## 11.3 Data


A **Choreography** does not have a central control mechanism and there is no mechanism for maintaining any central **Process** (**Choreography**) data. Thus, any element in a **Process** that would normally depend on conditional or assignment expressions, would not have any central source for this data to be maintained and understood by all the *Participants* involved in the **Choreography**. As mentioned above, neither **Data Objects** nor **Repositories** are used in **Choreographies**. Both of these elements are used exclusively in **Processes** and require the concept of a central locus of control. **Data Objects** are basically variables and there would be no central system to manage them. *Data* can be used in *expressions* that are used in **Exclusive Gateways**, but only that data which has been sent through a **Message** in the **Choreography**.
