PROJECT MANAGEMENT SYSTEM

摘要

A project management system comprises a database (2) for storing objects relating to a project together with data defining interdependencies of the objects. A control system (1) responsive to entities (5) connected to it provides access to selected objects stored on the database (2) and stores on the database (2) updated versions of selected objects received from the entities (5). The control system (1) is adapted to produce copies of an object that has been accessed by a first entity and all objects that are interdependent on that object if that object or an object that is interdependent on that object is modified by a second entity between the object being accessed by the first entity and an updated version being received by the database.
