Create database model for iOS application

We need to have a data model and core data database created for a new iPhone application. The application will have its graphical design created by Elviranett. The job is to create a nested data model with core data with table views. The model must also be able to sync data to iCloud. Short description of how the user will use the application: 1. The user create a party 2. The user add following elements to a party: -location -occasion -notes -purchases -tasks Some of the elements must be possible to reuse for other parties. Deleting a party should not delete these elements from storage: -location -purchases -tasks Example: USER create Party A with Location B and Purchases D. (Location, purchases and tasks are created in this party creation) USER delete Party A. USER create Party B USER choose Location B and Purchases D for the new party from a list that is stored. Attached is our description of the element. We will send you a exmaple of views for more accurate pricing.
