Management Support Systems




                    Notes          Directory: It is a catalog of all the data in a database or all the models in a model base.
                                   Model Base: It is a collection of pre-programmed quantitative models (e.g., statistical, financial,
                                   optimization) organized as a single unit.

                                   Model Building Blocks: Model building blocks are Pre-programmed software elements that can
                                   be used to build computerized models.
                                   Process: The term “process” in the context of user interface process refers to the flow of information
                                   (a) from the user to the system and (b) from the system to the user.
                                   Query Facility: It is the (database) mechanism that accepts requests for data, accesses them,
                                   manipulates them, and queries them.
                                   User Interface Management System (UIMS): The UIMS processes user commands, issued in
                                   whatever action language it requires, and passes them on to the data and model management
                                   subsystems.
                                   User Interface: User interface is the vehicle for both model construction (or model choice) and
                                   for investigating the results.
