388 ;;Quote: a transaction-time database answers time-slice queries concerning the state of the database at a particular time
388+;;Quote: historical versions of a transaction-time database are never modified; store on WORM optical disk
390 ;;Quote: implement transaction-time database with commit-time timestamps and two-phase commit to agree on the transaction time; no extra message overhead
393 ;;Quote: use time-split B-tree (TSB-tree) for time-slice queries of a transaction-time database; data clustered by time-slice and key; replicate historical versions as needed; store on WORM disk
402 ;;Quote: time-split B-trees are space and time efficient; the fraction of redundant records is bounded
407 ;;Quote: time-split B-trees allow concurrent updates via short, independent atomic actions
408 ;;Quote: use a transaction-time database for backup by time-splitting modified nodes
