BLOCKCHAIN FOR DATA AND MODEL GOVERNANCE

摘要

A model governance framework uses a shared ledger on the back of a blockchain. The solution tracks various analytic tracking documents (ATDs) and associated assets, like requirements and sprints, through various stages of an ATD lifecycle. Data schema and data distributions are also tracked. The decision models, corresponding variables and execution codes are also tracked. Existing variables and execution codes are made available via a preexisting asset ATD for reuse. Various transactions provide mechanism for accessing and manipulating the various assets through a recorded ledger of events and approvals. A system provides tracking of the approvals and the approvers of all model assets that are touched by any participant, and further provides access control and security for multi-user access. An application layer provides graphical access to the various aspects of the blockchain. Event notification provides the backbone for interfacing with various external systems like email servers and version control systems.
