Subtopic: write-once file system up

Quote: file system for a WORM disk and a disk cache; read-only snapshots at any time by flushing the cache (a few seconds); assumes unbounded capacity [»quinS12_1991]

Subtopic: CDROM up

Quote: a CD-ROM holds about 12 billion bytes per pound [»millDC_1986]

Subtopic: data compression up

Quote: use Huffman codes to compress text for CDROM and limit access; encoding appears random [»kleiST7_1989]
Quote: use decoding tables to process Huffman codes; use CDROM's robust, physical encoding to ignore their sensitivity to errors [»kleiST7_1989]

Subtopic: time-split B-tree up

Quote: historical versions of a transaction-time database are never modified; store on WORM optical disk
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 [»lomeD_1993]
Quote: if insert into an index without rewriting can write during reads and can use optical disks [»faloC9_1988]

Subtopic: append-only up

Quote: Google's scalable distributed file system was designed for frequent component failure and huge, append-only files
