  • dalton's atomic theory — the theory that matter consists of indivisible particles called atoms and that atoms of a given element are all identical and can neither be created nor destroyed. Compounds are formed by combination of atoms in simple ratios to give compound atoms (molecules). The theory was the basis of modern chemistry
  • damn with faint praise — If someone damns something with faint praise, they say something about it which sounds quite nice but is not enthusiastic, and shows that they do not have a high opinion of it.
  • dashing white sergeant — a lively Scottish dance for sets of six people
  • data address generator — (architecture)   (DAG) The mechanism which generates temporary memory addresses for data that is transferred between memory and registers in a Digital Signal Processor. Certain DSP architectures incorporate more than one DAG to simplify the programming needed to move blocks of data between buffers. For instance, certain Fast Fourier Transform algorithms requiring bit reversing, can use the DAG for that purpose, or they can use two DAGS, one for Program Memory Data (PMD), and the other for Data Memory Data (DMD).
  • database administrator — (job)   A person responsible for the design and management of one or more databases and for the evaluation, selection and implementation of database management systems. In smaller organisations, the data administrator and database administrator are often one in the same; however, when they are different, the database administrator's function is more technical. The database administrator would implement the database software that meets the requirements outlined by the organisation's data administrator and systems analysts. Tasks might include controling an organisation's data resources, using data dictionary software to ensure data integrity and security, recovering corrupted data and eliminating data redundancy and uses tuning tools to improve database performance.
  • database normalisation — (database)   A series of steps followed to obtain a database design that allows for efficient access and storage of data in a relational database. These steps reduce data redundancy and the chances of data becoming inconsistent. A table in a relational database is said to be in normal form if it satisfies certain constraints. Codd's original work defined three such forms but there are now five generally accepted steps of normalisation. The output of the first step is called First Normal Form (1NF), the output of the second step is Second Normal Form (2NF), etc. First Normal Form eliminates repeating groups by putting each value of a multi-valued attribute into a new row. Second Normal Form eliminates functional dependencies on a partial key by putting the fields in a separate table from those that are dependent on the whole key. Third Normal Form eliminates functional dependencies on non-key fields by putting them in a separate table. At this stage, all non-key fields are dependent on the key, the whole key and nothing but the key. Fourth Normal Form separates independent multi-valued facts stored in one table into separate tables. Fifth Normal Form breaks out data redundancy that is not covered by any of the previous normal forms.
  • days of wine and roses — a period of happiness and prosperity.
  • decimal classification — a system of classifying books in libraries by the use of numbers with decimals

  • delayed-action shutter — a camera shutter that opens after an interval set by the photographer
  • denotational semantics — (theory)   A technique for describing the meaning of programs in terms of mathematical functions on programs and program components. Programs are translated into functions about which properties can be proved using the standard mathematical theory of functions, and especially domain theory. Compare axiomatic semantics, operational semantics, standard semantics.
  • descriptive cataloging — the aspect of cataloging concerned with the bibliographic and physical description of a book, recording, or other work, accounting for such items as author or performer, title, edition, and imprint as opposed to subject content.
  • design system language — J. Gaffney, Evans & Sutherland 1976. Interpretive FORTH-like language for 3d graphics databases. Earliest forerunner of both Interpress and PostScript. Mentioned in PostScript Language Reference Manual, Adobe Systems, A-W 1985.

  • diachronic linguistics — historical linguistics.
  • digital control system — (systems)   (DCS) A digital computer used for real-time control of a dynamic system, usually in an industrial environment, possibly as part of a Supervisory Control and Data Acquisition (SCADA) system. A DCS samples feedback from the system under control and modifies the control signals in an attempt to achieve some desired behaviour. Analysis of such digital-analogue feedback systems can involve mathematical methods such as difference equations, Laplace transforms, z transfer functions, state space models and state transition matrices.
