A database management system and a method of managing a database storing a plurality of entities related to each other by a plurality of relations. The database management system includes a user interface for interfacing with the database in a current situation. The system also includes a context modeler for modeling a context representation and a server for storing a situation in which the user has been involved as at least one frame. The at least one frame describes at least one object and action involved in the situation in which the user has been involved and their relationship to each other. A context using the at least one frame is modeled by the context modeler so that when the context representation is applied to the database, operation of the database is adapted according to the situation.
