SW Framework for enhancing the interoperability and reusability

SW Framework for enhancing the interoperability and reusability of e-Health Services April, 2012. National Information Society Agency, Korea e. Govframe Center Eunju Kim, Ph. D. outframe@nia. or. kr 1

E-Health Services implementation issues q How can we implement them efficiently and effectively. - Every e-Health service is not same but not so different - we can reuse the patterns and components of e-Health services among projects - reusability, interoperability and extensibility are needed Development Area E-Health Service A E-Health Service B E-Health Service C Unique Area Common Business Area in e-Health Common Technical Area OS OS OS HW HW HW 2

E-Health Services implementation issues q How can we assure the quality of the e-Health services? -Usually, e-Health Services perform very critical missions -Developing skills are not even among developers -Technical issues frequently causes lack of time for Package developing business issues Scree composit ion? on ling? co tion n Clien t? or k.

Software Framework q SW Frameworks are a special case of software libraries in that they are reusable abstractions of code wrapped in a well-defined API[Wikipedia] q Key features of SW frameworks 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. 4

Software Framework benefits In application development stage, 20 to 30% of development cost and effort can be saved by applying Software Framework. < IS* without SW framework > Service application < IS with SW framework > Service application Development area (100% done by developers) Middleware Operating system Hardware * IS : Information System 5

Software framework benefits q 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. < Separated development of applications> Error han < Integrated development of applications> t? men ut? yo P og sl Batch? es sin Bu ackage c a dling? ompositio nl e n? e r ? l c o n r S t n tio n co ra o i e t tions? p sac iness func O s u n B a o?

Software Framework Benefits q. 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 • Minimize incidents of error • Simplification and Standardization of development process • Secure performance and stability • Efficiency improvement through operation process standardization • System quality enhancement with the help of proven architecture • Time and cost reduction of system development 7

The needs for standardizing SW Framework SW framework became a basic tool for application development in Korea (71% of e-Government system from 2004 to 2007). 29% 71% § If an application is implemented on the basis of a vender’s SW framework, Biz logic becomes dependent on the SW framework. § Conventionally, SW framework is delivered as a black box § So only the framework provider can modify or maintain the application, bringing the dependency on the framework provider. 8
