I realize this post is quite old without any answers (moving it to the BSA area)
But, you could pick the BL2ATRIUM installer applicable to your BSA version and run the installer with the "utilities only" option. This will simply extract the install files in to the directory of your choice. In the install folder you will then have the SQL scripts to create the tables, views etc that AIE uses to pull the data from BSARA db. These tables and views are pretty much self explaining when you look at them I you should be able to use these in your AI jobs.
This is not a tested setup. Your best option ofcourse would be to upgrade your BSA environment to a version where the installer is supported.
