Development Approach
To give the application features and functionalities that would make it’s operation smooth, the following development approach was used.

  • High level of data fetching technology from server was introduced

  • For data synchronization with the server and data backups, high level coding standards were used to maintain the most recent updates with the server.

IOS Architecture
Core OS and Core Services layer: this layer in the iOS architecture contains fundamental interfaces for access to low level data types, files and netword interfaces and sockets. Core Foundation, CF Network, SQLite and access to POSIX threads and UNIX sockets are the major technologies amongst others.
