→The Core Data Stack
== The Core Data Stack ==
<google>ADSDAQBOX_FLOW</google>
Core Data consists of a number of framework objects that integrate to provide the data storage functionality. This stack can be visually represented as illustrated in Figure 43 -1.
As we can see from Figure 43-1, the iOS based application sits on top of the stack and interacts with the managed data objects handled by the managed object context. Of particular significance in this diagram is the fact that although the lower levels in the stack perform a considerable amount of the work involved in providing Core Data functionality, the application code does not interact with them directly.
