UML deployment diagram
depicts a static view of the run-time configuration of hardware nodes and the
software components that run on those nodes.
Deployment diagrams show the hardware for your system, the software that
is installed on that hardware, and the middleware used to connect the disparate
machines to one another. You create
a deployment model to:
the issues involved with installing your system into production.
the dependencies that your system has with other systems that are currently
in, or planned for, your production environment.
a major deployment configuration of a business application.
the hardware and software configuration of an embedded system.
the hardware/network infrastructure of an organization.
There are guidelines for:
Nodes and Components
and Communication Associations

2 is an example a style of UML Deployment diagram often referred to as a
network diagram or technical architecture diagram, depicting the technical
infrastructure of a simple organization.
2 is a very simple example, many
organizations would have tens if not hundreds of nodes on such a diagram.
A node, depicted as a three-dimensional box, represents a
computational unit, typically a single piece of hardware, such as a computer,
network router, mainframe, sensor, or personal digital assistant (PDA).
In UML 2 nodes can also be software.
represent software artifacts such as file, framework, or domain component.
- Name Nodes With Descriptive Terms
- Model Only Vital Software Components
- Apply Consistent Stereotypes to Components
- Apply Visual Stereotypes to Nodes
Communication associations, often called connections, are
depicted as lines connecting nodes. Dependencies between components are modeled
as dashed arrows, the same notation used on other UML diagrams.
- Indicate Communication Protocols Via Stereotypes
- Model Only Critical Dependencies Between Components
The Elements of UML 2.0 Style describes a collection
of standards, conventions, and
for creating effective
UML diagrams. They are based on sound, proven
software engineering principles that lead to diagrams
that are easier to understand and work with. These
conventions exist as a collection of simple, concise
guidelines that if applied consistently, represent an
important first step in increasing your productivity as
a modeler. This book is oriented towards
intermediate to advanced UML modelers, although there
are numerous examples throughout the book it would not
be a good way to learn the UML (instead, consider
The Object Primer). The book is a brief 188
pages long and is conveniently pocket-sized so it's easy
to carry around.
The Object Primer 3rd Edition: Agile Model Driven
Development with UML 2 is an
important reference book for agile modelers,
describing how to develop 35
types of agile
models including all 13
UML 2 diagrams.
Furthermore, this book describes the techniques
Full Lifecycle Object Oriented Testing
(FLOOT) methodology to give you the fundamental
testing skills which you require to succeed at
agile software development. The book also
shows how to move from your agile models to
source code (Java examples are provided) as well
as how to succeed at implementation techniques
(TDD). The Object Primer also includes a
chapter overviewing the critical database
development techniques (database refactoring,
legacy analysis, and
database access coding) from my award-winning
Agile Database Techniques
Agile Modeling: Effective Practices for Extreme
Programming and the Unified Process is the seminal
book describing how agile software developers approach
documentation. It describes principles and
practices which you can tailor into your existing
software process, such as
Rational Unified Process (RUP), or the
Agile Unified Process (AUP), to streamline your
modeling and documentation efforts. Modeling and
documentation are important aspects of any software
project, including agile projects, and this book
describes in detail how to
architect, and then
design your system in an agile manner.
We actively work with clients around the world to
improve their information technology (IT) practices,
typically in the role of mentor/coach, team lead, or trainer. A full
