What is Activity Diagram?<\/h3>\n

5-7 minutes<\/p>\n

When to Use Activity Diagram<\/h3>\n

Activity Diagrams describe how activities are coordinated to provide a service which can be at different levels of abstraction. Typically, an event needs to be achieved by some operations, particularly where the operation is intended to achieve a number of different things that require coordination, or how the events in a single use case relate to one another, in particular, use cases where activities may overlap and require coordination. It is also suitable for modeling how a collection of use cases coordinate to represent business workflows<\/p>\n

    \n
  1. Identify candidate use cases, through the examination of business workflows<\/li>\n
  2. Identify pre- and post-conditions (the context) for use cases<\/li>\n
  3. Model workflows between\/within use cases<\/li>\n
  4. Model complex workflows in operations on objects<\/li>\n
  5. Model in detail complex activities in a high level activity Diagram<\/li>\n<\/ol>\n

    Activity Diagram – Modeling a Word Processor<\/p>\n

    The activity diagram example below describes the workflow for a word process to create a document through the following steps:<\/p>\n

      \n
    • Open the word processing package.<\/li>\n
    • Create a file.<\/li>\n
    • Save the file under a unique name within its directory.<\/li>\n
    • Type the document.<\/li>\n
    • If graphics are necessary, open the graphics package, create the graphics, and paste the graphics into the document.<\/li>\n
    • If a spreadsheet is necessary, open the spreadsheet package, create the spreadsheet, and paste the spreadsheet into the document.<\/li>\n
    • Save the file.<\/li>\n
    • Print a hard copy of the document.<\/li>\n
    • Exit the word processing package.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
