摘要： A method and a system for accessing data in a computer-based data processing system. The method comprises the steps of initiating and maintaining data access nodes in a variable access structure. Each access node is provided with references to other access nodes and/or to data items representing an object, each data item carrying only the amount of information which is relevant for its purpose. The data items or the references are provided with a time parameter thus enabling version control and the possibility to handle static or slowly changing data and frequently changed and updated data in a conform manner. The access nodes comprises access control parameters for access control from safety point of view as well as for enabling different views of the access structure and underlying data and objects.
