Greenspuns Tenth Rule Of Programming and ADO.NET Data Services

This is a humorous observation once made by Philip Greenspun:


Any sufficiently complicated C or Fortran program contains an ad-hoc, informally-specified, bug-ridden, slow implementation of half of CommonLisp.

Or the database variant (Greencodds Tenth Rule Of Programming):

Every sufficiently complex application/language/tool will either have to use a database or reinvent one the hard way

I sometimes I feel that:

Any sufficiently complicated procedural api contains an ad-hoc, informally-specified, bug-ridden, slow implementation of half of query language.

Take for example, Web Services, they started a procedural thing where people created their own custom verbs for each service, then people realized that the semantics of HTTP constitutes a coordination language which is is sufficiently for any computational communication pattern, they realized that GET / PUT / POST / were enough for any program, but they again forgot about the query part, so after a while they reinvented a query language (like SQL) by creating create a query language based on URL query strings, as in ADO.NET Data Services)

Sometimes I feel all IT industry is like a dog chasing its own tail… we invent Cobol to handle data procedurally only to invent SQL to handle data declaratively only to invent stored procedures and web services to handle it procedurally to then invent REST to handle it declaratively I wonder what will be the name of the procedural silver bullet that will replace REST…
