If in a database checkpoint log based recovery we know that if we see (<tn,start>,<tn,commit>) or (<tn ,commit>) we put it in redo list ?
But where to put the log if we see (<tn,start><tn,abort>) in redo list or undo list ?

what is the significance of checkpoint in a transaction ?
I am confused regrading the significance of checkpoint i.e. is it that whenever we place checkpoint does that mean that all the data items before it have been written onto the data base , if not then why do we place it below the transactions which have simply written the data item but not yet committed ?
