  Unified Modeling Language version 2.0
For instance, in UML 1, the notion of ownership (that is, elements owning other elements), the concept of namespaces (named collections of uniquely named elements), and the concept of classifiers (elements that can be categorized according to their features), were all inextricably bound into a single semantically complex notion.
In UML 2.0, all of these concepts were aligned, so that components were simply defined as a special case of the more general concept of a structured class; similarly, subsystems were merely a special case of the component concept.
The language structure was carefully reorganized to allow a modular and graduated approach to adoption: you only need to learn the parts of the language that are of interest to you, and can safely ignore the rest.

 The Unified Modeling Language
UML was well received by the industry, and it slowly became a defacto standard in the modeling community.
The UML meta model is the language used to describe models, and a model is an instance of the meta model.

 Introduction to OMG UML
In fact, a UML model can be either platform-independent or platform-specific, as we choose, and the MDA development process uses both of these forms: Every MDA standard or application is based, normatively, on a Platform-Independent Model (PIM), which represents its business functionality and behavior very precisely but does not include technical aspects.
Improved Behavioral Modeling: In UML 1.X, the different behavioral models were independent, but in UML 2.0, they all derive from a fundamental definition of a behavior (except for the Use Case, which is subtly different but still participates in the new organization).
That is, the new language goes well beyond the Classes and Objects well-modeled by UML 1.X to add the capability to represent not only behavioral models, but also architectural models, business process and rules, and other models used in many different parts of computing and even non-computing disciplines.

 Unified Modeling Language FAQ   (Site not responding. Last check: 2007-10-22)
The Unified Modeling Language represents the unification of the Booch, Objectory, and OMT methods and is their direct and upwardly compatible successor.
Because we were in effect designing a new language (albeit a graphical one), we had to strike a proper balance between minimalism (everything is text and boxes) and overengineering (having an icon for every conceivable modeling element).
It is most likely that tools will stage their support for the Unified Modeling Language either by starting with use cases first, plus perhaps a few other things (like the cosmetics of the graphical syntax and possibly stereotypes and properties), or by supporting simple semantics first and then adding deeper semantic support later.

 Be Realistic About the UML: It's Simply Not Sufficient
A new UML Profile for Physical Data Modeling is published at www.agiledata.org (the good news is that in December 2005 the OMG announced an RFP for data-oriented models).
Although the UML defines an important collection of models, I highly suggest adopting them in accordance with the practice Apply Modeling Standards, the reality is that the UML has narrowed the range of discussion within the modeling community.
Yes, sometimes it is possible to use UML diagrams in situations for which they really weren’t intended, for example it is quite common to use UML Activity diagrams to model business processes as you see in Figure 2, this often proves less than ideal.

 Types of UML Diagrams - Unified Modeling Language (UML)
Today, UML is accepted by the Object Management Group (OMG) as the standard for modeling object oriented programs.
UML defines nine types of diagrams: class (package), object, use case, sequence, collaboration, statechart, activity, component, and deployment.
Statechart diagrams are especially useful in modeling reactive objects whose states are triggered by specific events.

In The Unified Modeling Language User Guide, the original developers of the UML, Grady Booch, James Rumbaugh, and Ivar Jacobson, provide a tutorial to the core aspects of the language in a two-color format designed to facilitate learning.
Applying UML and patterns is more of a patterns book than a UML tutorial, and it provides a good introduction to o-o analysis and design that has a slightly different slant than other books on the subject.
Overall it champions the use of patterns, a technique that leads to the standardisation of modelling using the UML and allows more novice developers to stand on the shoulders of the more experienced, and incorporate good practice into their own designs.

 Amazon.com: The Unified Modeling Language User Guide: Books: Grady Booch,James Rumbaugh,Ivar Jacobson   (Site not responding. Last check: 2007-10-22)
The authors pay close attention to modeling classes (and documenting the relationships between classes) as well as use case diagrams (which show how software will be used by various actors in a system).
They fail to mention quite a few of the new UML features (the X navigation adornments that make non-navigability explicit, for example, which is critical to code generation, or the fact that you can have multiple stereotypes associated with model elements.
In their defense, the UML standard isn't very clear on these diagram types, but this is a practical tutorial that should take practice into account.

 UML and Modeling Methodologies
Domain-specific modeling is most successful when the models let you generate complete working code, without the need for post-generation code modifications or additions.
Domain-specific modeling promises to change the modeling landscape by providing a greater level of abstraction from code than UML, providing modeling constructs for developers that mimic the real-world objects more closely, and most importantly, providing complete code-generation capabilities, which together lead to a much more productive way for developers to model applications.
UML models of the future will use XMI as a method of interchanging model data.

The analysis model is built from a well-defined subset of the UnifiedModelingLanguage with the addition of action specifications behind class methods and on entry/exit to states.
These action specifications are written in ASL, which appears to be a procedural OO language that looks, to me, more like AppleScript than anything else.
Then you hit the button, and the code generator uses the rules in the design model to implement the analysis model.
