The information construction of many vocational colleges has accumulated a certain amount and different forms of data, which are in the form of relational data based on traditional business systems, log files of network devices and software, and external data related to vocational colleges. These data cannot be integrated, correlated, managed and analyzed through traditional business systems. It is necessary to use big data technology to govern these different types and sources of data, and on the basis of data governance, data integration, analysis and prediction are carried out to provide digital support for scientific management and decision-making of vocational colleges. In the field of data governance, what distinguishes vocational colleges from undergraduate institutions is not only the difference of data scope, but also the general lack of awareness, methods and talents of data governance in vocational colleges. This paper focuses on the awareness cultivation of data governance, data governance methods and data governance team building, and tries to study the methods and procedures from data governance strategic planning, data analysis procedure, data governance procedure, making data governance policy and establishing data governance structure, data management and data governance team formation.
