| Summary: | Decision makers use Data Warehouse (DW) for performing analysis on business information. DW development is a long term process with high risk of failure and it is difficult to estimate the future requirements for the decision-making. Further, the current DW design does not consider the early and late requirements analysis during its development, especially by using Unified Modeling Language (UML) approach. Due to this problem, it is crucial that current DW modeling approaches covered both early and late requirements analysis in the DW design. A case study was conducted on Malaysia Rural Health Care (MRH) to gather the requirements for DW design. The goal-oriented approach has been used to analyze the early requirements and later was mapped to UML approach to produce a new DW modeling called Goal-UML (G-UML). The proposed approach highlighted the mapping process of DW conceptual schema to a class diagram to produce a complete MRH-DW design. The correctness of the DW design was evaluated using expert reviews. The G-UML method can contribute to the development of DW and be a guideline to the DW developers to produce an improved DW design that meets all the user requirements |
