15. 15 Architecture Tizen – Solutions Linux 2013
• Native and Web frameworks are complementary to each other
– Web is strong in portability, ease of app development, and has a minimal learning curve
– Native is relatively better in terms of performance and memory consumption
– Native enables reusing the existing engine and libraries written in C & C++ in app
development
Web vs. Native Framework

16. 16 Architecture Tizen – Solutions Linux 2013
• Different combinations for mixing Web and native, depending on
the characteristics or requirements of the app to be developed

17. 17 Architecture Tizen – Solutions Linux 2013
• Both are native in nature but focusing on different aspects
• Core focuses on:
– Providing common functionalities to Web and native frameworks
– No need to guarantee app binary compatibility (ABC)
– Performance and power optimization
• Native framework focuses on:
– Application development productivity while guaranteeing ABC
– Well-documented API references, developer guide, sample codes, and
associated tools
Native Framework vs. Core

18. 18 Architecture Tizen – Solutions Linux 2013
• Web and native applications
– Apps using only public APIs to get full
support for package installation and
upgrade, security, backward compatibility,
and so on
– Many sample apps included in the SDK
• Core applications
– Apps using Core APIs to fully utilize device
capabilities such as telephony
– Usually implemented and preloaded by
device implementers
– Backward binary compatibility is not
guaranteed
