Model Once, Represent Everywhere: UDA (Unified Data Architecture) at Netflix

The blog post introduces Netflix's Unified Data Architecture (UDA), which aims to unify the representation of data models across various systems, enhancing automation, data discoverability, and semantic interoperability. UDA resolves issues like inconsistent terminology and duplicated models by allowing teams to create a common model for business concepts, which can then be used consistently across different platforms. The post also discusses challenges faced in operationalizing UDA and highlights real-world applications such as Primary Data Management (PDM) and Sphere, improving business users' access to operational reporting and data integration.
