• '''Fetched property''' – This provides an alternative to defining relationships. Fetched properties allow properties of one data object to be accessed from another data object as though a relationship had been defined between those entities. Fetched properties lack the flexibility of relationships and are referred to by Apple’s Core Data documentation as “weak, one way relationships” best suited to “loosely coupled relationships”.
• '''Fetch request''' – A predefined query that can be referenced to retrieve data objects based on defined predicates. For example, a fetch request can be configured into an entity to retrieve all contact objects where the name field matches “John Smith”.
