Coarse-grained vs fine-grained

Coarse-grained: A few ojects hold a lot of related data. Example: A single "Account" object holds the customer name, address, account balance, opening date, last change date, etc. 

Fine-grained: More objects each holding less data. Example: An Account object holds balance, a Customer object holds name and address, a AccountOpenings object holds opening date, etc. There are relationships defined between these objects.
