We recently programmed a CakePHP app which relies solely on remote server talking Saleforce API for all data operations. The first challenge that we faced was how to prevent CakePHP from insisting on a database connection. The solution was simple enough and I never gave it much thought till the same question was brought up by more than one person on the CakePHP list. The solution involves creating a minimal dbo source file.

It's a simple three step process to follow - making the dbo source file, set it up as the default driver and tell CakePHP to $useTable = false.
