This design assumes a centralised data platform ownership model where data is treated as a governed enterprise asset rather than a domain-specific by-product. It enforces controlled ingestion, unified metadata discipline, and structured consumption boundaries, with accountability anchored in platform governance rather than individual teams. Consumption is mediated through shared semantic services to prevent fragmentation and duplication. AWS provides the execution context, with governance anchored through AWS IAM Identity Center and AWS Glue Data Catalog to maintain identity discipline and metadata consistency.
