There are a +number of "operators" that each perform a unique function on the data. +The "stream" is suplied by the UNIX Input/Output redirection mechanism. +Therefore each operator processes some data and then passes it along to +the next operator via the UNIX pipe function. This is very efficient as +UNIX pipes are implemented in memory (at least in versions of UNIX at +RAND). RDB is compliant with the "Relational Model". + The data is contained in regular UNIX ACSII files, and so can be +manipulated by regular UNIX utilities, e.g. ls, wc, mv, cp, cat, more, +less, editors like the RAND editor 'e', head, RCS, etc. |
