The current release is version 2.5.1, released in 2017 and runs nearly 800 pages in length. The UML specification has gone through many version upgrades since its release. OMG accepted the specification and, in November 1997, adopted UML as a standard. OMG is a nonprofit standards organization supported by some of the biggest names in technology, including Red Hat, Microsoft, Salesforce, and Toshiba. In 1997, they submitted their specification to the Object Management Group (OMG) for adoption consideration. Their goal was to unify their work into a single standard and publish it as the Unified Modeling Language (UML). Each had already made significant contributions to the software industry with their own diagramming techniques. In 1996, Rational Software developed the early version of UML under the authorship of Grady Booch, Ivar Jacobson, and James Rumbaugh. Of course, this assumes all parties follow the same diagramming standard. In the same manner, applying a standard to diagramming software would make it possible for any developer in any company to work on any system designed by any architect. The motivation behind creating UML was to mirror the way structural architects use the same methods to draw building blueprints, making it possible for any construction company to put up a high-rise building designed by any architect. Thus came the impetus to create a standard diagramming format. This "getting up to speed" labor can incur significant overhead. An architect changing jobs to a new company had to take the time to learn how the new company's diagrams worked and what they represented. The variety of diagramming styles affected productivity and increased the cost of doing business. It seemed as if every company had its own way of diagramming systems. Some significant enterprise architects and application developers created UML because they got tired of the plethora of roll-your-own diagramming styles prevalent in the industry. However, to get the full benefit from the parts that detail the different diagrams, it's helpful to have a general understanding of application programming and some knowledge of classes, interfaces, and objects. These articles are for a general technical audience. In two companion articles, I offer a more detailed description of UML's particulars, including examples of the various diagram types it supports. This article provides a brief overview of UML's origins. UML provides a standard to describe software systems in a very detailed manner graphically. UML is not getting much attention these days on the front pages of popular technical sites. Take a Linux infrastructure planning assessment.An architect's guide to multicloud infrastructure.Having created the datatypes, code templates, code options, grammar and transformation templates for your new language, you can incorporate and distribute them in an MDG Technology. The process of creating transformation templates is very similar to that for creating code templates.Įdit Transformation Templates Write Transformations If you intend MDA transformations to be made to (or from) your new programming language, you can also edit and create transformation templates for it. To access the grammar editor select the 'Code > Schema > Grammars' ribbon option. Synchronization during code generation so that changes made to the file since it was last generated are not lost.Reverse engineering of existing code into your model. The code options are made available to your models only through an MDG Technology.ĭefining a grammar for your language is an optional step that provides two primary benefits: These are additional settings for the language that are not provided by the data types or code templates, and that help define how the system handles that language when generating and reverse-engineering code. If you prefer, you can also define source code options for your new language. Behavioral Code generation (if this is appropriate)Ĭode Template Framework Code and Transform Templates Create Custom Templates Customize Base Templates.Forward code engineering of your models in the new language.The code templates define how the system should perform: You cannot access the new language in the Code Template Editor until at least one datatype has been added to the language.Īfter you have defined all the datatypes you need, click on the Close button, select the language in the 'Language' field of the Code Template Editor, and start to edit or create the code templates for the new language. In the Code Template Editor, click on the New Language button and, on the 'Programming Languages Datatypes' dialog, click on the Add Product button.Įnter your new programming language name and define the datatypes for it.
