Abstract
Conceptual and logical database design are complex tasks for non-expert designers. The popular data models for conceptual and logical database design are the entity-relationship and the relational model, respectively. Logical design methodologies for relational databases have relied on mathematically rigorous approaches which are impractical, or textbook approaches which do not provide the rich constructs to capture real applications. Designers have to use intuition to develop rules and heuristics. Proposes a realistic and detailed approach for conceptual design using the ER model for relational databases, based on 3 rules that specify the order in which various types of relationships must be modelled, 3 rules that pertain to detection of derived relationships, and 3 heuristics based on observation of constructs in real applications. The approach is illustrated by many examples
