Database Week06 47min ERD v 0.5 Logical Database Design and Data Dictionary

The SWE4304 Databases video series, developed for module leader Atheer Mahir, guides students from conceptual modeling to technical specification and practical database implementation. The first session covers advanced conceptual modeling using Enhanced Entity-Relationship techniques, including inheritance, specialization, and constraints. Using a real-estate case study, it teaches learners how to map entities accurately, validate schemas against business transactions, and avoid common structural design pitfalls. The main logical design lecture explains how to finalize schemas and build project data dictionaries. It focuses on validating Third Normal Form relations, defining entity, referential, and domain integrity rules, and preparing for physical implementation through candidate indexing and access control planning. A quick-summary video provides a rapid walkthrough of the final design phase, highlighting a three-point sanity check for keys and constraints while demonstrating how a central data dictionary prevents ambiguity during SQL table creation. The final session focuses on professional technical documentation. It demonstrates how to assemble a complete database engineering dossier, featuring version-controlled diagrams, dependency proofs, transaction coverage matrices, and architectural decision logs.
