Hi there Matthew, Yes you are correct the UUIDs that CF generates are totally unique and therefore you should not have a problem.
There is however a theoretical limit here. As it is a finite length string, please do not go wasting UUIDs, we will run out shortly if you do that :) Thanks, Lucas. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: 12 July 2004 7:56 AM To: FarCry Developers Subject: [farcry-dev] Spectra Objects into FarCry Hello, I am looking to use FarCry as a replacement for a Spectra system. As such I have started developing the idea (and some CFML) to transfer the necessary Object data from the Spectra database structure to the FarCry database structure. After some small investigation, it seems that both systems (Spectra and FarCry) are using Universally Unique Identifiers (UUID) as ObjectID. These UUID ObjectIDs then appear to be assumed and used as unique identifiers and keys where necessary in the system. Further: the definition of a Universally Unique Identifier generally mentions that it is 'an identifier standard used in software construction, standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE)' and the ColdFusion documentation says that 'The ColdFusion UUID generation algorithm uses the unique time-of-day value, the IEEE 802 Host ID, and a cryptographically strong random number generator to generate UUIDs that conform to the principles laid out'. Based upon this I am working on the premise that UUID are fairly well just what they say they are, that is 'Universally Unique' and from one system to the next they still remain unique. Further as the ColdFusion UUID generation algorithm uses a Host ID, and in my case I have the Spectra system installed and running on one host and FarCry system installed and running on another different, unique and new host, I am feeling fairly confident that the uniqueness is guaranteed (leave alone the other parts contributing to the number generation process). This all being so, it should be quite satisfactory to import the Objects from my old Spectra system directly into the FarCry system using their existing ObjectIDs. Would anyone care to offer any constructive comment on why this might NOT be a good strategy to implement?
