&gt; :The two things I'm pondering now are binary flat files (one per object,
&gt; :a collection of objects?? I dunno) or a database.
&gt; 
&gt; A binary form has the distinct advantage that it is relatively easy to
&gt; replace a single entity in the file. With text files, variations in
&gt; formatting of things like numbers make that harder. If you need to save
&gt; more than one kind of thing in your file (fairly likely!), then you can:
&gt; 
&gt;     - have multiple files, one per type of entity
&gt; 	[can be expensive in terms of file handles and space]
&gt;     - reserve portions of the file for arrays of the different entities
&gt; 	[what happens if you overflow a portion, needing more space?]
&gt;     - set up means by which varying lengths and types of things can be
&gt; 	interspersed in the file, and properly found and updated.
&gt; 	[can get complicated]
&gt; 
&gt; The third choice is pretty close to writing your own DB system.

Any hints and tips on this third choice? References? Web sites? (Good) Books?
