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. 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] UML 1.x[edit] UML 2.x[edit] There are four parts to the UML 2.x specification: Modeling[edit] Related:  Arquitectura Conducida por Modelos: Principios y Prácticas

LPI Linux Certification This book covers the Linux Professional Institute™ family of certifications. There are three levels of LPI™ certification: Level 1: Junior Level Linux Professional.Level 2: Advanced Level Linux Professional.Level 3: Senior Level Linux Professional. To obtain a certification, a candidate is required to pass exams and, for Level 2 and Level 3, to hold a lower-level certification from the LPI™. Audience[edit] This book is written specifically for the LPIC candidate. About this book[edit] This book is organized so that each and every module can be accessed via the front page. Lastly, we are obviously looking for Authors, We encourage all positive edits even if it is just to correct a simple spelling mistake or fix a link; in short, "Every addition is very welcome."

Round-trip engineering Round-trip engineering (RTE) is a functionality of software development tools that synchronizes two or more related software artifacts, such as, source code, models, configuration files, and other documents. The need for round-trip engineering arises when the same information is present in multiple artifacts and therefore an inconsistency may occur if not all artifacts are consistently updated to reflect a given change. For example, some piece of information was added to/changed in only one artifact and, as a result, it became missing in/inconsistent with the other artifacts. Round-trip engineering is closely related to traditional software engineering disciplines: forward engineering (creating software from specifications), reverse engineering (creating specifications from existing software), and reengineering (understanding existing software and modifying it).

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.

10 code snippets to interact with Twitter 1 – Autofollow script (PHP) This code allow you to automatically follow user who have tweeted about a specific term. For example, if you want to follow all users who tweeted about php, simply give it as a value to the $term variable on line 7. Source : 2 – Get the number of follower in full text (PHP) When you have a website or blog and use Twitter, it can be cool to display how many followers you have. <? Source : Rarst on 3 – View who doesn’t follow you (Python) Some people don’t like the idea of following people who don’t follow you back.

Estado Actual del Modelado Code reuse Code reuse, also called software reuse, is the use of existing software, or software knowledge, to build new software,[1] following the reusability principles. Overview[edit] Ad hoc code reuse has been practiced from the earliest days of programming. Code reuse is the idea that a partial computer program written at one time can be, should be, or is being used in another program written at a later time. The general practice of using a prior version of an extant program as a starting point for the next version, is also a form of code reuse. Some so-called code "reuse" involves simply copying some or all of the code from an existing program into a new one. Many researchers have worked to make reuse faster, easier, more systematic, and an integral part of the normal process of programming. Another, newer means is to use software "generators", programs which can create new programs of a certain type, based on a set of parameters that users choose. Types of reuse[edit] Examples[edit]

List of Unified Modeling Language tools From Wikipedia, the free encyclopedia This article compares Unified Modeling Language tools. General[edit] Features[edit] References[edit] External links[edit] Lambda calculus The lowercase lambda, the 11th letter of the Greek alphabet, is used to symbolize the lambda calculus. Because of the importance of the notion of variable binding and substitution, there is not just one system of lambda calculus, and in particular there are typed and untyped variants. Historically, the most important system was the untyped lambda calculus, in which function application has no restrictions (so the notion of the domain of a function is not built into the system). Lambda calculus in history of mathematics[edit] The lambda calculus was introduced by mathematician Alonzo Church in the 1930s as part of an investigation into the foundations of mathematics.[5][6] The original system was shown to be logically inconsistent in 1935 when Stephen Kleene and J. Informal description[edit] Motivation[edit] Computable functions are a fundamental concept within computer science and mathematics. can be rewritten in anonymous form as (read as "the pair of and is mapped to "). can be reworked into

Framework-specific modeling language A framework-specific modeling language [1] (FSML) is a kind of domain-specific modeling language which is designed for an object-oriented application framework. FSMLs define framework-provided abstractions as FSML concepts and decompose the abstractions into features. The features represent implementation steps or choices. A FSML concept can be configured by selecting features and providing values for features. Such a concept configuration represents how the concept should be implemented in the code. In other words, concept configuration describes how the framework should be completed in order to create the implementation of the concept. Applications[edit] FSMLs are used in model-driven development for creating models or specifications of software to be built. Examples[edit] Eclipse Workbench Part Interaction FSML [2] [3] An example FSML for modeling Eclipse Parts (that is, editors and views) and Part Interactions (for example listens to parts, requires adapter, provides selection).

Professional certification (computer technology) Professional certifications in computer technology are non-degree awards made to those who have achieved qualifications specified by a certifying authority. Depending on the particular certification, qualifications may include completing a course of study, proof of professional accomplishments, achieving a specified grade on an examination or some combination thereof. The intention is to establish that an individual holding a certification is technically qualified to hold certain types of position within the field. Certifications, generally, need to be renewed periodically, or may be valid for a specific period (e.g. the lifetime of the product upon which the individual is certified). As a part of a complete renewal of an individual's certification, it is common for the individual to show evidence of continual learning — often termed continuing education — or earning continuing education units (CEU). Certification is formally defined by Krutz and Vines as: The U.S.
