Immutability

Immutability is also a big buzzword in these days along with all the functional buzz - guess they are sort of related. As stated earlier I'm not opposed to functional and other approaches, I'm just wary that all the paradigms are not solving anything - I mean they are mostly trying to keep data consistent and thus not deal with inconsistencies, but my point is that there will always be an outside, a side effected world where inconsistencies cannot be avoided.
Therefore I'm (with Dawn) investigating patterns to deal with inconsistency, instead of trying to design my way around it.
Needless to say that parts of the world WILL have to be transacted and consistent, but a general pattern that can deal with inconsistency can also deal with consistency.
