Disclosed in the present application are a data access permission management method and apparatus, a terminal device and a storage medium. The data access permission management method comprises: acquiring report metadata from Tableau, the report metadata comprising a report ID; creating portfolio data in a Portal platform, the portfolio data comprising at least one portfolio, the portfolio comprising a portfolio ID; creating in the Portal platform an association relationship between the report ID and the portfolio ID; acquiring a user class permission configuration request inputted by a user, the user class permission configuration request comprising a user class ID and a target portfolio ID; and performing user class permission configuration in the Portal platform on the basis of the user class permission configuration request, to enable the user class corresponding to the user class ID to have the permission of accessing report metadata corresponding to the report ID corresponding to the target portfolio ID. The data access permission management method can grant the permission of each report metadata in a Tableau Server to a user class instead of a single user, so as to realize the flexible management of report access permission in the Tableau Server and improve the use range of Tableau.
