The chat beheld in the analogue is a key point—the UML is the de facto accepted diagramming characters for cartoon or presenting pictures (with some text) accompanying to software—primarily OO software.

This book doesn’t awning all minute aspects of the UML, a ample anatomy of notation. It focuses on frequently acclimated diagrams, the best frequently acclimated appearance aural those, and core characters that is absurd to change in approaching UML versions.

The UML defines assorted UML profiles that specialize subsets of the characters for accepted accountable areas, such as diagramming Enterprise JavaBeans (with the UML EJB profile).

At a added level—primarily of absorption to Archetypal Driven Architecture (MDA) CASE apparatus vendors—underlying the UML characters is the UML meta-model that describes the semantics of the clay elements. It isn’t commodity a developer needs to learn.

In [Fowler03] three means bodies administer UML are introduced:

UML as sketch— Informal and abridged diagrams (often duke sketched on whiteboards) created to analyze difficult genitalia of the botheration or band-aid space, base the ability of beheld languages.

UML as blueprint— Relatively abundant architecture diagrams acclimated either for 1) about-face engineering to anticipate and bigger compassionate existing cipher in UML diagrams, or for 2) cipher bearing (forward engineering).

There is a acclaimed cardboard from 1986 blue-blooded “No Argent Bullet” by Dr. Frederick Brooks, additionally appear in his archetypal book Mythical Man-Month (20th ceremony edition). Recommended reading! An capital point is that it’s a axiological aberration (so far, endlessly repeated) to accept there is some appropriate apparatus or address in software that will accomplish a affecting order-of-magnitude aberration in productivity, birthmark reduction, reliability, or simplicity. And accoutrement don’t atone for architecture ignorance.

Yet, you will apprehend claims—usually from apparatus vendors—that cartoon UML diagrams will accomplish things abundant better; or, that Archetypal Driven Architecture (MDA) accoutrement based on UML will be the advance argent bullet.

Reality-check time. The UML is artlessly a accepted diagramming notation—boxes, lines, etc. Beheld clay with a accepted characters can be a abundant aid, but it is hardly as important as alive how to architecture and anticipate in objects. Such architecture ability is a actual altered and more important skill, and is not baffled by acquirements UML characters or application a CASE or MDA tool. A being not accepting acceptable OO architecture and programming abilities who draws UML is aloof cartoon bad designs. I advance the commodity Death by UML Fever [Bell04] (endorsed by the UML architect Grady Booch) for added on this subject, and additionally What UML Is and Isn’t [Larman04].

Therefore, this book is an addition to OOA/D and applying the UML to abutment accomplished OO design.

If about-face engineering, a UML apparatus reads the antecedent or binaries and generates (typically) UML package, class, and arrangement diagrams. These “blueprints” can advice the clairvoyant accept the big-picture elements, structure, and collaborations.

Before programming, some abundant diagrams can accommodate advice for cipher bearing (e.g., in Java), either manually or automatically with a tool. It’s accepted that the diagrams are acclimated for some code, and added cipher is abounding in by a developer while coding (perhaps additionally applying UML sketching).

UML as programming language— Complete executable blueprint of a software arrangement in UML. Executable cipher will be automatically generated, but is not commonly apparent or adapted by developers; one works alone in the UML “programming language.” This use of UML requires a applied way to diagram all behavior or argumentation (probably application alternation or accompaniment diagrams), and is still under development in agreement of theory, apparatus robustness and usability.

Agile clay emphasizes UML as sketch; this is a accepted way to administer the UML, generally with a aerial acknowledgment on the advance of time (which is about short). UML accoutrement can be useful, but I animate bodies to additionally accede an active clay access to applying UML.

The UML describes raw diagram types, such as chic diagrams and arrangement diagrams. It does not blanket a clay perspective on these. For example, the aforementioned UML chic diagram characters can be acclimated to draw pictures of concepts in the absolute apple or software classes in Java.

This acumen was emphasized in the Syntropy acquisitive adjustment [CD94]. That is, the aforementioned characters may be acclimated for three perspectives and types of models (Figure 1.6):

Conceptual perspective— the diagrams are interpreted as anecdotic things in a bearings of the absolute apple or area of interest.

Blueprint (software) perspective— the diagrams (using the aforementioned characters as in the conceptual perspective) call software abstractions or apparatus with blueprint and interfaces, but no charge to a accurate accomplishing (for example, not accurately a chic in C# or Java).

Accomplishing (software) perspective— the diagrams call software implementations in a accurate technology (such as Java).

Figure 1.6 Altered perspectives with UML.

We’ve already apparent an archetype of this in Figure 1.3 and Figure 1.5, area the aforementioned UML chic diagram characters is acclimated to anticipate a area archetypal and a architecture model.

In practice, the blueprint angle (deferring the ambition technology, such as Java against .NET) is hardly acclimated for design; best software-oriented UML diagramming assumes an accomplishing perspective.

In the raw UML, the ellipsoidal boxes apparent in Figure 1.6 are alleged classes, but this appellation encompasses a array of phenomena—physical things, abstruse concepts, software things, events, and so forth. [1]

A adjustment superimposes another analogue on top of the raw UML. For example, in the UP, back the UML boxes are fatigued in the Area Model, they are alleged area concepts or conceptual classes; the Area Archetypal shows a conceptual perspective. In the UP, back UML boxes are fatigued in the Architecture Model, they are alleged architecture classes; the Architecture Archetypal shows a blueprint or accomplishing perspective, as adapted by the modeler.

To accumulate things clear, this book will use class-related agreement constant with the UML and the UP, as follows:

Conceptual class— real-world abstraction or thing. A conceptual or capital perspective. The UP Area Archetypal contains conceptual classes.

Software class— a chic apery a blueprint or accomplishing angle of a software component, behindhand of the action or method.

Accomplishing class— a chic implemented in a specific OO accent such as Java.

Towards the end of 2004 a above new absolution of the UML emerged, UML 2. This argument is based on UML 2; indeed, the characters acclimated actuality was anxiously advised with key associates of the UML 2 blueprint team.

This is not primarily a UML characters book, but one that explores the beyond account of applying the UML, patterns, and an accepted action in the ambience of OOA/D and accompanying requirements analysis. OOA/D is commonly preceded by requirements analysis. Therefore, the antecedent capacity acquaint the important capacity of use cases and requirements analysis, which are again followed by capacity on OOA/D and added UML details.
