The WARS Architectural Style
\"Style is everything. I mean, the blues are three chords. But every guy that plays the blues plays differently, because that\'s their own style. Right?\"
The open source software community is building a wall to contain Mic
Tutorial Details:
The Model, View, and Controller roles of the MVC architectural style have been offered as a means of categorizing components in web application frameworks, but in my previous article on this topic, I argued that the attempts to implement these distinctions have failed to show that this is a correct approach. The primary evidence of this failure is the absence of a single component framework that has managed to isolate the concerns of its components into Model, View, and Controller interfaces.
A correct approach would be to create a new hypothetical style that describes best practices already used in the problem space, instead of prescribing an architectural style from a distantly related problem space. Then the hypothetical new style should be tested through implementation. Any flaws uncovered in the style should be addressed in the refactoring stage, and the cycle repeats itself: hypothesize, implement, refactor.
If these principles are applied to the complex systems that drive dynamic web applications on the server side, we find a family of roles, which should be utterly unsurprising. The roles I outlined in my first article have themselves undergone a refactoring. I\'ve renamed the DataSource interface to State because of confusion between it and javax.sql.DataSource, and also removed the Presentation interface entirely. Presentation components are officially beyond the scope of this problem space, but the representation of the application\'s state is not.
A Representation subsystem to limit the complexity of the State for component developers by restructuring or \"pre-chewing\" the state to make it more intuitive for component developers.
I\'ve been notified of a better term than \"pattern\" to describe what to call this collection of roles. It\'s just an \"architectural style.\" Nothing more, and simply put. I call this architectural style WARS, which is very appropriate considering the use to which we put it in designing Java web apps.
