| object: | a concept, abstraction, or thing with crisp boundaries and meanings for the problem at hand; an instance of a class |
| object design: | a stage of the development cycle during which the implementation of each class, association, attribute, and operation is determined |
| object manager: | the collection of procedures and data values that characterize a class of objects |
| object model: | a description of the structure of the objects in a system including their identity, relationships to other objects, attributes, and operations |
| object-oriented: | a software development strategy that organizes software as a collection of objects that contain both data structure and behavoir |
| OMT: | Object Modeling Technique; a software development strategy that uses object, dynamic, and functional models throughout the development life cycle |
| one-copy update semantics: | a model for concurrent access to files in which the processes accessing the file see its contents as if only one copy of it existed |
| one's complement: | an algorithm carried out by inverting all the bits in a binary number |
| OO: | object-oriented |
| OOPS: | object-oriented programming system |
| openness: | the characteristic of a system that determines whether the system can be extended |
| operation: | an action that may be applied to objects in a class |
| origin class: | the topmost class that defines an attribute or operation |
| overflow flag (OV): | the sixth bit in the PSW register; a bit that is set when there is an arithmetic overflow -- when the result of a signed number operation causes the high-order bit to overflow into the sign bit |
| overload: | to define a method with the same name as another method in the same class, but with a different parameter list |
| override: | to define a method for an operation that replaces an inherited method for the same operation |
