25. Platform - Long Running Transaction or Document Workflow

  • Document workflow is handled by a module consisting of a workflow log, a workflow engine and a model of states and transitions

  • Documents go through a sequence of stages based on user input

  • The state of the document needs to be persistent and available to the application

  • Document state information is stored in XML format in either a database or on filesystem

  • The engine processes the workflow request; records, updates and answers queries regarding a document's state
