Ada Reference Manual

Ada was originally designed with three overriding concerns: program reliability and maintenance,
programming as a human activity, and efficiency. The 1995 revision to the language was designed to
provide greater flexibility and extensibility, additional control over storage management and
synchronization, and standardized packages oriented toward supporting important application areas, while
at the same time retaining the original emphasis on reliability, maintainability, and efficiency. This third
edition provides further flexibility and adds more standardized packages within the framework provided
by the 1995 revision.
