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.

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

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 Providing integrated development environment Providing runtime services 4 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

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

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. < Separated development of applications> < Integrated development of applications> Business requirement?

What are the differences before and now? Redundant development of similar functionalities in every projects Vender Dependency due to framework delivered as black box Disadvantage to SMEs who cannot afford to possess the framework Difficult to maintain the system due to lacking on development standard Spent longer time and labor to link the systems due to different framework Now Reduction of redundant development by reusing 219 common components Eliminating dependency to the provider by utilizing open sources framework Enhancement of SMEs competitiveness through sharing standardised framework Convenient to maintain the system with help of proven development standard Enhances interoperability between systems by standardised framework
