How to add a database backend
=============================

.. Assumption: A working Astro-Wise Environment


First make a checkout of the existing code inside an empty directory

.. code-block:: sh

   mkdir mybackend
   cd mybackend
   cvs -d cvs.astro-wise.org:/cvsroot co astrotarget


Use a different empty directory to test the new backend implementation as follows

.. code-block:: sh

   mkdir testbackend
   cd testbackend
   env AWEPIPE=<path_leading_to>/mybackend awe <testscript>


If needed, explicitly mention additional parameters from the command line

.. code-block:: sh

   env database_engine=sqlite database_name=sl3thing AWEPIPE=$HOME/mybackend awe sqlite_test.py
