Smart blocks are ready packaged modules that you can import and use in your scenarios. They can accept inputs, execute some logic of their own, and generate output. In Apama's Event Modeler, in the Catalogs tab, you can view and select the smart blocks provided with Apama and CMF.

Complete information about developing scenarios is in the Apama document Developing Apama Applications. That document also includes information about the standard smart blocks provided with Apama. CMF provides additional smart blocks, which are described here.
