UML (graphical) Notation

The UML (Unified Modeling Language) notation is a specification language

for object models.

It is a graphical-textual language.

It is not a programming language.

It has a semantics but not an operational semantics.

UML has been agreed to as the “standard” language for

describing (modeling) objects.

UML is intended to scale to support specification of large complex

systems. Accordingly it is baroque and complicated. We

will use only a small part of UML which we will introduce

as we go along rather than spending separate lecture

time on UML.

Developers are working on an subset of UML which can be

given an operational specification. That is, it will

be possible to write a compiler which will translate

UML to executable code.

We will use UML as a documentation language to supplement

English.
