Data Modelling & Design: understand the concepts and exam cues.
Representing data structures precisely to capture business meaning.
Data Modelling & Design is the discipline of discovering, analysing and representing data requirements in a precise form called a data model. It moves from conceptual (business subject areas) through logical (platform-neutral structures) to physical (implementation), and it is the most notation-heavy chapter in the exam — normalisation, keys, cardinality and modelling styles are all tested with precision.
Inside the companion: this chapter includes an overview, learning objectives, topic priorities, core concepts, exam cues and revision material. Some chapters also include dedicated diagrams and relationship maps.
