Unified Modeling Language

Unified Modeling Language
The Unified Modeling Language (UML) is a general-purpose modeling language in the field of software engineering, which is designed to provide a standard way to visualize the design of a system.[1] It was created and developed by Grady Booch, Ivar Jacobson and James Rumbaugh at Rational Software during 1994–95 with further development led by them through 1996.[1] In 1997 it was adopted as a standard by the Object Management Group (OMG), and has been managed by this organization ever since. In 2000 the Unified Modeling Language was also accepted by the International Organization for Standardization (ISO) as an approved ISO standard. Since then it has been periodically revised to cover the latest revision of UML.[2] Overview[edit] A collage of UML diagrams The Unified Modeling Language (UML) offers a way to visualize a system's architectural blueprints in a diagram (see image), including elements such as:[3] History[edit] History of object-oriented methods and notation Before UML 1.x[edit] [edit]

PMO The Project Management Body of Knowledge (PMBOK) established by the Project Management Institute (PMI) for training certified Project Management Professionals (PMP) discusses the structure of a projectized organization, a common management structure in organizations in which a major component of the value of the business is based upon the success of individual projects into which investments of resources are made based on their potential value.  The projectized organization structured around programs and portfolios is shown in the figure below. Projectized Organization The PMO at each level also assumes responsibility for the resources that are not allocated, and is also responsible for hiring, developing and evaluating resources within their hierarchy.  The PMO then takes on the responsibility for overhead costs associated with personnel development and costs of personnel time that are not billed to a project.

A UML Profile for Data Modeling Unfortunately data modeling is not yet covered by the Unified Modeling Language (UML), even though persistence-related issues are clearly an important aspect of object-oriented software project. For several years I have argued that the UML needs a data model (first in Building Object Applications that Work in 1997 and most recently in Refactoring Databases) and have vacillated between various ways that it should be done. Other methodologists have argued the same (Naiburg and Maksimchuk 2001, Muller 1999) because they too recognize the clear need to extend the UML. Unfortunately we have all come up with slightly different modeling notations, a problem that the UML is supposed to address if my memory serves me correctly. The good news is that the Object Management Group (OMG) issued an RFP for an official UML Data Modeling Profile in December 2005.

Applications of UML This state diagram shows how UML can be used for designing a door system that can only be opened and closed UML (Unified Modeling Language) is very powerful modeling language.[1] We can develop many diagrams using UML and provide users with ready-to-use, expressive modeling examples. UML can be applied in many areas like embedded systems, web applications, commercial applications etc. Some UML tools generate program language code from UML.[2] UML can be used for modeling the whole system independent of platform language. UML is a graphical language for visualizing, specifying, constructing, and documenting information about software-intensive systems.[3] UML gives us a standard way to write a system's view, covering conceptual things such as business processes and system functions, as well as things like classes written in a specific programming language, database schemas, and reusable software components.

Scope (project management) In project management, the term scope has two distinct uses- Project Scope and Product Scope. Scope involves getting information required to start a project, and the features the product would have that would meet its stakeholders requirements. Project Scope Examples of Gliffy UML Diagrams Unified Modeling Language, or UML, is a standard language for visually representing the requirements, analysis, design, and implementation of a system. Bring it all together UML diagrams show structural (static), behavioral (dynamic) and implementation characteristics — and the shape and connector libraries in Gliffy make it easy. Since no single diagram can model a system completely, Gliffy's UML diagram editor makes it easy to add more diagrams as you need them. Just drag and drop from a library of shapes to show any of the nine UML diagrams needed to model a system: Use case diagram Class diagram Object diagram State diagram Activity diagram Sequence diagram Collaboration diagram Component diagram Deployment diagram

List of Unified Modeling Language tools From Wikipedia, the free encyclopedia Jump to navigationJump to search Wikimedia list article This article compares UML tools. UML tools are software applications which support some functions of the Unified Modeling Language. Use case A UMLUse Case Diagram for the interaction of a client (the actor) within a restaurant (the system) In systems engineering, use cases are used at a higher level than within software engineering, often representing missions or stakeholder goals. The detailed requirements may then be captured in Systems Modeling Language (SysML) or as contractual statements. Use Cases are an important requirement technique that have been widely used in modern software engineering since their formal introduction by Ivar Jacobson in 1992. Use case driven development is a key characteristic of process models and frameworks such as the Unified Process (UP), Rational Unified Process (RUP), and Oracle Unified Method (OUM). With its iterative and evolutionary nature, the use case is also a good fit for agile development.

Rational Unified Modeling Language - UML Resource Center The Unified Modeling Language™ UML is a visual language for specifying, constructing, and documenting the artifacts of software-intensive systems. Complex software designs difficult for you to describe with text alone can readily be conveyed through diagrams using UML. Modeling provides three key benefits: Scope Management Plan Template Introduction Scope Management is the collection of processes which ensure that the project includes all the work required to complete it while excluding all work which is not necessary to complete it. The Scope Management Plan details how the project scope will be defined, developed, and verified. It clearly defines who is responsible for managing the projects’ scope and acts as a guide for managing and controlling the scope. Project Scope Management follows a five step process; Collect Requirements, Define Scope, Create WBS, Verify Scope, and Control Scope.

Visual Paradigm for UML Visual Paradigm for UML (VP-UML) is a UML CASE Tool supporting UML 2, SysML and Business Process Modeling Notation (BPMN) from the Object Management Group (OMG). In addition to modeling support, it provides report generation and code engineering capabilities including code generation. It can reverse engineer diagrams from code, and provide round-trip engineering for various programming languages. Product Editions[edit] Higher-priced editions provide more features.[3] The following editions were available in November 2010: Requirements elicitation In requirements engineering, requirements elicitation is the practice of collecting the requirements of a system from users, customers and other stakeholders. [1] The practice is also sometimes referred to as requirements gathering. The term elicitation is used in books and research to raise the fact that good requirements can not just be collected from the customer, as would be indicated by the name requirements gathering. Requirements elicitation is non-trivial because you can never be sure you get all requirements from the user and customer by just asking them what the system should do. Requirements elicitation practices include interviews, questionnaires, user observation, workshops, brainstorming, use cases, role playing and prototyping. Before requirements can be analyzed, modeled, or specified they must be gathered through an elicitation process. Commonly used elicitation processes are the stakeholder meetings or interviews.

Visual Paradigm Company Overview Visual Paradigm International continuously strives to empower organizations to develop quality applications — faster, better and cheaper. We help our customers to understand their organizations and translate requirements into quality software with our tools that are both richly featured and simple to use. As the saying goes, a picture is worth a thousand words. We do see visual modeling a great way to communicate efficiently, especially during project crunch times.
