, XML-based database that uses XQuery as its query language. You can download it here:

http://www.oracle.com/database/berkeley-db/xml/index.html

This package provides a Haskell binding for Berkeley DB XML. It is a tolerable subset of the API, and I hope to improve it over time. I have stuck closely to the C++ API, with some minor changes where a Haskell idiom seemed appropriate. I hope that people will develop higher level wrappers for it. I have had great success with the "pickler" interfaces in the HXT library. In a future version of this package I will give some examples.

This package is in its very early stages, and needs some work, but it should allow you to write a fairly serious application. If you find some part of the API that is missing, and would like it added, please contact me.

I hope this package helps make Haskell better. I am partly motivated by a belief that SQL is holding us back. An advanced language should have an advanced database.

If you just want Berkeley DB without Berkeley DB XML, you should be able to achieve this easily by modifying the BerkeleyDBXML.cabal file. The Berkeley DB parts do not depend on the Berkeley DB XML parts. Some time I will make this easier.

To install, use the standard Cabal install procedure:

runhaskell Setup.hs configure runhaskell Setup.hs build sudo runhaskell Setup.hs install

If Berkeley DB or DB XML is not installed in the default location of /usr or /usr/local, you will need to specify the paths in this way:

runhaskell Setup.hs configure
--extra-include-dirs=/usr/local/dbxml-2.4.13/include/dbxml/
--extra-lib-dirs=/usr/local/dbxml-2.4.13/lib/

Cabal does not seem to check these very well. If you get the lib directory wrong, you won't find out until you try to build the examples.

See the examples/ directory.
