<p>An object-oriented architecture for a factory floor management software system is described in which factory floor entities are modelled as factory objects within a relational database (66). The architecture includes X-terminal (50) or bar code devices (57) for facilitating user interaction with the system via one or more of the factory floor entities; application engines (52, 60) for processing user interaction of events and generating application service requests; and application servers (54, 55, 64) for processing the application service and generating database service requests in response. These database service requests are utilized to retrieve, manipulate and update data stored within the relational database. Communication managers (53, 61-63) are employed for coordinating interprocess communication between the application engines, the application servers and the database servers (65). Each of these major components are distributed among computer resources that are networked across the factory floor.</p> |
