In the second half of the 20th century researchers tried to improve, simplify and speed up software development by having a look at the fundamental principles behind the architectural development. Applying these software architecture principles helped to design and develop software systems. This paper will introduce the very beginning of software architecture and how it contributed to solving open issues arising with today’s software by comparing abstracts of Parnas and Shaw who published two of the earliest papers in this field.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This paper explores the early development of software architecture, focusing on the contributions of D.L. Parnas and Mary Shaw. It aims to demonstrate the significance of software architecture principles in addressing challenges related to the design and development of complex systems. Through a comparative analysis of Parnas' and Shaw's seminal works, the paper highlights key concepts such as information hiding, modularization, and the need for higher-level abstractions.
- The evolution of software architecture and its role in managing complexity
- The importance of information hiding and modularization in software design
- The need for higher-level abstractions in large-scale systems
- The application of early software architecture principles to contemporary systems
- The future of software architecture and its potential for automation
Zusammenfassung der Kapitel (Chapter Summaries)
- Introduction: This chapter introduces the concept of software architecture and its evolution, highlighting the challenges posed by increasingly complex systems. It establishes the significance of understanding the principles behind software architecture design and development.
- Discussion: This section delves into two seminal papers in software architecture. It examines Parnas' work on "On the Criteria to be Used on Decomposing Systems into Modules," focusing on the concept of information hiding and its impact on software design. It then discusses Shaw's work on "Larger Scale Systems Require Higher-Level Abstractions," emphasizing the importance of architectural abstractions for managing complex systems.
- Critical Analysis: This chapter explores how the principles pioneered by Parnas and Shaw continue to influence modern software architecture. It examines the application of their ideas to contemporary systems and discusses the limitations of their approaches in the context of modern software development.
