1. SW Framework for enhancing the interoperability and reusability of e-Health Services May. 2011. National Information Society Agency, Korea eGovframe Center Eunju Kim, Ph.D. outframe@nia.or.kr

2. Software Framework • SW Frameworks are a special case of software libraries in that they are reusable abstractions of code wrapped in a well-defined API.[Wikipedia] • a special case of software libraries in that they are reusable abstractions of code wrapped in a well-defined application programming interface (API), • some key features that separate them from normal libraries • inversion of control: In a framework, unlike in libraries or normal applications, the program's flow of control is not dictated by the caller, but by the framework. • default behavior: A framework has a default behavior. This default behavior must actually be some useful behavior and not a series of no-ops. • extensibility: A framework can be extended by the user usually by selective overriding or specialized by user code providing specific functionality. • non-modifiable framework code : The framework code, in general, is not allowed to be modified. User can extend the framework, but not modify code.

3. Software Framework In application development stage, 20 to 30% of development cost and effort can be saved by applying Software Framework. Service application < IS* without SW framework > < IS with SW framework > Service application Development area (approx. 70~80%) Development area (100% done by developers) SW framework used (approx. 20 ~ 30%) Middleware Operating system Middleware Hardware Operating system Hardware * IS : Information System

4. Software framework • Software Framework provides an easy way to use development environment to developers, reliable runtime environment to the applications, stable operations environment to the operators Application development Application runtime Application operation Developer Operator Application Parameter Configuration Monitoring &control 1 3 4 Providing integrated development environment Providing runtime services Providing monitoring and management tools Development environment Runtime environment Operations environment 2 5 • Integrated development environment composed of commercial or open source development tools • Developers define runtime service by configuring parameters not by hard coding • Provides various technological common services such as transaction management, system log/error handling • Provides business common services • operations environment works in line with commercial SW such as Tivoli, Maxgent

5. Software Framework Benefits (1/2) • Reduction of TCO and enhancement of ROI can be achieved System development System operation • 20~30% productivity enhancement through the reuse of design and source codes • Simplification and Standardization of development process • System quality enhancement with the help of proven architecture • Time and cost reduction of system development • Minimize incidents of error • Efficiency improvement through operation process standardization • Secure performance and stability

6. Software framework benefits(2/2) • We can assure SW quality independent of the individual developer by asking them to focus on the biz logics while other technological issues are handled by SW framework. Error handling? Screen layout? Package composition? < Separated development of applications> < Integrated development of applications> Operation Transaction control? Business functions? Business requirement? Business functions? Interface with Tuxedo? Thin Client? Screen layout? Text transformation? Business improvement? System log? Framework A cache? Business requirement? Business log Batch? SW Framework Common biz service Common technological service Architecture policy

7.
