數據驅動 vs 控制驅動

Data-driven concurrency（數據驅動併發）:

1.The system is modelled as a set of processes without any explicit specification of the ordering of executions. 不會定義排程的執行順序。

2.The execution order of processes (and, implicitly, the potential of parallelism) is fixed solely by data dependencies 排程的執行順序是依照數據的相關性。

Control-driven concurrency（控制驅動併發）:

1.The execution order of processes is given explicitly in the system model. 
在系統中已經明確指定執行順序。

2.Explicit constructs are used to specify sequential execution and concurrency. 
明確的結構用於指定順序執行和並發性。
