Ada 2005

Ada 2005 is the most recent revision of the Ada programming language, which was originally standardized by the U.S. Department of Defense in the late 1970s as a general-purpose language for systems programming. Ada has evolved through several versions that introduce new features to enhance software quality, maintainability, and productivity. Ada 2005 introduced significant improvements over its predecessor, including support for object-oriented programming constructs, real-time scheduling features with time triggers and relative delay statements so that tasks can communicate more easily in real-time applications. The language also includes additional predefined libraries (such as containers) and enhanced support for systems programming needs such as concurrency control and reduced runtime overhead from better implementation-defined type coercion rules.
