IBM SG24-7368-00 manual Logical entities

￿One example (see Figure 6-8 on page 101) would consist of copy/pasting the ${actor.name} package to the Actors package. Right-click on the pasted package and select Find/Replace. Change the placeholder name to the name of the actor. This will change the placeholder everywhere it exists under that package. (In the future this is being considered as an area for automation within the MDSD plug-in).

￿Within the Actors package is a place for a diagram containing all of the actors. Also, if you want to show all the actors along with any operations they contain, this can be shown in another diagram.

Figure 6-9 An actor with its connected I/O entities (the entity that it is connected to in any context diagram (the enterprise) is also shown)

Logical entities

At the top, or Enterprise, level there is only one entity, so it is a simple case. Under the Logical Elements folder is the element representing that entity, in this case a class, along with a context diagram. If the element has many operations as a result of use case analysis, then add an operations diagram, which is just the element with its operations displayed. Displaying them in the context diagram would make it cluttered.
