Data streams can provide additional input to the Sybase CEP application and output streams which connect to external adapters.
In addition to this basic data stream, there are a number of other data streams that will be used in conjunction with the examples throughout this guide. Like StockTrades, some of these streams are data sources which provide additional input to the Sybase CEP application. Others are output streams which are the ultimate destination of information from a query. Some of these output streams would normally be connected to external adapters (such as an e-mail adapter or a JMS message queue), while others would be used solely inside the Sybase CEP engine to send data along to other Sybase CEP queries.
When these additional streams are first used in the guide, the associated schemas may be presented either in tabular or textual form.
