What is the definition of Full Data and Ordered Data?

Hi,

I understand what Ext3 file system is and the concept of journaling, but I have not been able to find the specific definition for these 2 advance features talked about: Full data journaling and Ordered Data journaling.

Are these just part of Ext journaling, like they are just features and not some different journaling methods? What do they mean?

cheers!

A google search turned up this explanation. Sounds like a full data journal writes a complete copy of the data to the journal; ordered data doesn't store a full copy, but records transaction information and other metadata.
