Deriving Object-Oriented Taxonomy from the Requirement Engineering Model for a Non-Fading Data Warehouse

Building a data warehouse (DWH) is a very challenging task. Most of the DWH projects fail to meet the business requirements and business goals because of the improper requirement engineering phase. The gap in between the development of requirements evolves due to disparity between the users and the developers, resulting in project devastation and terminations. DWH quality depends on the quality of its requirement engineering models. Agent orientation is emerging as a unique paradigm in requirement engineering for constructing DWH and maintaining the non-fading DWH property. Agent-oriented systems are expected to be more powerful, more flexible and more robust than conventional requirement elicitation models. The CAGDI stands for clustered agent-oriented decision information model, which has benefits over the agent goal decision information (AGDI) model and overcomes the short comings of the AGDI model. The model can be used in the early as well as in the late requirement elicitation. Object-oriented modelling is an important technique for database design because it organises system as a collection of interacting objects that combine data and behaviour. In this paper, the CAGDI model has been illustrated though the application of a banking system and at the end of the paper, the CAGDI model is given in the object-oriented paradigm in which the Unified Modelling Language UML diagrams, such as activity diagrams and sequential diagrams, have been discussed to prove the concept.
