Solutions to empower and (re-)engage vulnerable and marginalised populations to unfold their hidden potential allowing them to fully participate the social, economic, cultural and political life, necessarily involve institutional change. This in turn necessitates understanding the processes and mechanisms by which social innovations lead to in-stitutional change. Considering the specific nature of social innova-tions as interactive, generative and contextualised phenomena while maintaining that many practices at the micro-level can add up to patterns and regularities at the macro-level, middle-range theorising (MRT) is proposed as an appropriate method to theoreti-cally underpin and substantiate theoretical advancements towards a multidisciplinary perspective on the economic dimensions of social innovation, identifying the direction of future empirical inquiries.
An EJB container can host three types of beans: Session beans to model business processes, entity beans to represent business objects and message-driven beans to provide for asynchronous method calls. This paper addresses entity beans and their mapping to persistent storage, especially relational and object-relational databases. A tool named BeanMaker is presented which can do object mapping either automatically by metadata analysis of a database schema or manually based on intrinsic real world semantics supplied by the user. BeanMaker is a running prototype system with an intuitive GUI interface. This paper looks what's behind the scenes and focuses on design issues and concepts of code generation.
