....and in the definition of use case, they are sequential. Also, in both definitions, the activities are aimed at delivering a particular result. In addition to the similarities that exist between the definitions, it has been noted that business processes can be described by use case models [15, 10, 11, 16]. These observations give rise to the assumption that it is possible to translate business process models to use case models. The benefit of having such a technique is that, while use cases have to be captured by performing interviews in an organization, business processes are often available in ....

....is represented by a dashed arrow, labeled #extend#. Each use case can be described in detail, by describing the interactions between the actors and the system, and the order in which they occur. Many description techniques exist to detail a use case. We could, for example, use state machines [16], or activity diagrams [9] In this paper we use numbered lists to model a use case s interactions and their order. If two numbers occur twice, this models a choice between two possible interactions. The use case enter mortgage in figure 1 could, for example, be detailed by the numbered list in ....

....in an efficient manner. Thus, communication between humans represents a crucial aspect for the success of large software development projects. Communication on the level of detailed software design is well understood. For this level of abstraction the Unified Modeling Language (UML) 1] [2] has become a widely accepted de facto standard in research and industry. On higher levels of abstraction, communication concerning what is generally known as the architecture of a system remains difficult and uncertain [3] The commonly used object oriented approach reflects conceptual problems ....

....software systems. It represents a collection of the best engineering practices that have proven successful in modeling of large and complex systems. This has become de facto industrial standards as a modeling language and the most recent documentation was made in June, 1999 as version 1. 3 [3]. Rational Software [13] developed UML RT (UML Real Time) which is not yet included in the standard UML 1.3 by OMG. It has been developed to address a category of systems that are characterized as complex, event driven, and potentially distributed. A set of new modeling constructs has been added ....

....is to organize (modularize, partition and package) meta models. Applicable mechanisms here are generalization, nesting, import and clustering. The MOF specification defines these concepts as well as other, supporting concepts in detail. Because there is no explicit notation for MOF, the UML [7] notation has been deliberately used to visualize selected concepts. The interface to the conceptual framework of MOF is formally defined in the CORBA IDL modules Model (meta model specific interfaces) and Reflective (generic interfaces) All interfaces in Model directly or indirectly inherit from ....

....to inform the observer. The model for that example is formalized using a suitable notation. Though different notations could be used to model the same system, even using the same modeling concepts, we have decided to provide an UML profile(Unified Figure 4. A Configuration Tool Modeling Language, [7]) for the notation of models based on our concpt space. UML is standardized by the Object Management Group (OMG) and is used in the development process of many object oriented and component based systems. Integrating a number of known object oriented methods, such as Objectory, OMT, Booch, UML ....

The proposals of this paper are based on the ITU T QoS framework [14] that provides basic QoS concepts and principles for distributed object based applications) and the Unified Modeling Language, UML [8] (that is extended in order to support the mentioned QoS concepts and principles during different modeling activities of different development processes) This paper proposes two complementary extensions to UML: The first one (called UML Q) would allow, for instance, specifying (at design ....

.... UML is a general purpose modeling language, it contains extensibility mechanisms that can be used to tailor it to specific domains (QoS information specification, for instance) These extensibility mechanisms can be understood as indirect modification, at the model level, of the UML meta model [8]. The standard extensibility mechanisms of UML are stereotypes, tagged values and constraints . These extensibility mechanisms are called lightweight extensibility mechanisms [1] in contrast to the direct manipulation of the UML meta model that can be interpreted as heavyweight extensibility ....

Simulating roles by composition Roles in Collaborations Finally, UML 1.3 incorporates the notion of classifier roles in collaboration diagrams. According to UML 1. 3 [9], a collaboration describes how an operation or a classifier is realized by a set of classifiers and associations used in a specific way. In UML 1.3 (see [9] page 3 113) it is distinguished between two forms of a collaboration diagram, one at an instance level and one at specification level. ....

....as a column header in tabular printouts of the relationship s extent. The entity relationship (ER) model [14] and many of its extensions take up the practice of assigning role names to the entity types participating in relationships. In object oriented analysis and design languages (including UML [48]) whose static models are based on the ER model, it has become common to drop relationship names altogether and use role names instead. For example, the is parent of (or is child of) relationship is sufficiently characterized by the role names parent and child. Note that this convention not only ....

.... UNIFIED MODELING LANGUAGE (UML) roles serve two purposes: they label association ends (the UML term for places of relationships) and they act as type specifiers in the scope of a collaboration (so called classifier roles; the association and association end roles of UML are not considered here) [48]. Because LODWICK does not distinguish between the two purposes, an inevitable clash occurs when trying to specify a UML collaboration in LODWICK, because the association ends rolenames and the classifier roles do not match. An example of this is shown in figure 2. Figure 2: A typical UML ....

....cannot be captured in UML s basic mechanism. OCL defines numerous useful semantics among them are pre post conditioning and composition. Indeed, it shares most of the semantics with Rosetta, which is another on going effort by the System Level Design Language (SLDL) working group. References [5] and [6] contain documents and links related to both OCL and Rosetta, respectively. Being a semi formal, graphical language makes UML an excellent analysis tool. The language constructs support modeling of such desirable system characteristics as concurency, synchronization, and composition, ....
