A data mesh is a decentralized approach to data management that aims to democratize access to data across an organization. It moves away from a centralized model towards distributed data product teams that each own specific domains. Implementing a data mesh requires establishing technological, procedural, and political foundations like interoperability standards, shifting responsibilities away from central teams, and increasing data literacy. While a data mesh can provide benefits, it is a significant change that requires overcoming political and process challenges, and may not be a good fit for all organizations.
