UML tool

Abstract: Today, a software designer or architect who seeks to represent the design of a software system can choose from a wide variety of notational languages, each aligned with a particular analysis and design methodology. Ironically, this wide variety of choice is one impediment to the significant benefits promised by software reuse. The emergence of the Unified Modeling Language (UML) -- created by the joint efforts of leading object technologists Grady Booch, Ivar Jacobson, and James Rumbaugh with contributions from many others in the object community -- represents one of the most significant developments in object technology. Supported by a broad base of industry-leading companies, the UML merges the best of the notations used by the three most popular analysis and design methodologies, Booch, OOSE (use-cases), and OMT, to produce a single, universal modeling language that can be used with any method.Written for those already grounded in object-oriented analysis and design, this concise overview introduces you to UML, highlighting the key elements of its notation, semantics, and processes. Included is a brief explanation of UML's history, development, and rationale, as well as discussions on how UML can be integrated into the object-oriented development process. In addition, the book profiles various modeling techniques associated with UML -- use cases, CRC cards, design by contract, dynamic classification, interfaces, and abstract classes -- along with concise descriptions of notation and semantics and numerous insightful tips for effective use based on the authors' experience. In addition, the authors offer the first look at the emerging Objectory Software Development Process derivedfrom the methodologies of Grady Booch, Ivar Jacobson, and James Rumbaugh. To give you a feel for the UML in action, the book includes a Java programming example that outlines the implementation of a UML-based design.You will come away with an excellent understanding of UML essentials, insight into how UML functions within the software development process, and a firm foundation upon which to expand and build your knowledge of the Unified Modeling Language.

Abstract: Developing secure-critical systems is difficult and there are many well-known examples of security weaknesses exploitedin practice. Thus a sound methodology supporting secure systems development is urgently needed.Our aim is to aid the difficult task of developing security-critical systems in an approach basedon the notation of the Unified Modeling Language. We present the extension UMLsec of UML that allows to express securityrelevant information within the diagrams in a system specification. UMLsec is defined in form of a UML profile using the standard UML extension mechanisms. In particular, the associatedc onstraints give criteria to evaluate the security aspects of a system design, by referring to a formal semantics of a simplifiedfragm ent of UML. We demonstrate the concepts with examples.

Abstract: “If you are a serious user of UML, there is no other book quite like this one. I have been involved with the UML specification process for some time, but I still found myself learning things while reading through this book-especially on the changes and new capabilities that have come with UML.” i¾ i¾ i¾ i¾ i¾ i¾ i¾ i¾ i¾ -Ed Seidewitz, Chief Architect, IntelliData Technologies CorporationThe latest version of the Unified Modeling Language-UML 2.0-has increased its capabilities as the standard notation for modeling software-intensive systems. Like most standards documents, however, the official UML specification is difficult to read and navigate. In addition, UML 2.0 is far more complex than previous versions, making a thorough reference book more essential than ever.In this significantly updated and expanded edition of the definitive reference to the standard, James Rumbaugh, Ivar Jacobson, and Grady Booch-the UML's creators-clearly and completely describe UML concepts, including major revisions to sequence diagrams, activity models, state machines, components, internal structure of classes and components, and profiles. Whether you are capturing requirements, developing software architectures, designing implementations, or trying to understand existing systems, this is the book for you.Highlights include: Alphabetical dictionary of articles covering every UML concept Integrated summary of UML concepts by diagram type Two-color diagrams with extensive annotations in blue Thorough coverage of both semantics and notation, separated in each article for easy reference Further explanations of concepts whose meaning or purpose is obscure in the original specifications Discussion sections offering usage advice and additional insight into tricky concepts Notation summary, with references to individual articles A hyperlinked version of the book in Adobe Reader format on CD-ROM, an excellent resource for browsing or searching the text for specific information An enhanced online index available on the book's web site allowing readers to quickly and easily search the entire text for specific topicsThe result is an indispensable resource for anyone who needs to understand the inner workings of the industry standard modeling language.
