A method, performed by a first node (111), for managing data in a database (115) in a communications network (100) is described. The first node (111) operates in the communications network (100). The first node (111) receives (302) a request from a second node (112) operating in the communications network (100). The request is to modify an authorization to manage the data. The request is received as a service operation of a set of service operations provided by a service of the database (115). The first node (111) provides (303) a response to the second node (112) based on the received request, and further based on the authorization as defined by a third node (113) operating in the communications network (100). The first node (111) is a service producer of the database (115), the second node (112) is a service consumer, and the third node (113) is an initial provisioner of the authorization.
