Data and Artifacts
This section covers the simulation settings of the elements Data Object and Data Store.
Data Object
Data Objects are used as Data Input or Output. You can stick them to activities, and depending on the Association flow’s direction, the Data Objects act either as an input (association flow in) or as an output (association flow out), or both.
Optional Simulation Properties
- Expression
-
In this text box you can define custom attributes (e. g
x=5), or operations that shall be executed in this activity (e. g. a Python-script).
See Model 3d - Data Objects from the Simulation Tutorial for an example. - Stochastic Attribute Assignment
-
In addition to Expression field, this option gives you the possibility to use one of our stochastic distributions to calculate the value of an attribute
-
E. g. x gets its value form the Normal Distribution with the parameters: Mean-Value = 4, Standard-Deviation = 1
-
See Model 3c - Inclusive Gateways from the Simulation Tutorial or Assigning Process Variables for examples.
-
Data Store
The data store holds data, which is being written to it by the model’s entities. Once a data entry is present in the data store, it can be read and manipulated.
-
Use Data Associations to write / read to / from a data store
-
See Data Associations for more information on transferring data
-
Or see Model 3e - Data Stores from the Simulation Tutorial for an example.
