MDA represents a fundamental standard established by the Object Management Group (OMG) that serves as a foundation for model-driven development. Within the MDA framework, the computation-independent model (CIM) holds the position of the initial abstraction level. As a business model, the CIM describes the requirements and environment of a business, playing a pivotal role in influencing all other levels of the MDA approach. Recognizing the significance of this stage in MDA, the primary objective of this paper is to propose a web-based approach for automating the construction of CIM. This approach utilizes web interfaces to gather relevant information from users about the business model. Furthermore, an illustrative example is presented to provide a clearer demonstration of the application of this approach.
