Event Pattern Matching

In the previous tutorials you worked with Query statements that took input rows and manipulated the contents of those rows to produce output rows. A different goal for a Sybase CEP application can be to recognize when rows arrive in a specific sequence or pattern. For example, frequent repeated connection attempts from the same IP address may indicate a network security issue. A product passing the RFID sensors at a manufacturing facility in the wrong order may be the result of a process failure. Under certain circumstances, brokers placing a stock order for themselves just before placing an order for their customer may be illegal. This tutorial uses the last example to demonstrate how to write a CCL application to detect or match event patterns.
