Taleo TEE Termination Extract - has anyone worked with one?

Content

My company has recently finished up using Taleo and we've requested a termination extract. It has been loaded into a local oracle database and presents as a large amount of database tables with no relationships defined between them.

I'm required to extract all the requisition data for job applications from the databases and I'm having issues pulling out the respective data. Since there are no defined relationships I'm having to manually rebuild all the links between each table to see what data can be extracted.

Has anyone worked with a TEE extract before? Or knows of any documentation that may help such as data dictionaries or SQLs?
