The Data Governance layer

The Data Governance layer in a Data Fabric architecture represents different architectural patterns brought together to ultimately create a fabric of connected metadata and data. There are two key components in the design of the Data Governance layer – active metadata and life cycle governance. Each of these components at a physical level can be made up of several microservices that communicate with one another by leveraging different styles of communication such as APIs and event-based communication. The key architectural pattern in the Data Governance layer relies on metadata. From an implementation perspective, several technologies and tools are involved in this space, such as a data catalog, which leverages a streaming platform to communicate metadata updates. Leveraging an event-based tool for metadata updates ensures the latest most up-to-date metadata is collected.
