Exercise 6 - System Decomposition
In this exercise, you create three activity-charts that show the decomposition of the top-level activity-chart that was developed in Exercise 4 - Constructing an Activity-Chart. The same modeling techniques should be used in this exercise as in Exercise 4. The following three figures show the three activity-charts that need to be created.
1.
Note: During the following step, you need to create the relationship between the activity-charts that have been created within the exercises.
2. Open the chart called 'REAR_DEFOG_SS' and modify the name of the activity called 'REAR_DEFOG_FEATURES' by adding a '@' symbol to the beginning of the name.
3. Once the '@' symbol has been added to the activities name, select the activity and then select File > Open Sub-Chart.
4. From within the activity-chart REAR_DEFOG_FEATURES, edit the names of the activities CALC_REAR_DEFOG_STATE and REAR_DEFOG_RELAY_MGMT by adding a '@' symbol to the beginning of their names.
Note: You also need to define the textual element added to the activity-chart REAR_DEFOG_FEATURES called 'RDEFOG_ON_STATUS'.

6. Change the Type from Information Flow to Condition.
