The article presents two perspectives on software architecture: the view perspective, where the system is the integral of all historical design decisions, and the design decision perspective, where each decision acts as the derivative defining the architecture's evolution direction and speed.
The article explains why AI agents need a dedicated memory system, describes a three‑layer memory architecture (working, short‑term, long‑term), and outlines four critical design decisions—what to write, when to read, how to update/forget, and isolation—illustrated with real‑world examples and industry solutions.
This article explores the critical role of design decisions in software architecture, introduces templates like ADR for documenting decisions, discusses challenges in extracting decision knowledge, and examines how LLMs can mine historical artifacts like GitHub issues to recover lost architectural rationale.
The article explains the importance of documenting software design decisions, introduces Architecture Decision Records (ADRs) as lightweight, text‑based records containing background, decision, and consequences, and discusses their historical evolution, practical benefits, challenges, and growing adoption in agile development.
