software system design modeling tool

mathematical program specification intended to allow correctness proofs, including algorithmically

XPDL defines an XML schema for specifying the declarative part of workflow / business process.

Web Modeling Language, (WebML) is a visual notation and methodology for the design of a data-intensive web applications. It provides a graphical means to define the specifics of web application design within a structured design process. This process can be enhanced with the assistance of visual design tools.

TLA+ is a formal specification language developed by Leslie Lamport. It is used for designing, modelling, documentation, and verification of programs, especially concurrent systems and distributed systems. TLA+ is considered to be exhaustively-testable pseudocode,

PROMELA (Process or Protocol Meta Language) is a verification modeling language introduced by Gerard J. Holzmann. The language allows for the dynamic creation of concurrent processes to model, for example, distributed systems. In PROMELA models, communication via message channels can be defined to be synchronous (i.e., rendezvous), or asynchronous (i.e., buffered). PROMELA models can be analyzed with the SPIN model checker, to verify that the modeled system produces the desired behavior. An implementation verified with Isabelle/HOL is also available, as part of the Computer Aided Verification
