1) Parse provides a backend as a service that allows developers to easily add features like push notifications, user authentication, file storage, and a database to mobile apps. 2) It offers an easy to use SDK for iOS and Android apps to connect to the Parse backend and manage data through a REST API or local SDK methods. 3) Parse's free tier supports basic usage, while paid plans provide more storage, requests, and features like scheduling and analytics for $199/month or less depending on usage.

- 3. Overview Easy backend building & nice web interface Push Analytics Social & authentification (Facebook connect, Twitter connect) Mail Hosting & Cloud code extension InApp Purchase Multi-plateforme SDK (iOS, OSX, Android, Unity…) REST
- 4. Backend 1/3 Powerful Data Management Data creation through Relational database or KVC
- 6. Backend 3/3 ACL (Classe level & Object level) Data type : String Number Boolean Array Object Date Bytes File Geoloc

- 11. Model 1/3 PFObject class Saving objects Saving Objects Offline
- 12. Model 2/3 Retrieving objects exemple Arrays
- 13. Model 3/3 Delete Counter PFUser or PFRole, PFProduct You manipulate object extending PFObject Relationnal Data one To Many (@"parent") Many to Many (PFRelation object)
- 14. Queries 1/2 Powerfull query system
- 15. Queries 2/2 queries with NSPredicates containsAllObjectsInArray/notContainedIn greatherThan/LessThan/lessThanOrEqualTo… relationnal queries limit x result or skip x result ordering on multiple keys compound Queries : orQueryWithSubqueries
- 16. Caching query.cachePolicy property 6 caches configuration, including: kPFCachePolicyCacheElseNetwork: The query first tries to load from the cache, but if that fails, it loads results from the network. If neither cache nor network succeed, there is a PFError. kPFCachePolicyCacheThenNetwork: The query first loads from the cache, then loads from the network. In this case, the callback will actually be called twice - first with the cached results, then with the network results. Since it returns two results at different times, this cache policy cannot be used synchronously with findObjects.
- 17. File PFFile class saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) progressBlock:^(int percentDone) getDataInBackgroundWithBlock:^(BOOL succeeded, NSError *error) progressBlock:^(int percentDone)

- 19. Social & sign-in Easy authentication with : Facebook based on FB SDK Twitter Login/pwd Helpers & feature on PFUser
- 20. User interface Parse provides a few subclasses of UIViewController that make logging in/ signing up PFUsers, and displaying PFObjects significantly easier.
