We present a model for component software. We describe how components are specified at the interface level, design level and how they are composed. From its external view, a component consists a set of interfaces, provided to or required from its environment. From its internal view, a component is an executable code that can be coupled with other components via its interfaces. The developer has to ensure that the specification of a component is met by its design and implementation. We also combine component-based and object-oriented techniques in component-based software development Keywords: Component, Contract, Interface, Object-Orientation, Refinement This report is a refined version of UNU-IIST Report 276 and is to be presented at and published in the proceedings IFIP WCC-TCS2004, 24-26 August 2004, Toulouse, France.
Charaterising Object-Based Frameworks in First-Order Predicate Logic
"... In the component-based approach Catalysis, a framework is a reusable artefact that can be adapted and composed into larger systems. The signed contract between components specifies how the required properties of one component are satisfied by the provided properties of another. We examine this conce ..."

In the component-based approach Catalysis, a framework is a reusable artefact that can be adapted and composed into larger systems. The signed contract between components specifies how the required properties of one component are satisfied by the provided properties of another. We examine this concept in the context of framework-based development. Although Catalysis advocates rigorous development, frameworks lack a comprehensive formal foundation. We consider a simplified view of frameworks and their transformation into first-order logic. Theorem proving may be used to check the consistency of framework specifications and we identify ways in which these specifications may be simplified beforehand

Republic of China and Portugal through a contribution to the UNU Endownment Fund. As well as providing twothirds of the endownment fund, the Macau authorities also supply UNU-IIST with its office premises and furniture and subsidise fellow accommodation. The mission of UNU-IIST is to assist developing countries in the application and development of software technology. UNU-IIST contributes through its programmatic activities: 1. Advanced development projects, in which software techniques supported by tools are applied, 2. Research projects, in which new techniques for software development are investigated, 3. Curriculum development projects, in which courses of software technology for universities in developing countries are developed, 4. University development projects, which complement the curriculum development projects by aiming to strengthen all aspects of computer science teaching in universities in developing countries, 5. Schools and Courses, which typically teach advanced software development techniques, 6. Events, in which conferences and workshops are organised or supported by UNU-IIST, and 7. Dissemination, in which UNU-IIST regularly distributes to developing countries information on international progress of software technology.
