The comparison was vs keeping stuff in a hash table in memory, and I was saying databases are no worse.

But that's clearly not true. In the most extreme case, that hash table is referenced simply by a variable in your program - it's already in your program's address-space! There's no way a database can come close to that.

Not to mention that you can hash arbitrary objects in a hash table with no mapping of any kind.

    hash at: key put: anObject
Databases are vastly more complicated and require me to completely disassembly the object graph anObject may contain into a set of tables and rows to store it, and then reassemble the graph from tables and rows back into their object form when fetching.

The second one commits to using a relational database, one often easily triples the size of the code base. There's nothing simple about that.
