EventStudio is a tool for modeling object and message interactions. Specify the design in a modeling language. EventStudio visualizes the design with sequence diagrams at multiple abstraction levels. Model multiple scenarios by just specifying the differences from a base scenario.

1. Model with sequence
diagrams
Capture complex system
interactions with sequence
diagrams.

2. Powerful yet simple modeling language
Represent messages, method calls, timers, state transitions, actions, and resources.
A B
eternal: A, B /* Eternal objects */
Message
x = Value, field
dynamic: C /* Dynamic objects */
MessageResponse
feature "Sample"
Message (x = "Value", field): A -> B
Method()
par1, par2
MessageResponse: A <- B
returns
A invokes B.Method(par1, par2)
B.Method returns
create C
A creates C
Initializing C
A, C take action "Initializing C"
Starting up
A state = "Starting up"
A deletes C
delete
endfeature
