UML Designer User's Guide
To start working in UML Designer, select Relationships Browser
from the UML Designer menu in the Transcript window. The
Relationships Browser opens.
The Relationships Browser shows the available models, the design elements
in each model, and the relationships that exist among them. From here,
you can create new design elements, browse and modify their relationships, and
launch the other UML Designer browsers and editors. (For more
information about the Relationships Browser, see The Relationships Browser.)
When you first install UML Designer, three models are automatically
included:
- Kernel Model includes design elements for some
implementation-independent common data types.
- Kernel Model--Java Examples includes design elements for
Java data types.
- Kernel Model--Smalltalk Examples includes design elements
for Smalltalk data types.
Since you're likely to need some of the basic data types in any system
you design, UML Designer, by default, makes the Kernel Model and
Kernel Model--Smalltalk Examples prerequisites for any models
you create. (If you want to use Java data types, you will need to
manually add Kernel Model--Java Examples as a
prerequisite.) This means that the basic Smalltalk classes in the
Kernel models are automatically visible from any other
model.
To begin modeling a new system, you must first create a new model in the
Relationships Browser:
- Select Create Model from the Source menu, or from
the pop-up menu in the leftmost pane in the Relationships Browser.
- When prompted, specify the following information about the new
model:
- The specification name of the model. This can be any name you want
to use to identify the model. Our example will be a system to catalog
library books, so type Library Catalog.
- The namespace prefix for the model. This is an arbitrary string
that will be used as a prefix to uniquely identify the model and its elements
in the Smalltalk repository. You can accept the default value for this
prefix, or you can add your initials or some other unique identifier if you
share the same repository with other users.
- The Smalltalk application name for the model. This is the name that
will be used for the application containing the model elements. You
will not normally need to access this application directly, so in most cases
you can accept the default application name, which is the model name appended
to the namespace prefix.
- Select OK. The new model appears in the list in the Relationships
Browser.
