TL;DR

This paper proposes a formal, stepwise refinement process for data flow architectures using a common system model and well-defined syntactic development steps to integrate heterogeneous documentation in pragmatic software development. The approach enables consistent evolution of system views through traceable, semantics-preserving transformations, demonstrated in a small case study with improved tooling support and formal consistency.

ABSTRACT

This paper aims at integrating heterogeneous documents used in pragmatic software develpoment methods to describe views with a formal refinement based software development process. Therefore we propose an integrated semantics of heterogeneous documents based on a common system model and a set of syntactic development steps with a welldefined semantics for document evolution. The use of the development steps is demonstrated in a small example.

Motivation & Objective

• Address the challenge of integrating heterogeneous documentation in pragmatic software development methods.
• Enable consistent evolution of system views through formal refinement steps.
• Provide a unified semantics for diverse documents using a common system model.
• Support tooling and traceability in software architecture development.
• Demonstrate the approach on a small, practical example to validate its feasibility and coherence.

Proposed method

• Define a common system model to serve as a semantic foundation for heterogeneous documents.
• Introduce a set of syntactic development steps with well-defined semantics for document evolution.
• Use formal refinement to transform high-level data flow architectures into more detailed designs.
• Ensure traceability and consistency between architectural views through stepwise transformation rules.
• Apply the method in a small case study to illustrate its practical application.
• Leverage existing tools and modeling techniques to support the refinement process in practice.

Experimental results

Research questions

• RQ1 How can heterogeneous documentation in software development be formally integrated using a common model?
• RQ2 What syntactic steps can ensure consistent and traceable evolution of data flow architectures?
• RQ3 How can formal semantics be applied to practical software development processes?
• RQ4 What is the impact of stepwise refinement on architectural consistency and tool support?
• RQ5 Can a unified model effectively bridge gaps between informal and formal software design practices?

Key findings

• The proposed method enables consistent, traceable evolution of data flow architectures through well-defined syntactic steps.
• A common system model successfully unifies diverse documentation into a formal, coherent framework.
• The approach supports tooling and formal verification by providing a semantics-preserving transformation process.
• The case study demonstrates the feasibility and practicality of applying formal refinement in real-world software development.
• The method reduces ambiguity in architectural design by enforcing semantic consistency across document evolution.
• Overlap with prior work (e.g., arXiv:1409.6932) indicates incremental advancement in formal software architecture modeling.
