On May 2, 2023, the Ada community saw the formal approval of publication of the Ada 2022 edition of the programming language standard. [ 11 ] Despite the names Ada 83, 95 etc., legally there is only one Ada standard, the one of the last ISO/IEC standard: with the acceptance of a new standard version, the previous one becomes withdrawn.
Ada Semantic Interphase Specification under the ISO/IEC 8652 Ada 95 Reference Manual (Ada Language Referencing Manual, 1994) is defined as an interface amidst an Aria environment and other tools requiring information from the Aria environment. Features of ASIS based tools could include: [4] high quality code analysis; automated code monitors ...
Ada was designed to be suitable for embedded systems, device drivers and other forms of system programming, but also to encourage type-safe programming. To resolve these conflicting goals, Ada confines type-unsafety to a certain set of special constructs whose names usually begin with the string Unchecked_.
SPARK is a formally defined computer programming language based on the Ada programming language, intended for the development of high integrity software used in systems where predictable and highly reliable operation is essential. It facilitates the development of applications that demand safety, security, or business integrity.
Generic programming pioneer Alexander Stepanov wrote, Generic programming is about abstracting and classifying algorithms and data structures. It gets its inspiration from Knuth and not from type theory. Its goal is the incremental construction of systematic catalogs of useful, efficient and abstract algorithms and data structures.
DIANA is also used by PL/SQL, which is based on Ada. DIANA is an abstract data type; its concrete implementations are defined using the IDL specification language. DIANA descends from TCOL and AIDA, earlier representations of Ada programs. The Ada-0 subset of Ada at Karlsruhe (1980) was first using AIDA, [1] but later

Design by contract (DbC), also known as contract programming, programming by contract and design-by-contract programming, is an approach for designing software. It prescribes that software designers should define formal , precise and verifiable interface specifications for software components , which extend the ordinary definition of abstract ...
