Using the UML for Architectural Description?
Using the UML for Architectural Description? Rich Hilliard Integrated Systems and Internet Solutions, Inc. Concord, MA USA [email protected] Abstract. There is much interest in using the Unified Modeling Lan- guage (UML) for architectural description { those techniques by which architects sketch, capture, model, document and analyze architectural knowledge and decisions about software-intensive systems. IEEE P1471, the Recommended Practice for Architectural Description, represents an emerging consensus for specifying the content of an architectural descrip- tion for a software-intensive system. Like the UML, IEEE P1471 does not prescribe a particular architectural method or life cycle, but may be used within a variety of such processes. In this paper, I provide an overview of IEEE P1471, describe its conceptual framework, and investigate the issues of applying the UML to meet the requirements of IEEE P1471. Keywords: IEEE P1471, architectural description, multiple views, view- points, Unified Modeling Language 1 Introduction The Unified Modeling Language (UML) is rapidly maturing into the de facto standard for modeling of software-intensive systems. Standardized by the Object Management Group (OMG) in November 1997, it is being adopted by many organizations, and being supported by numerous tool vendors. At present, there is much interest in using the UML for architectural descrip- tion: the techniques by which architects sketch, capture, model, document and analyze architectural knowledge and decisions about software-intensive systems. Such techniques enable architects to record what they are doing, modify or ma- nipulate candidate architectures, reuse portions of existing architectures, and communicate architectural information to others. These descriptions may the be used to analyze and reason about the architecture { possibly with automated support.

UML Tutorial: Part 1 -- Class Diagrams
UML Tutorial: Part 1 -- Class Diagrams. Robert C. Martin My next several columns will be a running tutorial of UML. The 1.0 version of UML was released on the 13th of January, 1997. The 1.1 release should be out before the end of the year. This col- umn will track the progress of UML and present the issues that the three amigos (Grady Booch, Jim Rumbaugh, and Ivar Jacobson) are dealing with. Introduction UML stands for Uniﬁed Modeling Language. It represents a uniﬁcation of the concepts and nota- tions presented by the three amigos in their respective books1. The goal is for UML to become a common language for creating models of object oriented computer software. In its current form UML is comprised of two major components: a Meta-model and a notation. In the future, some form of method or process may also be added to; or associated with, UML. The Meta-model UML is unique in that it has a standard data representation. This representation is called the meta- model. The meta-model is a description of UML in UML. It describes the objects, attributes, and relationships necessary to represent the concepts of UML within a software application. This provides CASE manufacturers with a standard and unambiguous way to represent UML models. Hopefully it will allow for easy transport of UML models between tools. It may also make it easier to write ancillary tools for browsing, summarizing, and modifying UML models. A deeper discussion of the metamodel is beyond the scope of this column. Interested readers can learn more about it by downloading the UML documents from the rational web site2.

Sysml Distilled: a Brief Guide to the Systems Modeling Language
ptg11539604 Praise for SysML Distilled “In keeping with the outstanding tradition of Addison-Wesley’s techni- cal publications, Lenny Delligatti’s SysML Distilled does not disappoint. Lenny has done a masterful job of capturing the spirit of OMG SysML as a practical, standards-based modeling language to help systems engi- neers address growing system complexity. This book is loaded with matter-of-fact insights, starting with basic MBSE concepts to distin- guishing the subtle differences between use cases and scenarios to illu- mination on namespaces and SysML packages, and even speaks to some of the more esoteric SysML semantics such as token flows.” — Jeff Estefan, Principal Engineer, NASA’s Jet Propulsion Laboratory “The power of a modeling language, such as SysML, is that it facilitates communication not only within systems engineering but across disci- plines and across the development life cycle. Many languages have the ptg11539604 potential to increase communication, but without an effective guide, they can fall short of that objective. In SysML Distilled, Lenny Delligatti combines just the right amount of technology with a common-sense approach to utilizing SysML toward achieving that communication. Having worked in systems and software engineering across many do- mains for the last 30 years, and having taught computer languages, UML, and SysML to many organizations and within the college setting, I find Lenny’s book an invaluable resource. He presents the concepts clearly and provides useful and pragmatic examples to get you off the ground quickly and enables you to be an effective modeler.” — Thomas W. Fargnoli, Lead Member of the Engineering Staff, Lockheed Martin “This book provides an excellent introduction to SysML.

A Study on Process Description Method for DFM Using Ontology
Invited Paper A Study on Process Description Method for DFM Using Ontology K. Hiekata1 and H. Yamato2 1Department of Systems Innovation, Graduate School of Engineering, The University of Tokyo, 5-1-5, Kashiwanoha, Kashiwa-city, Chiba 277-8563, Japan 2Department of Human and Engineered Environmental Studies, Graduate School of Frontier Sciences, The University of Tokyo, 5-1-5, Kashiwanoha, Kashiwa-city, Chiba 277-8563, Japan [email protected], [email protected] Abstract A method to describe process and knowledge based on RDF which is an ontology description language and IDEF0 which is a formal process description format is proposed. Once knowledge of experienced engineers is embedded into the system the knowledge will be lost in the future. A production process is described in a proposed format similar to BOM and the process can be retrieved as a flow diagram to make the engineers to understand the product and process. Proposed method is applied to a simple production process of common sub-assembly of ships for evaluation. Keywords: Production process, DFM, Ontology, Computer system 1 INTRODUCTION (Unified Resource Identifier) is assigned to all the objects, There are many research and computer program for and metadata is defined for all objects using the URI. supporting optimization of production process in Metadata is defined as a statement with subject, shipyards. And knowledge of experienced engineers is predicate and object. The statement is called triple in embedded into the system. Once the knowledge is RDF. Two kinds of elements, Literal or Resource, can be embedded into computer system, the knowledge is not a component of a statement.

Using Telelogic DOORS and Microsoft Visio to Model and Visualize Complex Business Processes
Using Telelogic DOORS and Microsoft Visio to Model and Visualize Complex Business Processes “The Business Driven Application Lifecycle” Bob Sherman Procter & Gamble Pharmaceuticals [email protected] Michael Sutherland Galactic Solutions Group, LLC [email protected] Prepared for the Telelogic 2005 User Group Conference, Americas & Asia/Pacific http://www.telelogic.com/news/usergroup/us2005/index.cfm 24 October 2005 Abstract: The fact that most Information Technology (IT) projects fail as a result of requirements management problems is common knowledge. What is not commonly recognized is that the widely haled “use case” and Object Oriented Analysis and Design (OOAD) phenomenon have resulted in little (if any) abatement of IT project failures. In fact, ten years after the advent of these methods, every major IT industry research group remains aligned on the fact that these projects are still failing at an alarming rate (less than a 30% success rate). Ironically, the popularity of use case and OOAD (e.g. UML) methods may be doing more harm than good by diverting our attention away from addressing the real root cause of IT project failures (when you have a new hammer, everything looks like a nail). This paper asserts that, the real root cause of IT project failures centers around the failure to map requirements to an accurate, precise, comprehensive, optimized business model. This argument will be supported by a using a brief recap of the history of use case and OOAD methods to identify differences between the problems these methods were intended to address and the challenges of today’s IT projects.

Extreme Programming and Rational Unified Process – Contrasts Or Synonyms?
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Research Papers in Economics EXTREME PROGRAMMING AND RATIONAL UNIFIED PROCESS – CONTRASTS OR SYNONYMS? Ionel IACOB, PhD Faculty of Computer Science for Business Management, Romanian – American University, Bucharest, Romania ABSTRACT The agile movement has received much attention in software engineering recently. Established methodologies try to surf on the wave and present their methodologies a being agile, among those Rational Unified Process (RUP). In order to evaluate the statements we evaluate the RUP against eXtreme Programming (XP) to find out to what extent they are similar end where they are different. We use a qualitative approach, utilizing a framework for comparison. RUP is a top-down solution and XP is a bottom-up approach. Which of the two is really best in different situations has to be investigated in new empirical studies. 1. INTRODUCTION The agile movement has appeared the last years as an alternative direction for software engineering [1]. Among the agile methodologies, eXtreme Programming (XP) is the most well known [2]. In the current agile boom, many established software engineering methodologies try to present themselves as being agile. The Rational Unified Processes (RUP) [16] is among those, providing “plugins” to RUP for eXtreme Programming1. Thereby they offer a downsized version of RUP, which is stated to be lightweight, agile style. Both methodologies share some common characteristics; they are iterative, customer-oriented and role- based. RUP is generally not considered agile; rather it is criticized for being too extensive and heavyweight [21]. RUP comprises 80 artifacts while XP only stresses the code.
