Rim has stopped using the terms `relation', `attribute', and `tuple'
and now uses only `table', `column', and `row' for all user
messages and documentation. However, most of Rim's subroutines
still use the old terms. You should consider the sets of
terms to be synonymous.
The term `page' is used to mean a fixed-length portion of a file.
All I/O is performed at the page level. The term `record' means
a logical set of data. Generally a page will contain several
records.
