ADA
n 1: an enzyme found in mammals that can catalyze the
deamination of adenosine into inosine and ammonia; "ADA
deficiency can lead to one form of severe combined
immunodeficiency disease"; "the gene encoding ADA was one
of the earlier human genes to be isolated and cloned for
study" [synonym: {adenosine deaminase}, {ADA}]

(After {Ada Lovelace}) A {Pascal}-descended
language, designed by Jean Ichbiah's team at {CII Honeywell}
in 1979, made mandatory for Department of Defense software
projects by the Pentagon. The original language was
standardised as "Ada 83", the latest is "{Ada 95}".

Ada is a large, complex, {block-structured} language aimed
primarily at {embedded} applications. It has facilities for
{real-time} response, {concurrency}, hardware access and
reliable run-time error handling. In support of large-scale
{software engineering}, it emphasises {strong typing}, {data
abstraction} and {encapsulation}. The type system uses {name
equivalence} and includes both {subtypes} and {derived types}.
Both fixed and {floating-point} numerical types are supported.

{Control flow} is fully bracketed: if-then-elsif-end if,
case-is-when-end case, loop-exit-end loop, goto. Subprogram
parameters are in, out, or inout. Variables imported from
other packages may be hidden or directly visible. Operators
may be {overloaded} and so may {enumeration} literals. There
are user-defined {exceptions} and {exception handlers}.

An Ada program consists of a set of packages encapsulating
data objects and their related operations. A package has a
separately compilable body and interface. Ada permits
{generic packages} and subroutines, possibly parametrised.

Ada support {single inheritance}, using "tagged types" which
are types that can be extended via {inheritance}.

Ada programming places a heavy emphasis on {multitasking}.
Tasks are synchronised by the {rendezvous}, in which a task
waits for one of its subroutines to be executed by another.
The conditional entry makes it possible for a task to test
whether an entry is ready. The selective wait waits for
either of two entries or waits for a limited time.

Ada is often criticised, especially for its size and
complexity, and this is attributed to its having been designed
by committee. In fact, both Ada 83 and Ada 95 were designed
by small design teams to be internally consistent and tightly
integrated. By contrast, two possible competitors, {Fortran
90} and {C} have both become products designed by large and
disparate volunteer committees.
