Description
The StockTrader Order Processor Service is responsible for performing final processing of orders that are submitted by the StockTrader Client. The StockTrader Business Service receives each buy and sell order from the StockTrader Client, and then submits them directly to the StockTrader Order Processor Service. The StockTrader Order Processor Service then will retrieve the current stock price, and record the order in the StockTrader Database at the current price. All of the operations are performed asynchronously.
