What is Cloudfier and why you may want to use it

Cloudfier is a tool for developing business applications based on executable models. But why would you want to do that? , you may be asking. After all, you have been happily building business applications using Java EE, .Net, Ruby on Rails, Node.js or something similar. What is the problem with developing business applications with those tools? Let me try to describe what I believe is the problem: Information management applications are all about understanding the business domain and providing domain­-centric features that serve the needs of the various business stakeholders.

Cloudfier is an attempt at avoiding the threat of tying your business application irreversibly to a concrete implementation technology by promoting a complete separation between business domain and technological concerns. Cloudfier programs are UML models Cloudfier programs are actually UML 2.5 models. There is a catch though… Cloudfier uses TextUML, a textual notation for UML1 Build locally.

Use Case Model. A Use Case Model describes the proposed functionality of a new system.

Use Case Model

A Use Case represents a discrete unit of interaction between a user (human or machine) and the system. This interaction is a single unit of meaningful work, such as Create Account or View Account Details. Each Use Case describes the functionality to be built in the proposed system, which can include another Use Case's functionality or extend another Use Case with its own behavior. A Use Case description will generally includes: General comments and notes describing the use case. Actors Use Cases are typically related to 'actors', which are human or machine entities that use or interact with the system to perform a piece of meaningful work that helps them to achieve a goal. Includes and Extends relationships between Use Cases One Use Case could include the functionality of another as part of its normal processing. One Use Case can extend the behavior of another, typically when exceptional circumstances are encountered.

Practical UML™: A Hands-On Introduction for Developers. The heart of object-oriented problem solving is the construction of a model.

Practical UML™: A Hands-On Introduction for Developers

The model abstracts the essential details of the underlying problem from its usually complicated real world. Several modeling tools are wrapped under the heading of the UML™, which stands for Unified Modeling Language™. The purpose of this course is to present important highlights of the UML. At the center of the UML are its nine kinds of modeling diagrams, which we describe here. Some of the sections of this course contain links to pages with more detailed information. Why is UML important? Let's look at this question from the point of view of the construction trade. DrJava.

Bash

Está basado en la shell de Unix y es compatible con POSIX. Fue escrito para el proyecto GNU y es el intérprete de comandos por defecto en la mayoría de las distribuciones de GNU con Linux. Su nombre es un acrónimo de Bourne-Again Shell (otro shell bourne) — haciendo un juego de palabras (born-again significa renacimiento) sobre el Bourne shell (sh), que fue uno de los primeros intérpretes importantes de Unix. Hacia 1978 Bourne era el intérprete distribuido con la versión del sistema operativo Unix Versión 7.

Stephen Bourne, por entonces investigador de los Laboratorios Bell, escribió la versión original de Bourne. Sintaxis de Bash[editar] La sintaxis de órdenes de Bash es un superconjunto de instrucciones basadas en la sintaxis del intérprete Bourne. La sintaxis de Bash tiene muchas extensiones que no proporciona el intérprete Bourne. Acceso a los parámetros[editar] Abre y cierra archivos.
