A cloud based service architecture is used in providing Master Data Management (MDM) services to clients. The MDM cloud based architecture comprises a client architecture and a server architecture. The client architecture includes synchronization services that are used to interact with the MDM cloud based service. The server architecture comprises a public Application Programming Interface (API) and a portal for accessing different MDM functionality. For example, a client may access the server architecture to create/modify MDM workflows that are hosted by the cloud based service. The cloud based service architecture also provides access to different MDM services including MDM workflows, validation, transformation, and storage relating to master data. The cloud based architecture may be used to publish master data and/or subscribe to master data.
