Modeling the Lifecycle of a Data Object

Hello All,

    We are wondering what options we should consider in ARIS to represent the lifecycle of a data object, for example, in a manufacturing process  ?   It looks like we may be able to use any of the following:

• OMT Dynamic Model 
• UML Statechart
• Event Diagram

     We feel the Event Diagram may be the best for our needs - has anyone used this or any of the other 2 Model Types for this ?   Also - any other Model types we should consider ?

   Thanks !
