So how does all this spatial magic happen? Let us now focus directly on the enabling features provided by the Oracle Event Processing technology, the Oracle Spatial Data Cartridge, and discuss how it can be used in a development context.
In previous chapters we have described the capability to extend the Oracle CQL CEP engine event analysis capabilities in many powerful and rich ways using Data Cartridges. This pluggable architecture also extends to integrate one of the leading industry spatial technology platforms provided with the Oracle Enterprise Edition Database.
The Oracle Spatial Data Cartridge encapsulates the major features of this technology and enables Oracle Event Processing developers to execute these spatial functions directly in the event language and thus can be modified dynamically and reintroduced into the application, changing its logic flow, without stopping and restarting the application.
As we have already introduced various bus tracking...
