19-letter words containing c, i, u, d, a, e
- directional coupler — (communications) (tap) A passive device used in cable systems to divide and combine radio frequency signals. A directional coupler has at least three ports: line in, line out, and the tap. The signal passes between line in and line out ports with loss referred to as the insertion loss. A small portion of the signal power applied to the line in port passes to the tap port. A signal applied to the tap port is passed to the line in port less the tap attenuation value. The tap signals are isolated from the line out port to prevent reflections. A signal applied to the line out port passes to the line in port and is isolated from the tap port. Some devices provide more than one tap output line (multi-taps).
- discretionary trust — a trust in which the beneficiaries' shares are not fixed in the trust deed but are left to the discretion of other persons, often the trustees
- discriminated union — (theory) The discriminated union of two sets A and B is A + B = {(inA, a) | a in A} U {(inB, b)| b in B} where inA and inB are arbitrary tags which specify which summand an element originates from. A type (especially an algebraic data type) might be described as a discriminated union if it is a sum type whose objects consist of a tag to say which part of the union they belong to and a value of the corresponding type.

- distinctive feature — a feature of the sound system of a language that serves as the crucial distinguishing mark between two phonemes, as the distinctive feature of voicing, which distinguishes b from p in English, or nasality, which distinguishes m from b and p.
- domain architecture — (systems analysis) A generic, organisational structure or design for software systems in a domain.

- functional database — (database, language) A database which uses a functional language as its query language. Databases would seem to be an inappropriate application for functional languages since, a purely functional language would have to return a new copy of the entire database every time (part of) it was updated. To be practically scalable, the update mechanism must clearly be destructive rather than functional; however it is quite feasible for the query language to be purely functional so long as the database is considered as an argument. One approach to the update problem would use a monad to encapsulate database access and ensure it was single threaded. Alternative approaches have been suggested by Trinder, who suggests non-destructive updating with shared data structures, and Sutton who uses a variant of a Phil Wadler's linear type system. There are two main classes of functional database languages. The first is based upon Backus' FP language, of which FQL is probably the best known example. Adaplan is a more recent language which falls into this category. More recently, people have been working on languages which are syntactically very similar to modern functional programming languages, but which also provide all of the features of a database language, e.g. bulk data structures which can be incrementally updated, type systems which can be incrementally updated, and all data persisting in a database. Examples are PFL [Poulovassilis&Small, VLDB-91], and Machiavelli [Ohori et al, ACM SIGMOD Conference, 1998].
