2010. The graphics for those three rows extend through Decem-
ber 2010 because, with this temporal transaction complete, the
results are guaranteed to remain in the table, unaltered in any
way, until the next clock tick. And as we said before, throughout
this topic we are using a clock that ticks once a month. The
graphic for row 6 only extends up to December 2010 because
the delete transaction sets the effective end date for that version
(and thus for the entire episode) to December 2010.
Glossary References
Glossary entries whose definitions form strong inter-
dependencies are grouped together in the following list. The
same glossary entries may be grouped together in different ways
at the end of different chapters, each grouping reflecting the
semantic perspective of each chapter. There will usually be sev-
eral other, and often many other, glossary entries that are not
included in the list, and we recommend that the Glossary be
consulted whenever an unfamiliar term is encountered.
