Event partitioning : ウィキペディア英語版 | Event partitioning
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. == Overview == The Event partitioning approach is explained by Stephen M. McMenamin and John F. Palmer in ''Essential Systems Analysis''.〔MCME-84: (ISBN 978-0-13-287905-7)〕 A brief version of the approach is described in the article on Data Flow Diagrams. A more complete discussion is in Edward Yourdon's ''Just Enough Structured Analysis''.〔YOUR-89: (【引用サイトリンク】title=yourdon.com - ''Just Enough Structured Analysis'', Chapters 18, 19 )〕 The description focuses on using the technique to create data flow diagrams, but it can be used to identify use cases as well. The premise of event partitioning is that systems exist to respond to external events: identify what happens in the business environment that requires planned responses, then define and build systems to respond according to the rules of the business. In particular, a business system exists to service the requests of customers. A customer, in the jargon of the Unified Modeling Language (UML), is an ‘actor.’
