The article discusses a new method called Business Process-Based Methodology (BPBM) for developing Web-based application systems. This method focuses on using business processes to analyze relationships between business activities and objects, leading to the creation of business components. These components are designed to be reusable and represent system behaviors more clearly than traditional methods. Changes made to one business process only affect specific parts of the system, making it easier to manage and update. This approach aims to improve the development of multitier Web-based applications.
