Ruby (programming language)
Matsumoto defined it this way in an interview:Ruby is object-oriented: every value is an object, including classes and instances of types that many other languages designate as primitives (such as integers, booleans, and "null"). Variables always hold references to objects. Every function is a method and methods are always called on an object. Methods defined at the top level scope become methods of the Object class. Since this class is an ancestor of every other class, such methods can be called on any object. They are also visible in all scopes, effectively serving as "global" procedures. Ruby supports inheritance with dynamic dispatch, mixins and singleton methods (belonging to, and defined for, a single instance rather than being defined on the class). Though Ruby does not support multiple inheritance, classes can import modules as mixins.
Subject-oriented business process management
In many natural languages, subject, predicate and object are the basic building blocks of a sentence. The subject of a sentence is the person, place, thing, or idea that is carrying out the action denoted by the predicate. A predicate has at its center a simple predicate, which is always the verb or verbs linked to the subject. The direct object is the person or thing that receives the action of the verb. It normally follows the verb. The indirect object is the person or thing to whom or to which the action was directed or for whom or for which the action was performed. The indirect object is in a way the recipient of the direct object.
