 Learn more about Unified Modeling Language in the online encyclopedia.
OMG has called for information on object-oriented methodologies, that might create a rigorous software modeling language.
Unified Modeling Language (UML) is a non-proprietary, third generation modeling language.
The Unified Modelling Language is an open method used to specify, visualise, construct and document the artifacts of an object-oriented software-intensive system under development.

 Object-Oriented Software Design and Programming [encyclopedia]
UML (Unified Modeling Language) is a standard notation for the modeling of real-world objects as a first step in developing an object-oriented program.
Objects provide a canonical focus throughout analysis, design, and implementation by emphasizing the state, behavior, and interaction of objects in its models, providing the desirable property of seamlessness between activities.
This is a feature-based or intensional definition, emphasizing a class as a descriptor/constructor of objects (as opposed to a collection of objects, as with the more classical extensional view, which may begin the analysis process).

In January 1997, UML was presented to the Object Management Group (OMG) in response to its request for a standard modeling technique.
UML standardizes several diagramming methods, including Grady Booch's work at Rational Software, Rumbaugh's Object Modeling Technique and Ivar Jacobson's work on use cases.
The Unified Modeling Language (UML) is the successor to the wave of object-oriented analysis and design (OOA&D) methodes that appeared in the late '80s and early '90s.

 The Unified Modeling Language Reference Manual (Addison-Wesley Object Technology Series)
He is the chief developer of the Object Modeling Technique (OMT) and the lead author of the best-selling book Object-Oriented Modeling and Design.
The UML Reference Manual is organized into three parts: an overview of UML history and of modeling, a survey of UML concepts, and an alphabetical encyclopedia of UML terms and concepts.
Those who already know an object-oriented method, such as OMT, Booch, Objectory, Coad-Yourdon, or Fusion, should be able to read the Reference Manual and use it to understand UML notation and semantics; to learn UML quickly, they may nevertheless find it useful to read the User Guide.

 Comparison of Techniques
This was mitigated somewhat in the mid-1990's, with the introduction of the UML, a modeling technique intended to replace at least all the "object modeling" ones.
Regardless of the symbols used, data or object modeling is intended to do one thing: describe the things about which an organization wishes to collect data, along with the relationships among them.
This is true for object modeling notations as well as entity/relationship notations.

 DBMS Interview - September 1995
ORM is such a powerful technique that it's easier to do a metamodel using ORM than it is using ER.
Apart from the modeling extensions I've alluded to, we're working on conceptual query languages so you can not only specify the model, but you can query the model directly at a conceptual level.
These roles may be played in isolation (for example, a person jogs) or as parts in relationships (if a person writes a book, the person plays the writing role and the book plays the role of being written).

The granularity of synchroniza- tion for synthetic composition is determined by the size of the objects in the hierarchy; however, this technique is not intended for providing continuous relationship composition.
The object composition layer is responsible for providing synchronization at the level of objects with an algorithm suitable to support real-time presentation of concurrent media to the application.

 JOT: Journal of Object Technology - Special Issue Use Case Modeling at UML-2004, Aug 2005
Use case modelling is widely used as a technique for requirements gathering but does not always lead to clear agreement between users and developers, or to effective system development.
We also propose a notion of use case (a coordinated use of system operations) that is very close to the traditional protocol, therefore concluding that use cases and protocols are not essentially different things.
As a consequence, the UML standard confuses use case specifications, types, and instances, as well as confusing a use case model with what it is a model of.

 Summary of Engineering Research
Procedural solid textures simulate the appearance of objects sculpted from wood and stone and are also useful for modeling clouds, water, fire, and planets.
This project has developed a new technique for simulating the procedural solid textures in real-time on recent consumer graphics cards, thus improving the realism of graphics used for video games, virtual environments, and modeling/animation software.
Using such simplification algorithms, researchers can also construct new multiresolution representations for surfaces that allow the application to treat an object at many different levels of detail.

 Introduction to Object Modeling Technique (OMT)
Object Modeling Technique (OMT) involves Systems Analysis and Systems Design, based on three different but complementary views of the system: Object, Dynamic and Functional Modeling.
The output from analysis is a formal model that captures the three essential aspects of the system: the objects and their relationships, the dynamic flow of control, and the f unctional transformation of data subject to constraints.
Basic algorithms are chosen to implement each major function of the system, the structure of the object model is then optimized, the implementation of each association and attribute is determined.

 OSA Tutorial
OSA is an objected-oriented systems analysis technique, which we understand as the study of a specific domain of interacting objects for the purpose of understanding and documenting their essential characteristics.
Analysis through the construction of system models, whose modeling constructs are based on formal definitions, is helpful for the following reasons.
It is also difficult for process-oriented analysis to map concepts between a network of processes and objects existing in a real-world system.
