"Event partitioning is an easy-to-apply systems analysis technique that helps the analyst organize requirements for large systems into a collection of smaller, simpler, minimally-connected, easier-to-understand ‘mini systems’ / use cases. ...
Defining requirements.
Single process in a fictitious hotel using data flow diagram notation.
Single use case in a fictitious hotel using use case diagram notation.
This approach helps the analyst to decompose the system into ‘mentally bite-sized’ mini-systems using events that require a planned response. The level of detail of each response is at the level of ‘primary use cases’. Each planned response may be modelled using DFD notation or as a single use case using use case diagram notation.
The basic flow within a process or use case can usually be described in a relatively small number of steps, often fewer than twenty or thirty, possibly using something like ‘structured English’. Ideally, all of the steps would be visible all at once (often a page or less). The intention is to reduce one of the risks associated with short-term memory, namely, forgetting what is not immediately visible (‘out of sight, out of mind’). ...

How to Create a Data Flow Diagram

Data flow diagramming is a highly effective technique for showing the flow of information through a system. Data flow diagrams reveal relationships among and between the various components in a program or system. DFD is an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations. The set of standard symbols is used to depict how these components interact in a system. ConceptDraw DIAGRAM allows you to draw a simple and clear Data Flow Diagram using special libraries.
