// | |
// | |
// | |
// feedback_template feedback_completed
// (CL,pk->id) (UL, pk->id, fk->feedback)

// feedback_item---------------------------------feedback_value
// (ML,pk->id, fk->feedback, fk->template) (UL, pk->id, fk->item, fk->completed)
//
// Meaning: pk->primary key field of the table
// fk->foreign key to link with parent
// CL->course level info
// ML->modul level info
// UL->userid level info
// message->text of each feedback_posting
