mparchet, Let Core Data do the heavy lifting for you, that is what it is there for. If you use an array controller with your UI and set up bindings you can get away with out writing any code to make the base of your UI work. If I remember correctly you can send your own SQL queries but you can do _almost_ anything you need to do easier through Core Data so you should really question anytime you start to make your own queries. If you need some guidance on using Core Data with a financial related app check out my blog @ http:www.theMikeSwan/blog, I wrote a sample app for tracking expenses that may be of assistance to you.
As for fetch requests, they are really useful for doing searches of the data. Above all keep in mind that Core Data is NOT a database, it is a persistence framework. If you think of it as a database you will just make your life harder.
