The promise of relational database management systems of providing centralized data repositories customized to the organization’s data needs has not been realized, primarily because modeling the data requirements of a large number of users is prohibitively expensive. One potential solution is parallel data modeling of their own requirements by multiple end-users; however, teaching end-users to create their own normalized data schemas has so far been impractical. In this research in progress, we propose a methodology called the Data Screen Design (DSD) methodology that allows end-users to develop their own normalized data schemas by specifying data screens that support their business processes. We present the DSD model and the process used in the methodology. We also describe the usage of the DSD software tool that has been developed to support the methodology.
