It is a process that enhance the quality of data, so that it can be trusted better; it also sets principles about the dissemination of data, who can use it under what condition and  what information has to be provided when using it.....,

It is also to observe required principles like confidentiality and anonymity of particular data (e.g. research data), fulfilling right concerning the protection of privacy, etc. 

Data governance (DG) refers to the overall management of the availability, usability, integrity, and security of the data employed in an enterprise. A sound data governance program includes a governing body or council, a defined set of procedures, and a plan to execute those procedures.

The initial step in the implementation of a data governance program involves defining the owners or custodians of the data assets in the enterprise. A policy must be developed that specifies who is accountable for various portions or aspects of the data, including its accuracy, accessibility, consistency, completeness, and updating. Processes must be defined concerning how the data is to be stored, archived, backed up, and protected from mishaps, theft, or attack. A set of standards and procedures must be developed that defines how the data is to be used by authorized personnel. Finally, a set of controls and audit procedures must be put in place that ensures ongoing compliance with government regulations.

In other words: Data Governance is the practice of putting controls and best practices around an organization's data. Data Governance must be proactive and reactive.

The proactive Data Governance approach includes involving best practices applied to when new data elements are introduced, new projects that may affect data initiated, and projects are born out of the Data Governance office itself to pro-actively review data.

Reactive Data Governance comes into play when data problems are found, new laws and regulations are introduced or new initiatives are introduced in an organization.

thank u all for nice input

I strongly agree with all RG Colleagues.

Data Governance is the development, implementation and supervision of plans, policies, programs and practices that control, protect, deliver and enhance the value of data and information assets. There are several works that can be done and created through data governance, including:

Operation and management of electronic projects.

Providing and preparing scientific materials and research.

Language review of any content.

It was a pleasure to contribute to the debate of this topics.
