Membership paid date, quick easy question

I have a quick question for a savvy developer....

I need to show the "Paid on Date" using my own custom display. After having looked through the dbase, I assume I need the date from the following table and column?

wp_m_membership_relationships
startdate

Would this info be stored anywhere else or is this the only place I need to grab the data in order to show.... "The New Member paid on date xx/xx/xxxx"

Thanks in advance....
