Development Task Flow for iOS Applications Using OData SDK (Messaging Channel)

Describes the overall development task flow for ODP applications using messaging channel. An application consists of building blocks which the developer uses to start the application and perform functions needed for the application.

1. Initializing the Application
   Initialize the application when it starts the first time.
2. Setting Server Details
   Set or update the connection properties of the server before or after user registration.
3. Enabling Single and Mutual SSL Authentication
   Secure sockets layer (SSL) is a protocol that governs certificate authentication. It exchanges the certificate information. SSL also encrypts all information that flows between a client and a server.
4. Registering a User
   Using a predefined authentication mechanism, register a user automatically. You can register the user either synchronously or asynchronously.
5. Sending Data Request to the Back-end
   You can forward data request messages to the back-end through the SAP Mobile Platform server synchronously or asynchronously.
6. Retrieving the Response from the Back-end
   Based on the data request sent to the back-end, you need to retrieve the data as a response to the device.
7. Using HTTPS over the SAP Mobile PlatformMessaging Channel
   (Optional) Clients can securely communicate with the backend via the server through the HTTPS transport protocol. By using SSL over the SAP Mobile Platform Messaging Channel, all messages are encrypted and authenticated to ensure secure communication.
8. Debugging Runtime Error and Performance Analysis
   To handle occurrences of exceptions and special conditions that change the normal flow of the program execution, error handling has to be done appropriately.
