Query Builder/Database Type Joins

Hi all,

I am currently trying to create a Query Builder report that retrieves information on an EPM Document and the Life Cycle Template the EPM Document is using.

I am familiar with the use of Joins to capture the relationship between the types, however, I am unsure how to create the join for these two types.

To explain further, I already use a join to link between EPM Documents and WTParts:

Similarly, I use EPMDescribe Link to create a join between EPM Document Master and the related drawing.

Can anyone help me identify the link between EPM Document and Life Cycle Template?

If there is a way of figuring out any of these links (perhaps by viewing the database structure) this would also be a great help.

Thanks for your time,

Tris
