Abstract : |
Several processes have been advanced in the literature for reverse engineering of relational databases. The inputs to these processes are relational tables and available contextual information. The output is a model of the underlying logical intent, apart from the implementation artifacts. Most of the existing processes for database reverse engineering are inadequate; they assume too high a quality of input information. The authors of these processes are skilled database designers and they are overly optimistic about the state-of-the-art, as practiced. This paper catalogs odd aspects of relational database designs that we have encountered over the past several years. Many of these database designs are from commercial software products., |
