Role-oriented programming
open-in-new
<p>Role-oriented programming as a form of <a href="/facts/Programming_language/cWTYbgWa">computer programming</a> aims at expressing things in terms that are analogous to human <a href="/facts/Concept/VWB6yhQp">conceptual</a> understanding of the <a href="/facts/World/ceMeHvG3">world</a>. This should make programs easier to understand and maintain. </p><p>The main idea of role-oriented programming is that humans think in terms of <a href="/facts/Role/LDthMhoD">roles</a>. This claim is often backed up by examples of <a href="/facts/Social_relations/DU3HW2Ah">social relations</a>. For example, a student attending a class and the same student at a party are the same person, yet that person plays two different roles. In particular, the interactions of this person with the outside world depend on his current role. The roles typically share features, e.g., the intrinsic properties of being a person. This sharing of properties is often handled by the <a href="/facts/Delegation_(programming)/fhoIL7nh">delegation</a> mechanism. </p><p>In the older literature and in the field of <a href="/facts/Database/VYcpkevb">databases</a>, it seems[<i>original research?</i>] that there has been little consideration for the context in which roles interplay with each other. Such a context is being established in newer role- and <a href="/facts/Aspect-oriented_programming/HK7CFwan">aspect-oriented programming</a> languages such as Object Teams. Compare the use of "role" as "a set of software programs (services) that enable a server to perform specific functions for users or computers on the network" in <a href="/facts/Windows_Server/5t7XxyUV">Windows Server</a> jargon. </p><p>Many[<i>quantify</i>] researchers have argued the advantages of roles in <a href="/facts/Computer_model/Re6o8vzN">modeling</a> and implementation. Roles allow objects to evolve over time, they enable independent and <a href="/facts/Concurrency_(computer_science)/Ctnrrq4A">concurrently</a> existing views (interfaces) of the object, explicating the different contexts of the object, and <a href="/facts/Separation_of_concerns/Tx8jawNT"> separating concerns</a>. Generally roles are a natural element of human daily concept-forming. Roles in programming languages enable objects to have changing interfaces, as we see in <a href="/facts/Real_life/a34ebUXs">real life</a> - things change over time, are used differently in different contexts, etc. </p>
