RDB2 Model: A Relational Databases Retro-Design Tool Enriched by the Extraction of Constraints

摘要

In this paper, we present a method that retro-designs a relational database to generate a conceptual model by extracting data structures and constraints: Our method extracts a conceptual model directly from an existing relational database without using the ER model (Entity / Relationship). The method is proposed as a two-step process, the first is to extract the data structure of the relational database and the conceptualization of this data structure by generating a conceptual model. The second stage involves the extraction of relational constraints and the semantic enrichment of the conceptual model by improving the understanding of relationships between data structures.
