Creating a Data Object
Data objects make it possible for actions to access data and store data.
Context
Data objects make it possible for actions to access data and store data.
Data stores are used for persistent data storage, with data buffers being used for temporary storage.
How to proceed
-
To indicate that data are saved persistently, click on the
Data Store Node icon in the Design>Create Diagram Content gallery.This tab contains the Create Diagram Content group.
- In order to indicate that data are only stored temporarily while the activity is being carried out, click on the
Central Buffer Node icon in the Design>Create Diagram Content gallery.
- Move the mouse in the diagram within the activity's frame.
-
Click the left mouse button where you want to position the node.
The data store or buffer node is created.
As the data type has not been specified yet, the node initially only shows the key word
«datastore»or«centralBuffer».You can change the data type directly using the
Properties tool window, or in the context menu for the data store or buffer node using the Assign Type command.
