| + | * Use the Constructionist Design Methodology to achieve a good system architecture design | ||
| + | * Run the system on Gola and be ready to demonstrate it on Gola in class | ||
| + | * Use whiteboards and message types sensibly to achieve an efficient yet flexible architecture | ||

| Consider the trading of a single commodity through a double auction market process. A double auction is a process in which buyers and sellers can freely enter limit orders (bids or asks) and accept bids or asks entered by others. It is the organization used in major exchange markets around the world trading stocks, commodities or currencies. | Consider the trading of a single commodity through a double auction market process.
