Business Objects and Components for Web-Based Information Systems Development
Abstract
Global competition among today’s enterprises forces their business processes to evolve constantly, leading to changes in corresponding Web-based information systems. Most existing approaches that extend the traditional software engineering to develop Web-based information systems are based on object-oriented methods. Such methods emphasize on modeling individual object behaviors instead of system behavior. This paper proposes the Business Process-Based Methodology (BPBM) for developing such systems by using a business process as a unified conceptual framework for analyzing relationships between a business process and associated business objects, for identifying business activities and designing object-oriented components called business components. These business components can represent more clearly semantic system behaviors than linkages of individual object behaviors. A change made to one business process impacts some encapsulated atomic components within the respective business component without affecting other parts of the system. A business component is divided into parts suitable for implementation of multi-tier Web-based information systems.
