Personally, I love ZODB. I started up an ORM (object-relational  
mapping) tools developer for COM+ and .NET a couple of years ago, and  
ORM is the way to go when accessing an RDBMS. But, the ZODB has a  
more document oriented approach which is great for CMS, ERP etc.

In the applications I have developed for Zope 2, I use a combination  
of ZODB, RDBMS and the file system, depending on how the data is  
created, how it is used and the size of individual records. But I  
agree, if it is used as a holy grail of data storage (in the way some  
publishing systems tend to use RDBMS) it becomes a problem.

For me the ZODB has been a silver bullet because it is well  
integrated to Zope. I have even come to like aquisition... (with some  
reservations... ;) )
