Explain about precedence constraint in SISS

In any coding language or back-end application, a task is executed only after satisfying a set of parameters. Only then the task is assigned on a path that is suitable to complete the given command. In SISS too there are parameters that define the path of a task. A precedence constraint is a task sequence that is defined by a logical statement or a command. It is in this sequence a task is being performed. We can also use a connector to connect these tasks and precedence constraints.

• Completion

It is mandatory for the preceding container to get executed completely. The result may be a success or a failure. Only when it is completed, the current workflow starts preceding.

• Success

If the preceding container has completed execution and is also successful, then it is represented by a green line.

• Failure

When the preceding container is executed but failed then it is marked with a red line.
