[ 1/2 OT ;-) ] This sounds very functional to me...

[Oliver Bandel]

Hello,


  "PostgreSQL creates a new version of the row and also retains the
   old or expired version. Database systems that use row-level
   locking do not retain old versions of the data, hence the need
   for locks to maintain data consistency."

this sounds very functional to me,
like non-destructive updates/functional datastructures...

... does FP ideas become more and more popular?

The quote is from:

OK, it's not absolutely new, but it's > y2k. ;-)

I also heard of gcc that newer versions use FP-like ideas....


Ciao,
   Oliver

Yes. The LINQ project brings functional programming to databases. Both Java 
and C# are adopting functional features (like closures).

Quite a few database people (often those with a background in
accounting) tell you that you should never overwrite any data.  Early
versions of PostgreSQL followed that closely, so you could not delete
any data and free up the space (but you were able to time-travel to
older table versions).

The functional revolution is underway, people just don't realize it yet. 
My favorite example is Java's revolutionary "Spring" framework, which uses
"inversion of control" -- basically just a weak, limited version of
function passing.  Sooner or later business will start to realize they
need to move beyond Java/C#: it's just going to take some nudging along.

Isn't it just so typically there begins to be support for it,
at a time theorists are moving to understand stateful systems.
