Hi Alexey Yes, that's right, I can not understand well the page 46. I suppose that R1 means "record version 1", R2 means "record version 2", etc.
Tx16 did the INSERT? Tx12 can do a COMMIT although it had started before Tx16 and Tx18 is still active? Tx25 can change what Tx14 did although Tx14 is still active? These things had confused me. Of course, I think that I am not understanding rightly the graph, that's why some words can help to do it clear. Greetings. Walter.
