Line 1: {{Short description\|Programming paradigm based on conceptual understanding of objects}} ~~{{wikify}}~~ {{Use mdy dates\|date=January 2019}} {{Use American English\|date=January 2019}} '''Role-oriented programming''' isas a form of [[programming language\|computer programming]] ~~aimed~~aims at expressing things in ~~same~~ terms asthat ~~our~~are ~~conceptual~~analogous to human [[concept]]ual understanding of the [[world]]. This should make programs easier to understand and maintain.{{citation needed\|date= August 2016}} The main idea of role-oriented programming is that humans think in terms of ~~roles~~[[role]]s. This claim is often backed up by examples of [[social relations]]. For example, a student attending a class and the same student at a party are the same person, ~~but~~ yet ~~plays~~that inperson plays two different roles. In particular, the interactions of this person with the outside world ~~depends~~depend on his current role. The roles ~~typicall~~typically share features, e.g., the intrinsic properties of being a person. This sharing of properties is often handled by the [[Delegation_(programming)\|delegation]] mechanism. In the older literature and in the field of ~~databases~~[[database]]s, it seems{{or\|date=March 2018}} 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 [[aspect-oriented programming]] languages such as ~~PyMeleon and~~ [[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 [[Windows Server]] jargon.<ref>{{cite book \| last1 = Carpenter \| first1 = Tom \| title = Microsoft Windows Server Administration Essentials \| url = https://books.google.com/books?id=6_mmL45Zw0IC \| series = Sybex Serious Skills \| date = July 18, 2011 \| ___location = Indianapolis \| publisher = John Wiley & Sons \| publication-date = 2011 \| page = 9 \| isbn = 9781118148693 \| access-date = 2018-03-07 \| quote = [...] a server role is a set of software programs (services) that enable a server to perform specific functions for users or computers on the network.}}</ref> Many{{quantify\|date=March 2018}} researchers have argued the advantages of roles in [[computer model\|modeling]] and implementation. Roles allow objects to evolve over time, they enable independent and [[Concurrency (computer science)\|concurrently]] existing views (interfaces) of the object, explicating the different contexts of the object, and [[separation of concerns \| separating concerns]]. 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 [[real life]] - things change over time, are used differently in different contexts, etc. explicating the different contexts of the object, and separating concerns.
