Integrated Approach to Conceptual Modeling

Conceptual modeling is supporting understanding and communication of the requirements in developing the information system (IS). The nature of requirements is usually divided into the functional (FRs) and non-functional requirements (NFRs). Thus, the scholars who are representing the conceptual modeling separate FRs and NFRs. Attempting to create an integrated framework for conceptual modeling of FRs and NFRs a new approach is being represented. In order to justify the approach, the research work and relevant literature in the field by using integrated perspective has been analyzed in this paper. As an outcome of this review, the need for an integrated approach to the requirement determination and proposed an integrated framework for conceptual modeling, which shall include the functional and non-functional requirements in one conceptual model has been identified. There is also identified that a small number of researchers have worked in this field, whilst the failure rate of the IS implementation which continues to be high has been the motivation, therefore the concept of proposing an integrated framework which will contribute to the increase of the efficacy of the requirements from the analysis phase in order to secure the sustainability of the IS has been approached.
