Event driven or Request-Response SOA - a practical application

Hi,

 

After reading 10 articles over the last couple of days, I need some practical input about how to define service communication in SOA - just a general example would be great.

 

For example, consider a Car rental company that has these two services.For all methods it must be possible to consume using ordinary soap clients and CreateCarReservation must create a customer using CreateCustomer.



Car service: GetCarList, CreateCarReservation

Customer service: CreateCustomer
 
I wonder how you would define the communication here? I'm thinking practical example, what async events, sync resquest/responses do you see?
