A logical design methodology for relational databases using the MAO (Multiple Aspects-based Object) model

In this paper, the authors present a stepwise design methodology for relational databases using a new conceptual data model, the MAO (Multiple Aspects-based Object) model. The present methodology consists of two steps: first, data requirements are conceptualized using the MAO model with concepts such as object types and aspect types; second, the MAO model is transformed into the third normal form in the relational model supported by commercial DBMSs. A top-down approach is used for the MAO modelling in the first step, and the transformation process in the second step can be automated. The present methodology supports easier and more accurate database design of real world than other methodologies using existing data models. [In Korean.]
