The first phase of building the DEMIS defines the baseline objects of the enterprise and their associations to each other. These baseline objects and their associations would be documented and stored in the DEMIS MIB. This diagram highlights the major tasks of that phase.
The principal workload in building and maintaining the MIB baseline inventory is collecting, organizing, and maintaining the object class and instance attributes, profiling relationships, and their data values.
However, this workload, and the data that results from it, is already present in any enterprise management efforts. The DEM approach can decrease the amount of that workload, while making the workload's products more useful and accessible.
The difference with the DEM approach is its unitary perspective, process, and control. Other approaches from a more fragmented perspective will have greater resultant overhead cost for processing, collection, dissemination, synchronization, validation, storage, transport, security, and presentation of that same data.
We create an important and usable product with each DEMIS Stage I implementation task and its integration with preceding task results. I describe the tasks and their products in subsequent charts.
