Data Integration & Interoperability: understand the concepts and exam cues.
Moving and consolidating data reliably between systems and formats.
Data Integration & Interoperability (DII) covers the movement and consolidation of data within and between data stores, applications and organisations. It spans ETL/ELT, replication, messaging, APIs and the patterns that let heterogeneous systems exchange data reliably. Integration points are also where data quality most often degrades.
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.
