• For theoretical introduction and other information, read the following article: ARD
• The ARD design is supported by tools:
  • VARDA
  • HJed
• During this lab classes the HJEd tool will be used.

• HJEd is a tool that supports the ARD design method.
• It is a GUI-based tool written in JAVA.

• In this exercise the model of the Cashpoint system will be designed. The design starts with the empty diagram. The goal of this lab is to design the following structure:
  
• The ARD method is a herarchical method. Each level of the desing can be called as the seperate step of the design.
• Each step consists of one and only one transformation (split or finalization).
• To build a complete model of the CashPoint system a several steps must gone through.
• Each step changes both ARD and TPH diagrams.
• On this page: ard_full_design the ARD as well as TPH diagrams of the CashPoint system after each step can be found.
• Here a instructions for first three step are presented. The rest of the design process is analogous.
  1. Run HJEd by typing

     java -jar HJEd.jar

     You should see the main window of the tool as presended above.

     • On the left panel a current level of a ARD diagram can be observed.
     • On the right panel a current TPH diagram is presented.
     • Only the left panel allows for interaction with user, and can be used to design.
  2. Click with the RMB on the left panel and click Add root action:
     
  3. In the window type the name of the most general attribute describing the system. We call him CashPoint:
     
  4. In the both panel a single property containing the CashPoint attribute can be observed.
  5. In the next step, the finalization transformation will be done.
     Click on this property with RMB and select Finalization action:
     
  6. In the window add a three new attributes: UserRequestedAction, ActionEnvironment, CashPointActivity. Type the name in the New attribute field and click Add:
     
  7. After when you click OK, the contents of the diagrams will change again:
     • On the ARD diagram, only the last level containing a finalized property is depicted.
     • On the TPH diagram, the transition between stages can be observed.
  8. According to the
