Data extraction blackboard learn

I need to replicate functionality of an already existing script which extracts information from a Moodle-database. The scripts needs to extract the "same" information from a Blackboard learn 9.1 install. Data that needs to be extracted is: Discussion group activity Access logs Gradebook-data Data from quizzes and assignments Names and emails (if available) of students in the courses. All this aggregated by course and user, in nice separate folders and in csv format for zipping and processing in a different application. Knowledge of Bb data-model is a must, and access to live or back-up database necessary to complete the project.
