The invention concerns a computer system for generating a web portal graphic interface, comprising a request manager (GR), designed to co-operate with a history manager (GH) and a graphic generator (GG) to display entities based on data stored in a database. The request manager (GR) reacts to the fact that an entity is pointed at by the user, by executing on the database an internal request, defined from a selected request expression, depending on the type of entity, and completed in accordance with the entity. This provides novel data, on the basis of which, the display is modified. The history manager (GH) interacts step by step with said request manager (GR), to construct a user request based on successive selections concerning the entities pointed at by the user on the graphic interface. The graphic generator (GG) then displays an adapted representation of the results produced by the request manager, in accordance with a predetermined format.
