Data-structure analysis
Abstract
Data-structure Analysis explores the relationships between different kinds of atoms. Deciding what relations to model is a second interactive fact-finding process. It explains a graphical approach to database design that starts with a schema derived by entity-relationship modelling or event-state analysis, then reduces all relations to functional dependencies. A functional dependency graph can then be drawn, which has a unique canonical reduced graph. The reduced graph reveals all that is necessary to design a relational database schema. A relational schema describes the database as a series of inter-related tables. A table is a conceptual structure, independent of its underlying implementation. Tables ...
