NoSQL: a non-SQL RDBMS

Perl and the Operator/Stream ParadigmNoSQL uses the so-called Operator-stream Paradigm?. The main reason why I decided to turn the original RDB system into NoSQL is precisely that the former is entirely written in Perl. Perl is a good programming language for writing self-contained programs, but its pre-compilation phase and long start-up time are worth paying only if once the program has loaded it can do everything in one go. This contrasts sharply with the Operator-stream Paradigm, where operators are chained together in pipelines of two, three or more programs. The overhead associated with initializing Perl at every stage of the pipeline makes pipelining Perl inefficient. A better way of manipulating structured ASCII files is to use the AWK programming language, which is much smaller than Perl, is more specialized for this task, and is very fast at startup.
