| Data design - | (Software Engineering) an activity that translates the data model developed during analysis into implementable data structures |
| Data dictionary - | (Software Engineering) a database that contains definitions of all data items defined during analysis; see also, Requirements dictionary |
| Data warehouse - | (Software Engineering) a large, independent database that has access to databases that serve many different applications that are required by a business |
| Formulation - | (Software Engineering) a Web engineering action that identifies business need, describes WebApp objectives, defines major features and functions, and establishes mechanisms for requirements gathering |
| Interface design - | (Software Engineering) a software engineering action that establishes the structure and workflow for a user interface; follows three "golden rules:" place the user in control, reduce the user's memory leoad, make the interface consistent. |
| Navigation analysis - | (Software Engineering) a Web engineering action that establishes how a user will navigate between various elements (e.g., content, functions) of a WebApp |
| Portability - | (Software Engineering) the ability to transport software from one target environment to another |

| AAC - Autoclaved Aerated Concrete | (Concrete Engineering) Exceptionally lightweight precast concrete with high thermal qualities and fire resistence. Suitable for cutting with ordinary hand tools. Mix design is composed of portland cement, sand or siliceous material, lime, gypsum, finely powdered aluminum, and water. Initial mix is a combination of portland cement, sand, lime and gypsum to produce a slurry. Finely powdered aluminum mixed into a paste is added prior to placement into large, rail-like forms. The finely powdered aluminum reacts with the alkaline components of the cement and lime to produce hydrogen gas, which increases the volume approximately five times producing a uniformly, dispersed cellular structure. Units are cut to required shape. Units are placed in an autoclave, an enclosed pressurized chamber, and steam cured at 3500 F. Approximately 80% of the ultimate volume consists of air voids. |
