The supported sort selectors for SQLite are compare: and caseInsensitiveCompare:, localizedCompare:, localizedCaseInsensitiveCompare:, and localizedStandardCompare. This is done primarily for performance, but it means that evaluation happens in a non-Cocoa environment, and so sort descriptors (or predicates) that rely on Cocoa cannot work. The SQLite store, on the other hand, compiles the predicate and sort descriptors to SQL and evaluates the result in the database itself. In the XML, binary, and in-memory stores, evaluation of the predicate and sort descriptors is performed in Objective-C with access to all Cocoa functionality, including the comparison methods on NSString. To ensure data security, use a technology such as an encrypted disk image.ДЇetching differs somewhat according to the type of store.

Note also that it is possible for data archived in the metadata to be tampered with independently of the store data. The SQLite store offers slightly better security than the XML and binary stores, but it should not be considered inherently secure. You might use the binary store if you want store writes to be atomic.Д¬ore Data makes no guarantees regarding the security of persistent stores from untrusted sources (as opposed to stores generated internally) and cannot detect whether files have been maliciously modified. In a deployed application that uses a large data set, you typically use an SQLite store because it offers high performance and does not require that the entire object graph reside in memory. It is common, for example, to use the XML store early in a project life cycle, because it is fairly human-readable and you can inspect a file to determine whether or not it contains the data you expect.

Given the abstraction that Core Data offers, there is typically no need to use the same store throughout the development process. If you have an existing SQLite database, you need to import it into a Core Data store. You cannot create a SQLite database using the native SQLite API and use it directly with Core Data, nor should you manipulate an existing Core Data SQLite store using native SQLite API. Although Core Data supports SQLite as a store type, the store format-like those of the other native Core Data stores-is private.
