Set the Context for Universal Domination in a DFD<\/h2>\n

Happy Star Wars day 2017<\/p>\n

Whatever your Systems Engineering tasks you can use diagrams to illustrate the various components. In classic functional modelling<\/a> the Essential domain<\/em> shows the operational, theoretical, side of the design, and the Implementation domain<\/em> models the actual real world components.<\/p>\n

\"Data
Death Star DFD<\/figcaption><\/figure>\n

The Context Diagram<\/span><\/span><\/em> shows the entire system or subsystem as one process with the exchanges of information between it and its environment.\u00a0 In today’s example, this is the ‘Death Star<\/a>‘ , the external environment being the universe!<\/p>\n

From the context diagram a set of hierarchical Data Flow Diagrams (DFDs) <\/a>give a view of units of functionality and the exchanges of data<\/span><\/span> between these units. So we would expect DFDs covering the Emperor’s Tower, Surface City, Superlaser Focus Lens<\/em> and so on. So May the Fourth Be With you, and all your modelling.<\/p>\n
