I am a little less biased ;-)

I think Manuel's Metabase is the bomb.  Unfortunatly, so does Windows...

Metabase provides some truely wonderful features.  On Windows, Metabase with
OCI8 my server keep performing illegeal instructions.  I think this is a
lack of PHP's maturity on Win32,  not Metabase's fault.

On linux, web pages work wonderfuly with Metabase.  Needing to support a
Windows Server, so I'm working on going back and yanking out Metabase.  This
is where I am learning that Metabase really is nice.  OCI* functions by
themself are not nearly as convenient as Metabase functions.  I expect this
is true of most databases and PHP.

Kudos Manuel!

There is a bit of a learning curve with Metabase, but the curve exists for
all the independent database functions as well.  Tempted to use PEAR
implementation, but fear it Would suffer the same dilemma as Metabase on
Windows and it's not nearly as mature as Metabase.
