I want to write an application which stores records in a simple database. I have used "B-tree helper" in the past (for Mac OS). I want to store records in multiple B-trees. I have some really basic queries.

I notice that the c compiler for MacOS X allows storage of records in a simple B-tree. I was thinking that multiple b-trees could be used by creating a file wrapper, and then making multiple file to go in the file wrapper(each file is one b-tree?). Does this sound feasible/desirable?

I understand that Enterprise Object Frameworks is an object framework for database management, but that a "backend" database is required. Can the b-tree utilities in the native C-compiler form that backend?

Is EOF framework packaged with Cocoa?

Is there any other solutions to a basic database storage/retrieval in OS X?

Any comments appreciated.

Peter,

EOF is not packaged with the Cocoa development tools - in fact it's not yet released for MacOS X. You do get EOF with WebObjects but that currently only works on OSX server, Windows NT and Solaris?

EOF works using a "database adaptor" to the back end database so that your business logic code is independent of the database. In principal you could write an adaptor to interface with your simple b-tree storage system. This would then let you plug in a more powerful database back end as the requirments for the system grow. However if you're just writing an address bok app this may be overkill :-)
