  • declarative language — (language)   Any relational language or functional language. These kinds of programming language describe relationships between variables in terms of functions or inference rules, and the language executor (interpreter or compiler) applies some fixed algorithm to these relations to produce a result. Declarative languages contrast with imperative languages which specify explicit manipulation of the computer's internal state; or procedural languages which specify an explicit sequence of steps to follow. The most common examples of declarative languages are logic programming languages such as Prolog and functional languages like Haskell. See also production system.

  • enterprise javabeans — (specification, business, programming)   (EJB) A server-side component architecture for writing reusable business logic and portable enterprise applications. EJB is the basis of Sun's Java 2 Platform, Enterprise Edition (J2EE). Enterprise JavaBean components are written entirely in Java and run on any EJB compliant server. They are operating system, platform, and middleware independent, preventing vendor lock-in. EJB servers provide system-level services (the "plumbing") such as transactions, security, threading, and persistence. The EJB architecture is inherently transactional, distributed, multi-tier, scalable, secure, and wire protocol neutral - any protocol can be used: IIOP, JRMP, HTTP, DCOM etc. EJB 1.1 requires RMI for communication with components. EJB 2.0 is expected to require support for RMI/IIOP. EJB applications can serve assorted clients: browsers, Java, ActiveX, CORBA etc. EJB can be used to wrap legacy systems. EJB 1.1 was released in December 1999. EJB 2.0 is in development. Sun claims broad industry adoption. 30 vendors are shipping server products implementing EJB. Supporting vendors include IBM, Fujitsu, Sybase, Borland, Oracle, and Symantec. An alternative is Microsoft's MTS (Microsoft Transaction Server).
  • environment variable — (programming, operating system)   A variable that is bound in the current environment. When evaluating an expression in some environment, the evaluation of a variable consists of looking up its name in the environment and substituting its value. Most programming languages have some concept of an environment but in Unix shell scripts it has a specific meaning slightly different from other contexts. In shell scripts, environment variables are one kind of shell variable. They differ from local variables and command line arguments in that they are inheritted by a child process. Examples are the PATH variable that tells the shell the file system paths to search to find command executables and the TZ variable which contains the local time zone. The variable called "SHELL" specifies the type of shell being used. These variables are used by commands or shell scripts to discover things about the environment they are operating in. Environment variables can be changed or created by the user or a program. To see a list of environment variables type "setenv" at the csh or tcsh prompt or "set" at the sh, bash, jsh or ksh prompt. In other programming languages, e.g. functional programming languages, the environment is extended with new bindings when a function's parameters are bound to its actual arguments or when new variables are declared. In a block-structured procedural language, the environment usually consists of a linked list of activation records.
  • environmental health — the issues dealt with by the Environmental Health Department of a local authority, such as prevention of the spread of communicable diseases, food safety and hygiene, control of infestation by insects or rodents, etc
  • environmental impact — the impact on the environment created by an industry, service, plan, or project
  • equivalence relation — (mathematics)   A relation R on a set including elements a, b, c, which is reflexive (a R a), symmetric (a R b => b R a) and transitive (a R b R c => a R c). An equivalence relation defines an equivalence class. See also partial equivalence relation.

  • general public virus — (software, legal)   A pejorative name for some versions of the GNU project copyleft or General Public License (GPL), which requires that any tools or application programs incorporating copylefted code must be source-distributed on the same terms as GNU code. Thus it is alleged that the copyleft "infects" software generated with GNU tools, which may in turn infect other software that reuses any of its code.
  • generative phonology — a theory of phonology that uses a set of rules to derive phonetic representations from abstract underlying forms.
  • generative semantics — a theory of generative grammar holding that the deep structure of a sentence is equivalent to its semantic representation, from which the surface structure can then be derived using only one set of rules that relate underlying meaning and surface form rather than separate sets of semantic and syntactic rules.
  • gingival hyperplasia — Gingival hyperplasia is abnormal enlargement of the gums.
  • give one's right arm — to be prepared to make any sacrifice
  • give someone the air — a mixture of nitrogen, oxygen, and minute amounts of other gases that surrounds the earth and forms its atmosphere.
