I admit I didn't look at Magma yet.

My comment was directed to relational database vendors, who control our 
database mentality and perceptions, and consequently a fear against 
databases like Magma (and Gemstone etc) too. But definitively against 
image as a database.

Why I like a concept of image as a database? Because it simply works, 
and that is my concrete experience. Also a fear of losing data is mostly 
baseless - a chance of losing data is very small, again from experience. 
So small that it is close to a chance of loosing of data on relational 
databases, I would say. That is a strong wording I know, but let we at 
least start thinking about this probability.
