- netware directory services — (networking) (NDS) Novell, Inc.'s directory services for Netware, Windows NT, and Unix. The NDS directory represents each network resource (user, hardware, or application) as an object of a certain class, where each class has certain properties. For example, User and Print Server are object classes and a user has over 80 properties such as name, login, password, department, and title. The directory is hierarchical, divided into branches by rules of containment. A given object can only belong to a given container (or branch). The rules governing classes, properties and, rules of containment are known as the schema.

- object constraint language — (language) (OCL) A formal specification language extension to UML. The Object Constraint Language is a precise text language that provides constraint and object query expressions on an object-oriented model that cannot otherwise be expressed by diagrammatic notation. OCL supplements UML by providing expressions that have neither the ambiguities of natural language nor the inherent difficulty of using complex mathematics. OCL is a descendent of Syntropy, a second-generation object-oriented analysis and design method. The OCL 1.4 definition specified a constraint language. In OCL 2.0, the definition has been extended to include general object query language definitions.

- orthogonal instruction set — (architecture) An instruction set where all (or most) instructions have the same format and all registers and addressing modes can be used interchangeably - the choices of op code, register, and addressing mode are mutually independent (loosely speaking, the choices are "orthogonal"). This contrasts with some early Intel microprocessors where only certain registers could be used by certain instructions. Examples include the PDP-11, 680x0, ARM, VAX.
- paraconsistent probability — (logic) A notion introduced by Florentin Smarandache: The probability (T, I, F) that an event occurs is calculated from different sources which may be contradictory or may overlap information; here T, I, F are real subsets representing the truth, indeterminacy, and falsity percentages respectively, and n_sup = sup(T)+sup(I)+sup(F) > 100. See neutrosophic probability

- st andrews static language — (language) (SASL) A functional programming language designed by Professor David Turner in 1976 whilst at St. Andrews University.
